How Amazon engineers keep inventing from home

Working from home means something different to everyone. For our engineers, replicating physical lab spaces at home required quick ingenuity, a few household hacks, and lots of experimentation.

Brandon, an audio hardware engineer, created a pseudo-anechoic chamber in the bedroom of his house. It is made up of acoustic foam and Rockwool panels that are glued to cardboard backing and wrapped in speaker grill fabric to minimize wall reflections.

William, a hardware engineer, created a “Small Device Anechoic Chamber,” or what has become known as the “Anechoigloo.” To characterize the acoustic performance of small devices, the test chamber is outfitted with a layer of fiberglass acoustic damping material to provide an echo-less test environment.

Alex created an outdoor speaker measurement environment to continue his acoustics measurements while working from home. He was able to turn his daughter’s backyard zip-line into a speaker measurement rig to test loudspeakers.
