| Circuits: |
Linear
Works well in a relatively quiet environment. Oldest type
of circuitry available. They are helpful for one-on-one conversation and television
listening. Includes Class D or push-pull circuitry. |
Single Channel Compression
Performs better than linear circuits in loud or noisy
environments. Limits sounds from becoming too loud without the distortion of linear
technology. Includes the ASP, AGC-I, AGC-O, Adaptive Compression, K-Amp, or Super
Compression circuits. |
Multiple Band Programmable
Programmed with a computer to individual needs. Advanced
curvilinear compression with adjustable characteristics for better control over background
noise. Multiple settings are available for different listening situations. |
100% Digital Sound Processing
Offers the latest advances in hearing aid technology.
Sound processing similar to CD quality. No volume control to adjust. Can automatically
detect and reduce non-speech background noise. Twin microphone options can reduce the
level of sound from behind you making it easier to hear speech from in front. |
