A recent blog post written by Dr. Sussman on Auditory Scene Analysis and Sound Processing was featured on Albert Einstein College of Medicine’s blog The Doctor’s Tablet.
Imagine yourself walking on a busy city street. Noises from the environment converge and digress as you walk: a jet flies overhead, a jackhammer makes repeated sound bursts, cars drive by, people are talking as they walk past you.
The sound waves reach your ears in a mixture of all the sources, overlapping and dynamically changing over time. Thus, the ability to listen to your friend talking while walking down a noisy city street requires brain mechanisms that disentangle the sound mixture, separating your friend’s voice from the sounds of the cars and other passing conversations, providing neural representations that maintain the integrity of the individual and distinct sound sources
