Virtual instrument for testing the hearing impaired
Karl H. Norian · Review of Scientific Instruments · 2001
LABVIEW programing was used to build a virtual instrument to assess the needs of individual hearing impaired subjects to enable them to hear speech in background noise. The instrument acquires the noisy speech, adaptively removes noise from speech, and then feeds the speech to the subject. Design changes can quickly and easily be made to the instrument to assess the specific requirements of the electronic circuit of the hearing aid for the individual subject. The instrument provides a novel way of providing custom electronics for hearing aids.
