Hearing aid is a simple device which helps people with hearing ailments to enable them to listen to sounds like normal people. Hearing impaired have difficulties in distinguishing between sounds which would be categorized as mild hearing impairment, but there are people who have lost the ability to hear who fall under the category of severe hearing impairment.

Hearing aids are designed and developed keeping in mind the different levels of impairment.

But there are so many models and makes to choose from after narrowing down the severity of the ailment.

Audicus Dia: This is a one of the behind-the-ear model digital hearing aid, which is best suited for people with severe hearing loss between 50–85 decibels. The Audicus dia is a compact amplifier with four memory programs to suit different hearing environments. The best part of digital hearing aids is that they can be programmed to provide best possible output and natural sound in different environments.

Audicus Uno: The Uno falls under the category of completely-in-the-canal hearing aid which is a very compact and virtually undetectable type of hearing aid. The hearing aid is designed to deliver natural sound quality for people who have mild to moderate hearing loss which is classified in the range of 0–65 decibels.

HCX hearing aids: This is another digital hearing aid which fits behind the ear, featuring a small but powerful amplifier. This hearing aid is also programmable to suit different environments, with three distinct levels of sound settings. Digital hearing aids are adept to distinguish between soft sounds and loud sounds, which is essentially background noise and speech to give you the best hearing output.

hiBTE, MDHearingAid, Ovation, Phonak, Pro Ears, Siemens, and Simplicity HiFi are just some of the other popular models which are available in the market for the best price amongst many others.
