Assistive Listening Devices (ALDs)

Phonic Ear Model PE300 "Easy Listener" FM System

The Phonic Ear Model PE300 "Easy Listener" FM system was made by Phonic Ear A/S of Denmark (USA office in Petaluma, CA) from 1994 (or perhaps a year or two earlier) and 2002 or so. (The Phonic Ear Easy Listener II came out in 2003.)

It consisted of a  wireless microphone  which the person speaking wore and the pager-like FM receiver which the hard of hearing person wore.

Phonic Ear systems were commonly used by schools for their hard of hearing students.

The Model PE300 transmitters and receivers each measured 3 11/16" x 2 3/16" x 1" (9.4 x 5.6  x 2.5 cm) and weighed 2.8 oz. (80 g).

This system worked in the 72 - 76 mHz band. The band was divided into 40 narrow-band FM frequencies. The number located in the bottom right corner of the transmitter (32) indicated this transmitter was set to transmit on frequency 32.

Close-up view of the actual boundary microphone located in the center of the cone of the optional Model AT 560-72-3 Conference Table boundary microphone. In use the cone was inverted (see above picture).

The boundary microphone "floated" 1/16" or so above the metal plate which "picked up" the sounds from the air and directed them to the microphone. This design was more sensitive to sounds than other microphones commonly used so worked very well in conference table type of settings.
