    Step 1: Rigid body model of vibrating transmission

  • ⓒ FunctionBay, Inc.3

    Step 2: Use RFlex to model flexible housing

  • ⓒ FunctionBay, Inc.4

    Step 3: Calculate ERP (Equivalent Radiated Power)

    Equivalent Radiated Power is a measure of sound emission for a surface.

    𝐸𝑅𝑃 = 𝑅𝐿𝐹 ×1

    2× 𝐶 × 𝜌 × 𝐴𝑖 × 𝑉𝑖

    2

    RLF: Radiation Loss Factor

    C: Sound Velocity

    ρ: Air Density

    𝐴𝑖: Surface Area of Each Element𝑉𝑖: Normal Velocity of Each Element
