Why do hearing aids go behind the ear?

Behind the Ear A tube connects the hearing aid to a custom earpiece called an ear mold that fits into the ear canal. This type is suitable for people of all ages and people with almost any type of hearing loss. Behind-the-ear hearing aids, as the name implies, are worn behind the ear. This type of hearing aid, which is in a case, connects to a plastic mold inside the outer ear.

These hearing aids are usually used for mild to severe hearing loss. Poorly fitted BTE hearing aids can cause feedback, an annoying whistle, in the ear. However, all hearing aids can receive feedback. Behind-the-ear headphones also provide high-quality sound to the wearer.

You may be wondering how this provides such high quality sound when you are on the outside of your ear and this is a big question. While the microphone is placed on the top of the ear, the receiver is connected to it via a thin, transparent tube. This tube is placed inside the ear, which helps direct sounds around it. This combination of having a part in the outer ear and having a part inside the ear comes together to provide high quality sound to anyone who wears them.

In today's hearing aid market, there are plenty of options to choose from. Behind-the-ear (BTE) hearing aids are one of those options. BTE hearing aids conform to the ear by snapping and snugly fitting in the back, behind the outer ear. The hearing aid is connected to the ear canal by a thin tube that is placed in an earphone inside the ear.

The sound travels down the tube into the ear canal. You can get BTE and mini BTE depending on your budget and preferences, but what are the advantages of these devices? The conclusion of the evaluation is not a medical diagnosis and further tests may be required to diagnose hearing loss. Low-profile hearing aids are similar to ITC styles and range from half-shell designs that fill half of the outer ear bowl to full-shell designs that fill almost the entire outer ear. The first thing that is important to note is that behind-the-ear hearing aids are comfortable to wear.

When it comes to hearing aids, there are multiple functions and styles available to accommodate different hearing loss needs. Researchers are looking for ways to apply new signal processing strategies to hearing aid design. However, BTE hearing aids are largely immune to this problem, because the microphone and speaker are far apart. In general, the ITE aids are not used by young children because the shells need to be replaced frequently as the ear grows.

Scientists are using the structure of the fly's ear as a model to design miniature directional microphones for hearing aids. The open fit (also called Corda MiniFit) is a thin tube that mounts to behind-the-ear headphones with a dome or micromold as an earpiece. Digital circuitry gives the audiologist more flexibility to adjust the aid to the needs of the user and to certain listening environments. Stream phone calls, TV and music directly to your hearing aids or connect wirelessly to other devices.

The hearing aid receives sound through a microphone, which converts sound waves into electrical signals and sends them to an amplifier. There are a number of problems that can be common with hearing aids that your audiologist will likely discuss with you.
