The tiny microphones used inside hearing aids can be very sensitive to vibration of the device, resulting in annoying feedback. Testing how sensitive these microphones are to vibration has been a problem that plagued engineers. In this episode, we talk to Charles King and Chris Monti of Knowles Electronics about their innovation to measure microphone vibration sensitivity.

Speech Science courses are a key component to the curriculum within a variety of disciplines, but coursework is frequently lacking in terms of representation of those from different cultural and linguistic backgrounds. In this episode, we talk to Melissa Baese-Berk (University of Chicago) and Paul Reed (University of Alabama), about why it's so important for instructors to use a variety of voices in the classroom, and how to talk about other ways of speaking when one feels ill-equipped to do so.

In the aftermath of World War II, New York City wanted to built a new home for its orchestra, the New York Philharmonic, and secure its place a cultural center of the world. In this episode, we talk to the Paul H. Scarbrough (Akustiks, LLC) about where these plans went awry and the multiple renovations over many decades to fix the hall.
