Compressed Babble – for speech-in-noise testing

Here are 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.
