How hearing aids work?

All hearing aids use the same basic parts to bring sounds from the environment into the ear and make them louder. Most hearing aids are digital and all work with a traditional hearing aid battery or a rechargeable battery. In addition, channel aids have less space available for batteries and additional devices, such as a telephone coil. Some private insurance policies cover part or all of the cost of hearing aids; check your policy to be sure.

Digital circuitry gives the audiologist more flexibility to adjust the aid to the needs of the user and to certain listening environments. The reason that today's hearing aids are much more than just amplifiers is the way they can selectively amplify sound. As the code also includes information about the pitch or volume of a sound, the aid can be specially programmed to amplify some frequencies more than others. Many modern hearing aids have directional microphones, which means that they determine in the moment which sounds belong to their conversation partner and focus on those sounds, rather than all other background noises.

Small, open aids fit completely behind the ear, with only a narrow tube inserted into the ear canal, allowing the canal to remain open. In addition, researchers are investigating the use of computer-aided technology to design and manufacture better hearing aids. In addition, some people may prefer the open hearing aid because their perception of their voice does not sound “stuffy”. For eligible children and young adults age 21 and under, Medicaid will pay for diagnosis and treatment of hearing loss, including hearing aids, under the Early and Periodic Screening, Diagnosis and Treatment (EPSDT) service.

Some people are born without an external ear or ear canal, which means they can't wear a typical hearing aid. Hearing aid technology has improved dramatically over the years, giving you a range of comfortable and discreet devices that fit your lifestyle. Hearing aids with multiple programs can automatically switch from one program to another or can be changed manually by the individual. An audiologist can program help with a computer, and you can change the program for different listening environments, from a small, quiet room to a crowded restaurant or large, open areas such as a theater or stadium.

Hearing loss can have a big impact on your life, from your work to your relationships to your emotional well-being. Depending on the brand and model of hearing technology, you can use the app to control volume and settings, set program preferences for favorite locations, and even stream audio from your smartphone directly to your hearing aids.
