Sound absorption test results. The graphs display the spectrum of the signals recorded by the microphones inside the box with both box doors open (blue), with just the insight box door closed (orange) and with the anechoic box fully closed (green) when a sine sweep sound from 20 Hz to 20 kHz was played outside the box from a speaker.
