Thanks for the addition information, ZCT. I have always been bothered by loud noises. I guess I just assumed everyone was.
I go back in for adjustments next Thursday. I’ll report back afterwards.
Audiogal, thank you for your input also.
I found this K-AMP information at Etymotic Research, Inc.: http://www.etymotic.com/ha/kamp-faq.aspx
I think this information is about 5 years old so things may of changed since then.
Frequently Asked Questions
Q What Do K-AMP Hearing Aids Do?
A K-AMP circuits offer level-dependent progressive frequency response (greater treble boost for quiet sounds). When the K-AMP circuit was introduced in 1989, it was (and still is) the only amplifier that combines wide dynamic range compression (WDRC) with the following features: Variable recovery time which provides instant recovery from hand claps and door slams, and slow recovery for normal sounds to eliminate pumping.
A single-channel circuit that performs like a multi-band compressor. In the original K-AMP circuit (TILL version) there is a compression ratio of 1.3:1 in the low frequencies and a compression ratio of 2.1:1 in the highs. The programmable K-AMP can be programmed up to 3:1 in the highs.
Clean, undistorted operation even at inputs up to 110 dB SPL. At 90 dB SPL input, the K-AMP has essentially zero-noise and zero-distortion out to 13 kHz (a coherence of 1.0). No other circuit can make this claim.
Q What Is The Difference Between K-AMP WDRC and Other WDRC?
A In order to determine how much gain to provide, all compressors require a level-detection circuit. The K-AMP uses rms detection, which provides a more accurate estimate of signal energy (loudness) than either peak detection or average detection used in other circuits.
