Question

[ b) The time of reverberation of an empty hall without and with 500 audiences is 1.5 sec and 1.4 sec respectively. Find the reverberation time with 800 audiences. Wait​

Answer 1

The reverberation time with 800 audiences is 0.875 seconds.

Reverberation time with 800 audience

R₁V₁ = R₂V₂

where;

• R₁ is the reverberation time with 400 audience
• R₂ is the reverberation time with 800 audience
• V₁ is initial volume
• V₂ is final volume

R₂ = R₁V₁/V₂

R₂ = (1.4 x 500) / 800

R₂ = 0.875 seconds

Thus, the reverberation time with 800 audiences is 0.875 seconds.
