HearSource Software 12 Band Equalizer
The HearSource hearing aid programming software gives extreme flexibilty in adjusting frequencies. The FreeStyle OE BTE, Symphron BTE, and the Jazzy ITC all have a 12 band equalizer associated to their ciruit models. This allows the user to adjust their hearing aids with their own PC. The range of frequencies that can be adjusted is from 250Hz to 8kHz. This is the range for speech and communication. If you look at figure 1-A you can see the 12 band equalizer.
**Note the frequency labels above and below the frequency sliders are not in the HearSource programming software. In the software if the cursor is hovered over the frequency slider nub it will identify the frequency.
To adjust the frequencies take the mouse cursor and click/hold the frequency slider nub and move up or down. Also by clicking above or below the frequency slider nub it will move the nub in the direction clicked by 1 hash mark.
Each hash mark on the frequency sliders is worth 3 dB. This is important to know because it doesn’t take but a slight adjustment up or down to make a big difference in the sound settings in the hearing aid.
In another post we will go over how to adjust the 12 band equalizer for desired effects. Some examples are;
voice sounds hollow
speech not clear
S, CH, sounds to sharp
