What Different Types of Hearing Aid Technology are Available today

Present-day hearing aid technology covers a varied range of products and are commonly classified as being either analogue or digital. Inside these categories, differing devices can vary depending on size, shape, and how they are will be worn. In some cases, there are also some specialist devices for people in certain situations.

The classic analogue hearing aid merely amplifies sound. It achieves this by transforming sound waves into an electrical signal, which is then amplified and transmitted directly into the ear. While these are the cheaper option, such devices are to some extent limited and not really that responsive in many different situations.

Digital

There are now different types of hearing aid technology available today which are of the digital kind. This means that the hearing aid has a miniature computer inside which is capable not only of amplifying sound, but of evaluating and then processing it. The great benefit of this is that it means the hearing aid can be tailor tweaked to certain situations.

The amplification level of digital hearing aid technology can be programmed to meet the specific requirements of the user. Most models, then allow the amplification to be adjusted in different settings as diverse as a silent room or a loud concert. The settings, even allow alterations for various sized rooms, which gives the user a much better sense of a sound’s location.

Wearing the Hearing Aid

Such hearing aid technology is available for wearing in a number of ways. They can be worn behind the ear, inside the ear itself, or nowadays even completely hidden inside the ear canal. These invisible hearing aids in London, have become popular over time and are usually suitable only for less severe hearing loss. Some people suffer from what is known as “conductive hearing loss”, which means that their ear cannot transmit any sound waves. Hearing aids for these people usually work by delivering sound through vibrations.

Some other people are limited to having hearing in one ear only and have to use a type of hearing aid known as CROS. This obtains sound from the ear without hearing and transfers it to the ear with hearing, so that the user can handle all the sounds normally. People without any hearing in one ear and partial hearing in the other, can use BiCROS hearing aid technology. This works in a similar way as CROS, but increases the sound as well as simply transmitting it.

Powered Up

Most models of hearing aid technology require the user to routinely change or recharge the battery. Nevertheless, there are nowadays disposable hearing aids designed to use less power, so that the battery can last much longer before running out. Usually after approximately 10 – 12 weeks, the hearing aid is simply disposed of and replaced. This kind of hearing aids are usually not suitable for people with serious hearing loss.

Make sure to use a professional and reliable specialist to get your perfect hearing aid.
