Hearing loss is generally categorized as conductive and “sensorineural”. Conductive hearing loss refers to abnormal transmission of sound to the outer or middle ear. This can be easily fixed by hearing aids that use analog technology through amplification of sound. Sensorineural hearing loss is caused by cochlear or auditory nerve malfunction. Since this is more of a sound processing problem, this requires some digital technology, and this is where digital hearing aids can help.

Hearing aids that use analog technology amplifies sound by means of magnification of sound waves. The products in the market generally have them as conventional or programmable models. Conventional models feature adjustable volume control in its circuits, while programmable models allow for more flexibility. While they both have adjustable controls, the latter has more fine-tuning capabilities in terms of sound amplification.

Digital hearing aids work by digitizing sound to produce a clean and customized sound output. They are custom-fit based on the degree of your hearing loss. Millions of algorithms perform calculations faster than you can blink in order to digitally process sound, while reducing or eliminating feedback, noise and distortion. From the collection of sound, it undergoes transformation to digital format using digital processes and translates them to recognizable analog sound. Maximum flexibility and precise fine-tuning are what makes them better instruments.

Hearing aids vary in size and shape. But they generally come down to four basic classifications. Behind the ear or BTE models have a plastic casing that houses the electronic parts used for amplification of sound. As the name says, it is worn behind the ear and has a tube that connects to an ear mold for fitting in the ear canal. They are easy to use and commonly recommended for children.

ITE’s are instruments fitted just inside the outer ear. They are used in a wider range of hearing loss, usually on patients with mild to severe problems. ITC’s are fitted further into the external ear since they are smaller, and therefore almost appear concealed. They cater to patients with mild to severe hearing loss.

Completely in the canal or CIC models are considered the smallest in size and are virtually invisible to other people since it literally fits further inside your ear canal. But it does require having an ear canal opening large enough to fit this device. They are best for mild to moderate hearing loss.

It’s easy to be confused with so much information on hearing aids out there. So how do we get a custom-fit hearing instrument? The answer will always vary since different individuals have different degrees of hearing loss. A patient’s lifestyle and communication will also be factors.

One cannot base his decision by comparing the experience and review of others regarding their hearing aids. A certain model may be good for them, but that does not necessarily mean that it is good for you too. Only by taking hearing tests and proper evaluation can you truly specify what your needs are in order to choose the right device.

Remember that your needs will always be different from others, and on choosing hearing aids, it’s no different. A doctor, audiologist or hearing instrument specialist can conduct accurate tests that will pinpoint the right instrument for you, be it analog or digital hearing aids.
