An inconspicuous electronic gadget worn behind or in the ear is a hearing aid. It enhances some sounds so that a person with hearing loss can communicate, listen, and take a greater interest in everyday activities. Hearing aid users can hear more clearly in both quiet and noisy settings. A hearing aids is worn by about one in five people who could benefit from one. The hearing aid’s microphone captures sound, converts it into electrical impulses, and sends those signals to an amplifier.
Many types of hearing aids
BTE (behind-the-ear) (BTE)
A hard plastic case worn behind the ear and a hard plastic earmold that works within the outer ear made up of hearing aids. The space behind the ear is where the electronic components are held in good operating order. Sound from the hearing aid enters the ear through the earmold. People with mild to severe hearing loss of all ages utilise BTE devices.
A brand-new kind of BTE device is an open-fit hearing aid. Small, open-fit devices that fit behind the ear and only need a little tube to allow the ear canal to remain open. Those who experience earwax buildup may want to consider open-fit hearing aids since they are less likely to sustain damage from earwax buildup.
Hearing aids fit into the outer ear. These help for mild to severe hearing loss. It is driven by the durable plastic housing for the electronic parts. One feature that some ITE aids might have is a telecoil. A hearing aid’s microphone and tiny magnetic coil, known as a telecoil, allow users to receive sound.Talk over the phone is easier to hear. In public places that have induction loop systems, which are specialised sound systems, a telecoil also helps with hearing.
They can fit into the ear canal and come in two different shapes. The ear canal’s measurements are provided by the in-the-canal (ITC) hearing aid. A completely-in-canal (CIC) hearing aid is concealed inside the ear canal. Both types are for hearing loss that ranges from mild to moderate.
Wholly in canal (CIC)
Because to their small size, canal aids may be rough for a person to adjust and remove. Moreover, the space available for batteries and other accessories like telecoils is declining in canal aids. Newborns or people with severe to profound hearing loss are often not advised due to their tiny size, which limits their power and volume.
