A digital hearing aid is basically a hearing aid appliance that receives digital sound from a source and breaks it up (breaks up sound waves into discrete, tiny units) before amplification. Digital hearing aids will amplify the former and minimize the latter, for better performance in all kinds of environments. Digital hearing aids work on the principle of the superheterodyne principle, which means that they receive sound from any one source, break it up and send it out as sound through the speaker. In this way, the person wearing the aid hears not only in mono (one sound wave at a time) but also in stereo (two or more sound waves at once). Digital aids are very easy to install, require no wires, and eliminate the need for conventional amplifiers or speakers.
However, it is worth pointing out that although digital hearing aids are relatively cheap compared with their analog counterparts, they do not tend to compensate much for an inherent hearing loss. This is because a good portion of what a digital aid transmits is noise, rather than the actual sounds themselves. The wearer’s brain has to make the interpretation of the transmitted noise on its own, resulting in reduced effectiveness of the aid. In addition, it must be remembered that a single digital aid can handle all sorts of background noises and so cannot be used to isolate one person from another when multiple people are trying to listen to the same thing.
There are two main types of digital hearing aids in use today: wireless and hardwired. A wireless device works by picking up and responding to the natural frequency of the wearer’s own hearing and amplifies it accordingly. Hardwired aids work by putting in wires across the ear canal so that the transmitted sounds are much stronger and can easily penetrate the outer skin layer. The latter has the obvious advantage that it eliminates the need for wires and also the unwelcome noise created by electric signals in general.
The first step in purchasing digital hearing aids is to go for a hearing care professional’s assessment. The doctor will conduct a thorough exam in order to assess any possible problems and come up with a personalized treatment plan. The health insurance scheme may cover the cost of some devices, but you will need to pay for the evaluation and other administrative costs on your own. If you are suffering from certain kinds of loss, however, such as sensorineural loss or conductive loss, it may be well worth the expense to have both treatments done at the same time to ensure optimum effectiveness.
There are a number of companies that manufacture digital hearing aids, so it is worthwhile shopping around. Make sure to check out the experience and technical know-how of each company, and make sure you choose a supplier that can offer you the best possible price. There are many types of hearing aids, so it is worth finding a supplier that can offer the one that best suits your needs. Do not buy a high-end digital technology hearing device if it is not going to help you with your hearing loss. Choose a specialist company that can take you through the selection process confidently.
Basic hearing aids work using manual adjustments and may be affordable for many people. However, you will still have to pay for the evaluation and other administrative costs. Digital technology has revolutionized the field of hearing loss correction, making digital hearing aids much more sophisticated and affordable than ever before. The ability to adjust the volume much lower than with manual adjustments, along with the ability to easily navigate between various settings makes digital hearing aids an excellent choice for most people.
There are two basic types of digital hearing aids – monoblock and multimode. Monoblock hearing aid functions in the same way as a conventional analog hearing aid – it only amplifies the signal by a factor of half of its original level. Multimode hearing aids, on the other hand, use a different amplifier circuit design. They allow the wearer to choose between volume amplification, tone adjust, bass boost, and other features depending on the level of impairment and frequency range desired. The difference in signal strength and clarity means that each wearer will hear a different sound signature with a multimode unit, making for a much more personalized experience.
In addition to the obvious personalization benefits of having digital hearing aids, you can also enjoy a number of extra benefits. These benefits include a greater range of compatibility with all types of devices, such as iPods, MP3 players, and other wireless devices. Your options are almost unlimited thanks to modern technology. For even more flexibility, some models have a USB interface, so they can be used with portable electronic devices like laptops. As you can see, there are countless advantages to using digital technology to improve your hearing loss experience.
