    SVAN 977C User Manual - Appendixes APPENDIX E. REVERBERATION TIME CALCULATIONS E.1. I NTRODUCTION If an impulsive sound is generated in a room with reflecting boundaries, repeated reflections at the boundaries result in the rapid establishment of a more or less uniform sound field. This field then decays as the sound energy is absorbed by the bounding materials.

    SVAN 977C User Manual - Appendixes reverberation time (RT 60) is obtained using the slope coefficient of the decay curve. The type of the definition from which slope coefficient is calculated (EDT, RT 20, RT 30 or user defined) depends on the difference between levels L and L (the difference between background noise level and sound source...
  • Page 331 SVAN 977C User Manual - Appendixes It is recommended by the ISO-3382 standard to set 10 dB value for noise margin. In case of the impulse method, the sound pressure level values between points t and t are approximated with the straight line (y = a · x + b) by the linear regression. The RT 20 value is calculated using the slope coefficient ‘a’...
