SVAN 977A 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.

Page 299 SVAN 977A 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’...
