Information About Digital Hearing Aids
In a digital hearing aid, the analog signal is converted to a digital signal. The conversion to digital format allows the signal processor to modify the signal in very sophisticated ways. Once the digital signal has been modified by the digital signal processor it is converted back to an analog format and transmitted to the ear as sound.
The digitization process makes it possible to analyze and filter the signal to improve speech perception in noisy environments. The incoming signal is measured, or "sampled," at certain intervals. The more frequently the signal is sampled, the better the reproduction of the input signal.
Increasingly complex sound processing, such as speech recognition technology, requires digital signal processing. This technology actually recognizes the unique patterns of speech and reduces the volume of frequencies where no speech is detected. When the competing signal is continuous noise, such as fans or car noise, the noise reduction algorithms become an important part of the signal processing that improves understanding. There are varying levels of this technology suitable for individual lifestyle and budget needs.
