The secret is the very sophisticated, 100% digital DSP Amplifier. The DSP Amplifier is a very powerful computer that lets us program the hearing aid so that it is, in effect, many hearing aids in one.

First, the DSP Amplifier is programmed with an Adaptive Feedback Cancellation algorithm that eliminates those frequency signals that cause feedback and whistling. AFC enables you to utilize SD003 AFC's full potential 17dB gain (volume increase). Should the unit begin to feedback the computer senses the digital feedback pattern and cancels it within seconds. How loud you set the unit is now up to you and for most, the SD003 AFC provides more amplification power than you'll ever need. Just remember to take your finger away from your ear after setting the volume to give the computer program a second or two to adjust.

Next, we've programmed the SD003 AFC with two Pre-set memories. Memory 1 is for normal, everyday situations. Memory 2 is for noisy or loud situations like when you're out to dinner in a noisy restaurant. The pre-set memories let you determine what sounds are amplified and by how much based on the situation you're in. Simply, you hear the sounds you want to hear -- crisp, clean and clear.
