Digital hearing aids were introduced twenty-eight years before but their popularity has been since the last few years. Now, there are a number of digital hearing aids manufacturers.
When these aids were first introduced, only two manufacturers were there. They made the devices with digital signal processing but these devices were highly successful and were abandoned because of their high battery drainage system and big size. After a decade, again two other manufacturers introduced a different kind of digital aid with an improved technology and style from completely-in-the-canal to behind-the-ear.
The improved digital hearing aids introduced were available at a high cost but despite their high price, they were received well by consumers and clinicians. They have substituted analog devices today and are dominating the hearing aid market. While the newer ones are not always better but a closer look shows that these devices beat the analogs in both function as well as form.
What is it that actually makes a hearing aid digital? The analog hearing aids generally take the sounds and make it louder. Some of the aids include a microchip but the functions of it are basic. On other hand, digital hearing aids take in the sound waves, translate it into the digital format, process it, do filtration, distort it, amplify it and finally deliver a sound signal into the ear canal, which is tailor-made to the needs.
So, are these digital ones really superior to the analogs? For determining whether the digital gearing aids are really better for the patients, it’s essential to concentrate on the better processing and the features of the instruments.
These devices are not a completely different entity from an analog hearing aid. The word ‘digital’ actually indicates that analog waveform is basically converted into string of numbers to process. However, there isn’t anything magical about this method. The speech recognition and sound quality of digital hearing aids is much better than the analog devices. Thus, digital is not only superior because it is digital but because the digital signal processing enables the manufacturers to make these devices with an enhanced processing as well as features.
