Compressed Babble – for speech-in-noise testing
An audio CD containing recordings of children’s background chatter, compressed to give a constant level for the 5-minute duration of each track. There are 9 tracks, each one 5dB above the previous track. Delivered via an amplifier and speaker(s) it removes the need for a 2-channel audiometer – simply play track 5, calibrate with a sound level meter for 70dB and all other levels can be presented by playing the appropriate track.
Listening Through Hearing Aids In Mainstream Classrooms
An audio CD which will help teachers of hearing impaired children in their work with mainstream colleagues and parents. It shows how distance from the teacher, combined with noise, make listening more difficult for the hearing aid wearer in a mainstream classroom, and underlines the value of the radio aid. All recordings were made through actual hearing aids and radio systems and incorporate the inherent distortions generated by such systems.
