Museum of Portable Sound

US acoustician, MIT professor & inventor Leo Beranek using a Hush-A-Phone, a device for silencing phone calls. AT&T, who held a over US service at the time sued against the device & lost, setting a legal precedent that eventually led to their own breakup.

Black and white photo of an elderly white man in large plastic-framed eyeglasses holding an old-school telephone receiver up to his ear. The speaking end of the phone is encased in a large black plastic chamber that also covers the man's mouth. The spiral-shaped phone cord juts out of a hole in the side of the black plastic chamber, the Hush-a-Phone.
