A Sound Idea
Photos of the Month — August 2014
Did you know that August is Audio Appreciation Month? From the photophone to the iPhone, the way we communicate seems to evolve as fast as the speed of sound. With the Acoustical Society of America being one of AIP’s 10 membership organizations, we thought we'd take a moment to highlight innovations made in the field of acoustical physics. Our six featured images span from Bell Laboratories' Oscar II to present-day inventions like the Electret Microphone. These and many more images can be found on this site. Please enjoy this featured selection from our historical photos collection. To see more images like the ones we’ve selected, type the word "sound" in the search engine.
