Besides his work on the electret microphone, in what other area of acoustics did James E. West conduct research?

Answer

Sonar technology and underwater acoustics

James E. West did not limit his research solely to the electret microphone or consumer electronics. His extensive work at Bell Laboratories included significant investigations into sonar technology and other applications of underwater acoustics. This diversification demonstrates his approach to engineering, where he applied fundamental acoustic principles across various practical domains rather than specializing in a single, narrow area of technology.
