Re: Demos of hearing loss and amplification



Here is an audio clip i just made for you.

http://www.ambiophonie.ca/ARCH/2004/05/13/ClairePicheWindigoRiver.wav

The audio clip i sent to you is the recording (i made) of a river and
the duration is 1'35'' seconds

00:00'' to 00:15'' has no filtering
00:15'' to 00:20" frequencies higher than    10 KHz are filtered
00:20'' to 00:25'' frequencies higher than        5 KHz are filtered
00:25'' to 00:30'' frequencies higher than   2,5 KHz are filtered
00:30'' to 00:35'' frequencies higher than   1,3 KHz are filtered
00:35'' to 00:40'' frequencies higher than  640 Hz are filtered
00:40'' to 00:45'' frequencies higher than  320 Hz are filtered
00:45'' to 00:50'' frequencies higher than  160 Hz are filtered
00:50'' to 00:55'' frequencies higher than  320 Hz are filtered
00:55'' to 01:00'' frequencies higher than  640 Hz are filtered
01:00'' to 01:05'' frequencies higher than   1,3 KHz are filtered
01:05'' to 01:10'' frequencies higher than   2,5 KHz are filtered
01:10'' to 01:15'' frequencies higher than      5 KHz are filtered
01:15'' to 01:20" frequencies higher than    10 KHz are filtered
01:20'' to 01:35'' has no filtering

Free of compression during the wild recording nor when i transfered it
to the computer.
No augmentation or diminution of the output gain during the filtering.

i'm looking forward to hearing from you

A large charity in the UK, the RNID, has asked for the following. Can anyone
help? Thanks!

We're looking (urgently) for some sound clips that demonstrate the effect of
hearing loss and amplification for a big forthcoming exhibition.  We are
familiar with Brian Moore's CD of course but wondered if you know of
anything else - especially anything that would be particularly suited for
demo use?
