Bathurst room treatement video - measurements

Here are the measurements that go with the video demonstration at Bathurst of acoustic treatment.

Frequency response:

Untreated: red
Treated: grey

You can see the bass range is similar, but in the midrange we see more differences due to the treatment.

Unsmoothed version:



Untreated: red
Treated: grey

Below 200 Hz (smoothed)



Untreated: red
Treated: grey

 Perhaps the most interesting result is the reverb time:





Untreated: red
Treated: grey

In the untreatd room, the reverb is quite high, with an average above 0.7s and this drops off at higher frequencies. In the treated room, the reverb time is more flat, and averages around 0.32 s. 

By 100 Hz, both rooms are similar in reverb as the treatment is midrange focused.
