What’s the difference between analog and digital hearing aids? Analog hearing aids basically take sounds and make them louder, just as cupping your hand behind your ear amplifies sound. Some analog hearing aids include a programmable microchip, but the functions are relatively basic. Digital hearing aids take in sound waves (in themselves, analog signals, for the tech folks out there), translate them into digital format, process, filter, distort, amplify and ultimately deliver a sound signal into your ear canal that is custom-tailored to your needs. In order to perform all these wonders, digital hearing aids contain a Digital Signal Processor (DSP) chip. To better understand digital versus analog, consider the difference between analog vinyl records and digital CDs. Vinyl records require fairly simple methods for playback, and a simple turntable and needle will do the trick. CDs take a little more hardware, as the digital information has to be processed and reproduced. While there is a greater amount to do, CDs provide clearer, high fidelity sound. Some people prefer the warm crackle of a vinyl record, but that fuzz simply won’t do when it comes to your hearing!
Hearing aid styles Hearing aids vary a great deal in price, size, special features and the way they're placed in your ear. The following are common hearing aid styles, beginning with the smallest, least visible in the ear. Hearing aid designers keep making smaller hearing aids to meet the demand for a hearing aid that is not very noticeable.
Open-fit hearing aid is a variation of the behind-the-ear hearing aid with a thin tube. This style keeps the ear canal very open, allowing for low-frequency sounds to enter the ear naturally and for high-frequency sounds to be amplified through the hearing aid. This makes the style a good choice for people with mild to moderate hearing loss. An open-fit hearing aid: Is less visible Doesn't plug the ear like the small in-the-canal hearing aids do, making your own voice sound better to you May be more difficult to handle and adjust due to small part
Completely-in-canal (CIC) hearing aids are the smallest type of hearing aids choices. These hearing aids have good cosmetic appeal and are different from others as they are custom fitted to the inside of your ear canal to amplify sounds in individuals with mild to moderately severe hearing loss.
According to Action on Hearing Loss around 1 in 6 people have some degree of hearing loss.The majority of people with hearing loss rely on hearing aids to improve their hearing. About 70% of hearing aid wearers have hearing loss in the “mild-to-moderate” range. Many of the remaining 30% have hearing loss that falls into the “severe-to-profound” category.
