In June of 2015, Acoustics First® posted about our experiment which allowed people to hear the effects of sound diffusers in a small space. The experiment consisted of treating a small office with varying numbers of our new (at the time) Art Diffusor® Model D sound diffusers, then providing various sonic stimuli and capturing and measuring the results with a custom binaural head (called “Binaural Bob.”) This experiment received great feedback and with that input, future experiments were conducted using a similar method, mixing absorbers and diffusers, and having a wider range of stimuli.

But here we look back to the first… This is the video we produced during that experiment way back in 2015 with Binaural Bob, a bunch of Model D’s, a small office, some balloons, bang snaps, and one very heavy book.
