The following comments have been made by those who have purchased
or used AUDIO-CD.
" DIGITAL RECORDINGS' new CD the "AUDIO-CD" is a brilliant step forward
...."AUDIO-CD" is extraordinary and a most ingenious solution to making
universal hearing testing cheap, reliable and effective....It makes the
testing of hearing a simple home project which can be to the benefit of
many people who suffer from partial hearing loss due to noise in the
workplace or very loud music during their recreation. DIGITAL RECORDINGS
is to be congratulated on taking advantage of modern technology in this
ingenious way."
Prof.Hugh Jones, H.W. Jones and Assoc., England
" The quality of the stimuli is very good and the procedure to find
HTs is very clever (my colleague - Dr. Brad McPherson - used the
word 'ingenious'). Clearly, given the limitations of testing someone's
hearing on his/her own hi-fi at home, it would have been very difficult
to find an easier procedure to use."
Dr.Valter Ciocca, University
of Hong Kong, Hong Kong
" I was playing with your CD last night and I am very impressed by it...
it is the rare opportunity for everyone, to become active participant
of hi-tech development process, instead of being a passive consumer."
Dr.Nikalai Maltsev, Instrumar Ltd., Canada
" This AUDIO-CD is based on solid research work and uses many clever
ideas allowing to make testing both very accurate and very easy."
Dr.Bozena Kostek, Technical University of Gdansk,
Poland
"We just received your AUDIO-CD. My colleague - Erik Eknes - has a lot
of experience with hearing threshold testing. And he was very skeptical.
But after having tested your CD he is now very enthusiastic ! "
Dr.Rolf Kahrs Hansen, OmniTech AS, Norway
" I am very impressed by your work .........The kind of test signals you
chose seems very well suited for this test! Results between 100Hz and
10kHz were very well reproducible (+-1dB). All in all I find this a very
good product and congratulate you for this development."
Dr.Martin Opitz, AKG, Austria
