Digital Hearing Aids vs. Analog Hearing Aids

Analog hearing aids

When we talk of hearing devices we mostly think of analog hearing aids. They have been around the corner since decades and have helped millions of hearing impaired people. These are simple devices which amplify the sound waves by making them louder enough for the people to hear.

The sound can be controlled by the user by using a volume switch. Though analog hearing devices are great for raising the volume but in this process they also amplify all undesirable sounds which a person may not want to hear at all.

Except this disadvantage, these hearing aids are very functional and effective and their batteries are also packed with more power so they last more as compared to digital hearing aids. These hearing devices are much cheaper than their digital counterparts.

Digital hearing aids

Today, digital hearing aids are being preferred by most people due to the immense benefits they offer to their users. These aids came into being in mid 80’s.

These hearing aids receive the sound and then turn these sound waves into digits. An onboard microcomputer chip in their circuit processed this data and the resultant sound is then relayed to the user.
Being smart devices, these digital hearing aids regularly transform all type of sounds into digits which are processed in computer chips using some mathematical formulas which can be customized as per the user needs.

This processing enables these digital hearing aid devices to completely filter out any annoying background noises typically heard in analog hearing aids. Many high end models of these digital hearing aids can be easily programmed as per the requirements of its user though computer or internet. This eliminates any need for the repeat visits to the doctor for having these devices reprogrammed again and again.

However, these digital hearing devices are very costly and therefore become unaffordable for many people. These hearing aids also consume lot of battery power and therefore require frequent charging.

The technology for placing such tiny processing chips in the hearing aids came from music recording industry and military. A great thing about digital hearing devices is that they can clearly differentiate between the human voice and background noise as a result of which they can successfully filter out any noise.

It is essential for you to visit an audiologist if you are interested in acquiring a hearing aid for yourself. They can provide you proper guidance on way to acquire most suitable hearing aid as per your hearing loss. It is not necessary for you to buy your hearing devices from them as you can get much better deals on the internet.
