Audiometers; Audiometric Booths

Scope of this Product Comparison

This Product Comparison covers pure-tone audiometers used in routine testing and screening for hearing

threshold, as well as pure-tone audiometers with speech audiometry capabilities. Also covered are portable and

nonportable single- and double-room audiometric booths that have either single- or double-wall construction.

Tympanometers, middle-ear analyzers, auditory evoked-potential units, and newborn hearing screening

devices are excluded. For more information, see the Product Comparisons titled Recorders, Graphic, Evoked-

Potential; Electromyographs; Electronystagmographs and Auditory Function Screening Devices, Newborn. These devices are also called: audiometric evoked-potential

units, audio spectrum analyzers, tinnitus masker analyzers,

acoustic casewalls, acoustic chambers, sound-treated rooms.

Purpose

Audiometers measure and characterize hearing loss by

determining an individual’s hearing threshold (the lowest

audible sound to which the individual will respond 50% of the

time) for pure tones and speech and then comparing that

threshold with a standard range of normal threshold values.

These normal audiometric threshold values represent the mean

lowest level at which a group of young adults can detect a

selected sound.

Hearing loss can result from lesions anywhere along the

auditory tract. When the outer and/or middle ear is affected, the hearing loss is termed conductive; when the

inner ear or auditory nerves are affected, it is termed sensorineural. Abnormal conditions that can cause a

conductive hearing loss include obstruction of the outer ear canal (e.g., foreign mass, swelling), neoplasms,

congenital malformation, perforated tympanic membrane, disruption or fixation of the ossicles (bones of the

middle ear), and fluid and scarring in the middle ear. Abnormal conditions that can cause a sensorineural hearing

loss include congenital malformation, head trauma, exposure to intense noise, drug-induced toxicity, genetic

factors, aging, infectious diseases, and neural tumors. Audiometry aids in diagnosis of otologic and/or neurologic

hearing loss and selection of therapy.

Pure-tone audiometry measures hearing sensitivity (hearing

threshold) for a series of single-frequency signals chosen from the

normal range of human hearing. Although this method can assess the

degree of hearing loss, it cannot characterize the extent of impaired

speech discrimination (understanding of speech). Speech audiometry

measures hearing sensitivity for spoken material. In addition, spoken

material can be used to test for speech discrimination.

Audiometric booths provide a consistent and controlled acoustic environment and keep background noise at

an acceptably low level to provide a suitable test area for clinical audiometry or research.

Principles of operation

Audiometers

In the normal ear, sound waves travel through air in the outer ear and cause bones in the middle ear to vibrate.The inner ear converts these mechanical vibrations to hydraulic energy and ultimately to neural impulses that are

transmitted along the auditory nerve to the brain, where it is perceived as sound.

When a patient has a suspected hearing loss, a physician may order an audiometric analysis; screening and

diagnostic testing are then directed by the audiologist. Baseline and annual screenings may be performed for

workers at risk of hearing loss from occupational noise exposure as part of a hearing conservation program and in

compliance with the Occupational Safety and Health Administration (OSHA) standards. The conventional

procedure for determining hearing threshold begins with familiarizing the patient with the stimulus. The test

proceeds according to a protocol recommended by the American Speech-Language-Hearing Association; the

protocol requires a fixed number of positive responses to stimuli (pure tones or speech) presented in sequences of

increasing intensity.

The weakest sound heard at a selected frequency is the hearing level in decibels (dB HL) for that particularfrequency. This is a relative value; the intensity reference is 0 dB HL, or audiometric 0, which corresponds to the

average threshold response of a group of 18- to 25-year-olds with no otologic pathology. The sensitivity of the

normal ear varies with frequency; therefore, 0 dB HL represents different levels of sound pressure at different

frequencies. (Negative dB HL readings indicate that hearing sensitivity is greater than normal at that p articular

frequency.)

Pure-tone audiometers typically generate a series of frequencies between 125 and 8,000 Hz, depending on the

type of test and audiometer. The American National Standards Institute (ANSI) specifies a number of categories

of audiometers based on the range of frequencies, sound-pressure levels, and testing capabilities available.

In a pure-tone audiometer, single-frequency tones are produced by an audio oscillator. An attenuator control is

used to adjust the intensity changes within a specified range, typically from 0 to 90 dB HL. Signals can be

delivered in a continuous or pulsed (interrupted) mode; pulsed tones appear to be more useful when testing

children or patients with tinnitus (ringing in the ear). Microprocessor-based units give the examiner the option of

delivering the signal manually or automatically, using a programmed presentation sequence. The examiner

directs the signal to earphones or to a bone-conduction vibrator. The patient may use hand signals or a

handswitch to respond to a tone that has been heard. Both air- and bone-conduction pure-tone testing must be

performed to determine whether hearing loss is conductive, sensorineural, or both.

Pure tones are directed to earphones to test air-

conduction hearing, which relies on the action of the

outer, middle, and inner ear and neural pathways. The

electrical signal from the audiometer is transformed

into vibrations within an earphone’s diaphragm that

generate a sound of a frequency and amplitude (dB)proportional to the electrical signal. The examiner can

test the left ear, right ear, or both. The threshold search

protocol is performed for a fixed series of frequencies

in each ear. Results are recorded in a graphic and/or

tabular format called an audiogram (see Figure 1).

Bone-conduction hearing relies solely on the action

of the inner ear and neural pathways. Pure tones are

directed to a bone-conduction vibrator placed on the

forehead or the mastoid process behind the ear. The

electrical signal from the audiometer creates

vibrations within a plastic shell in the vibrator. As the

vibrations are transferred to the skull, the inner ear is

stimulated directly as a result of bone distortion and

indirectly as a result of inputs received from outer-

and middle-ear vibrations. Some instruments record

air- and bone-conduction data on the same graph or

table, while others show the data on separate audiograms.

The procedure for bone-conduction testing is basically the same as that for air-conduction testing. Ideally, both

should be performed in an audiometric booth; however, when this kind of room is unavailable, testing should be

performed in quiet surroundings with minimal background noise. Some instruments feature a two-way

microphone built into the earphone headset to permit communication between the patient and the examiner

when the patient is isolated in an audiometric booth.

In conductive hearing loss, air-conduction thresholds

are higher (indicating more hearing loss) than bone-

conduction thresholds. In sensorineural hearing loss,

both air- and bone-conduction thresholds are equal and

elevated (hearing is below normal). When hearing loss

is “mixed” (both conductive and sensorineural), air- and

bone-conduction thresholds are again elevated;

however, air-conduction thresholds are higher than

bone-conduction thresholds. Bone-conduction testing is

sometimes used in lieu of air-conduction testing for

young children, when reliable pure-tone thresholds

cannot be obtained.Speech audiometry measures the sound levels at

which speech is detected and individual words are

distinguished from one another. Spoken material is

introduced as an input signal to the audiometer from a

microphone, phonograph, tape recorder, or compact

disc (CD). The signal is intensified in an amplifier and

monitored by a volume-units meter. Intensity range is

calibrated in dB HL and is controlled with an attenuator

as in pure-tone audiometry. The examiner directs the signal to earphones or through a second amplifier to

loudspeakers. An ear-selector control may also be used to direct the signal to the left or right earphone only.

Most testing is done through air-conduction

earphones. Sensitivity for speech is determined using a

speech-reception threshold (SRT) test. Threshold search

protocols are similar to those used for pure-toneaudiometry. The second component of speech

audiometry is the speech-discrimination test (SDT),

which assesses the patient’s ability to understand

monosyllabic words at suprathreshold (above

threshold) intensities. Patients with severe inner ear

disease cannot distinguish between similar words, even

at these high sound levels.

When earphones are not practical (e.g., when young

children are being tested), free-field testing is used. The

patient is placed equidistant between two loudspeakers

in a sound-isolation room. Warble tones (tones with

specific modulation rates), narrow-band noise (tones of

several frequencies of equal intensity), or spoken material is used as the auditory signal.

The shape of audiometric curves can be very useful in diagnosing certain types of hearing loss when other

methods of clinical and laboratory analysis are unsuccessful. For example, patients with hereditary dominant

mid- and low-frequency sensorineural loss show no evidence of pathology aside from their characteristic

audiograms (see Figure 2). Audiometric testing of siblings provides confirmation of this diagnosis.

When the nontest ear is suspected of responding to the test signal, it must be masked. One of three types of

masking is applied to the earphone corresponding to the nontest ear: white noise, pink noise, or narrow-band

noise. White noise consists of a wide range of frequencies with uniform loudness and is used to mask tones or

speech. Pink noise is similar to white noise except that it consists of a higher proportion of lower frequencies and

is used to mask speech alone. Narrow-band noise consists only of frequencies close to the ones being tested and is

used to mask pure tones. Proper application of masking is complex, especially when the hearing loss is mixed or

if only one ear has a severe sensorineural loss. Masking intensity is usually quantified in decibels sound-pressure

level (dB SPL).

Audiometric booths

The walls of audiometric booths consist of steel panels on the outside, sound-absorbing perforated steel panels

on the inside, and an incombustible acoustic insulating material (e.g., fiberglass) in between.

Single-wall booths are constructed from a single wall and a layer of sound-absorbing material and are used

primarily for pure-tone air-conduction testing. Double-wall booths employ “booth inside a booth” construction

in which the walls of the inner examination booth are separated from the outer panels by an air space; this design

further reduces outside noise interference and is preferred for bone-conduction, sound-field, and speech testing.Single- or double-wall construction can be used in both single- and double-room configurations.

Single-room booths (see Figure 3) isolate the subject from the environment, but not the examiner. Most

audiometry can be performed in a single-room booth; the exception is live-voice speech testing. Double-room

booths (see Figure 4) consist of two connecting rooms (a control room and an exam room) that isolate the

examiner and subject from the environment and also from each other. Either a single or double wall (depending

on the booth construction) separates the two rooms and incorporates a window consisting of several layers of

glass. Windows should provide visual contact between examiner and subject but obscure the subject’s view of

any distracting activities in the control room. Windows are also present in the walls of a single-room booth and

may be present in the external walls of a double-room booth to allow the inside of the booth to be viewed from

the outside.

Single-wall booths have one door, which opens outward; double-wall booths have a second door, which opens

inward and is mounted on the same frame. Some double-room configurations offer an optional single or double

door between the control and test rooms. Vibration isolators underneath the booth minimize floor vibrations and

sound transmission. A specially designed forced-air system can minimize ventilation noise.Portable booths are single-wall structures and move on locking casters. They may also come with vibration

isolators and ventilation systems. Larger, nonportable booths come in kits that include prewired wall, floor, and

roof sections; wall and corner joiners; acoustic filling material; and a ventilation system—many portable booths

come completely assembled. Some smaller portable booths are designed to be disassembled for transport from

one testing location to another.

Reported problems

Reliable audiometric measurement depends on equipment calibration, the test environment, patient

cooperation, and examiner performance. All audiometric equipment must be calibrated according to international

standards. However, calibration and test results are invalid if the test is not performed in the proper environment.

Background noise levels must not exceed those prescribed by organizations such as ANSI and OSHA, and visualdistractions, ventilation, and temperature must be controlled. Finally, the room should be set up so that the

patient cannot see what the examiner is doing with the audiometer while the test is being performed.

ECRI Institute has received no reports of safety problems unique to audiometric booths. Single-wall booths can

be constructed of optional fireproof panels and doors; the inner panels and doors of double-wall booths can also

be made of fireproof material.

Purchase considerations

ECRI Institute recommendations

The accompanying comparison charts include ECRI Institute’s recommendations for minimum performancerequirements for audiometers. The recommended specifications have been divided into two categories:

audiometers used for screening purposes and audiometers used in clinical environments. Each of these categories

is further broken down into two subcategories—one for minimum requirements based on ANSI S3.6-1996, which

will provide the user with a basic audiometer, and the other for recommendations intended for more advanced

functions. These recommendations will be most appropriate for users who commonly perform comprehensive

studies. (See ANSI type designations.)

Screening audiometers should be type 4 as described in ANSI 3.6-1996. Audiometers with these capabilities

should provide the user with all necessary functions to perform under most screening conditions. Selecting a unit

with greater capability may result in more difficult operation and/or higher costs. Ease of operation is important,

particularly in screening programs in which operators may have minimal training and experience. Screening

programs generally do not use speech audiometry, and OSHA does not require it for annual audiograms;

therefore, this feature is not recommended for audiometers used for screening purposes. For screening, pure-tone

audiometers, at minimum, should be capable of testing at frequencies of 500 to 6,000 Hz.

Audiometers used for clinical testing and diagnosis should be at least type 3 as specified by ANSI S3.6-1996.

Type 1 audiometers may be required under certain conditions and are recommended for clinical environments in

which a full range of testing applications must be met. Clinical audiometers may also require speech-testing

capabilities. For this purpose, the audiometer should be designated at least type C. Standardized, specially

prepared speech material from tape or CD input is preferred to microphone input. This ensures consistent testing

and results among subjects.

Standard clinical audiometry testing is performed over a range of 250 to 8,000 Hz. OSHA does not require

bone-conduction testing for annual or baseline audiograms; however, it can be useful in determining diagnosis

(e.g., discovering where a hearing problem may lie) in a clinical setting. For most testing, frequency accuracy

should be within 3%; accuracy within 1% is recommended for some clinical applications. It is also recommended

that half-octave or octave steps be available for both clinical and screening applications. Testing at half-octave

frequencies is often used to verify that the subject’s hearing level does not change significantly within an octave.

Masking noise should be available for clinical testing to ensure that one ear is not compensating for the other

during the test.

Certain considerations for earphones

must be made for any type of audiometric

testing. Those used to deliver the signal to

the subject should include one earphone for

each ear. Although supra-aural earphones

are commonly used, availability of insert

earphones is advantageous, since these

earphones are generally lighter and provide

a better fit than supra-aural earphones. They

also offer greater protection against the

signal being heard by the opposite ear. Free-

field testing is not normally recommended

for screening purposes. However, they are a

good alternative to earphones when testing

small children who may not tolerate

earphones. Free-field testing is also used in

certain hearing-aid assessments.

Earphones should be in proper condition: pads should be soft, pliable, and free of cracks. Cords should also be

checked to make sure that the left and right earphones are connected to the correct earjacks. Earphones should be

calibrated for use with the audiometer to produce the required sound-pressure levels.

Audiometric booth requirements depend on individual circumstances. In some cases, testing may be

performed without a booth; however, when the test area is too noisy, a booth is required. Industry standards for

noise levels should be considered. The amount of sound reduction required will depend on the noise level in the

area, taking into account the noisiest periods of time. Other booth requirements will also depend on individual

circumstances. Size requirements depend on the available space, but the booth should be able to comfortably

accommodate the subject, the examiner, and all necessary equipment. In audiometric booths with two rooms,

there must be a window between the rooms.

Booths with fluorescent lighting must have the light’s starter mounted on the outside of the examination room

because starters produce a hum that may interfere with testing. In addition, windows must have moisture-

absorbing materials between the panes to prevent fogging. If the booth has a step, a ramp must be provided for

subjects in wheelchairs or on stretchers. Because doors must be solid and close with an acoustic seal, they are

often very heavy.

Other considerations

Some audiometers feature software that assesses the hearing level by comparing it to age-related values from

the general population. Software is available that allows the user to design a format that can accommodate a large

amount of patient (and company) data or to customize test protocols to fit the individual patient’s needs and

capabilities. Some audiometers provide a graphic output of results for threshold testing, and several units can

store a limited number of audiograms in nonvolatile memory.

Multichannel audiometers are available that can examine several people at once. Each channel of a group

audiometer is programmed to administer a complete series of tests to each individual; all channels are linked to a

central control channel through which the examiner can set the test parameters and initiate testing. Special

software programs compare the individual’s hearing threshold to a normal range of values (adjusted for age and

exposure to noise)—for example, from an employee’s occupational group. (Many companies require their

employees to undergo regular audiometric testing as part of a hearing-conservation program. Multichannelaudiometers enable companies to perform time- and cost-effective on-site testing of the workforce.)

Various suppliers include optional parts such as external power amplifiers, computer cables, microphones,

software, memory cards, and service manuals. Check to see if the warranty includes a hotline service for any

technical problems and/or user difficulty.

Stage of development

Microprocessor-based units have automated most test procedures and hearing-threshold calculations. Certain

computerized units have validity checks within their operational programs that repeat the signal for a given

frequency and compare the two responses. Personal-computer-based audiometers that can be used with

notebook, desktop, or networked systems are also available. These systems may have features such as graphical

displays of results, warnings, and referral levels; use of disk drives for storage; and connection to a printer toobtain additional records.

Tympanometers, middle-ear analyzers, and auditory-evoked response units have been developed that test

certain parts of the ear and auditory nerve to gather more specific information about the nature of a hearing

problem. More sensitive and specialized tests have been created for these instruments to enhance diagnosis and

monitor the results of rehabilitative therapy.

Audiometric booths are a widely accepted component of the instrumentation used in clinical diagnosis of

hearing disorders. There have been no recent changes in the technology of these rooms, and none are foreseeable

in the near future.

Policy Statement

The Healthcare Product Comparison System (HPCS) is published by ECRI Institute, a nonprofit organization.

HPCS provides comprehensive information to help healthcare professionals select and purchase diagnostic and

therapeutic capital equipment more effectively in support of improved patient care.

The information in Product Comparisons comes from a number of sources: medical and biomedical

engineering literature, correspondence and discussion with manufacturers and distributors, specifications from

product literature, and ECRI Institute’s Problem Reporting System. While these data are reviewed by qualified

health professionals, they have not been tested by ECRI Institute’s clinical and engineering personnel and are

largely unconfirmed. The Healthcare Product Comparison System and ECRI Institute are not responsible for the

quality or validity of information derived from outside sources or for any adverse consequences of acting on such

information.

The appearance or listing of any item, or the use of a photograph thereof, in the Healthcare Product Comparison

System does not constitute the endorsement or approval of the product’s quality, performance, or value, or of

claims made for it by the manufacturer. The information and photographs published in Product Comparisons

appear at no charge to manufacturers.

Many of the words or model descriptions appearing in the Healthcare Product Comparison System are

proprietary names (e.g., trademarks), even though no reference to this fact may be made. The appearance of any

name without designation as proprietary should not be regarded as a representation that is not the subject of

proprietary rights.

ECRI Institute respects and is impartial to all ethical medical device companies and practices. The Healthcare

Product Comparison System accepts no advertising and has no obligations to any commercial interests. ECRI

Institute and its employees accept no royalties, gifts, finder’s fees, or commissions from the medical device

industry, nor do they own stock in medical device companies. Employees engage in no private consulting work

for the medical device industry.

About ECRI Institute

ECRI Institute, a nonprofit organization, dedicates itself to bringing the discipline of applied scientific research

in healthcare to uncover the best approaches to improving patient care. As pioneers in this science for nearly 40

years, ECRI Institute marries experience and independence with the objectivity of evidence-based research.

More than 5,000 healthcare organizations worldwide rely on ECRI Institute’s expertise in patient safety

improvement, risk and quality management, healthcare processes, devices, procedures, and drug technology.

ECRI Institute is one of only a handful of organizations designated as both a Collaborating Center of the World

Health Organization and an Evidence-based Practice Center by the U.S. Agency for Healthcare Research and

Quality. For more information, visit http://www.ecri.org.
