Using your rectangular room from Homework #$2(35ft65ft)$ add an $20$ ft ceiling height. Apply the following

materials onto the surfaces and determine the Reverberation Time per frequency band.

Variables & Equations:

$V=$ Volume ;

$S=$ Surface area;

$R{T}_{\text{b}\text{a}\text{n}\text{d}{?}_{(}()()N)}=\frac{0\mathrm{.}05(V)}{{\displaystyle \underset{?}{\overset{?}{}}}{A}_{\text{b}\text{a}\text{n}\text{d}{?}_{(}()()N)}}[ft]$

$=$ absorption coefficient

RESULTS

Now, change out two walls $($one long, one short$)$ and the ceiling to the following materials listed below and

determine the new Reverberation Time.

RESULTS

Questions:

What do you observe between the two rooms?
