Extended wear hearing aids

Extended wearHearing aids are hearing devices that are non-surgically placed in the ear canal by a hearing professional. The extended wear hearing aid represents the first "invisible" hearing device. The concept was invented byAdnan Shennib.These devices are worn for 13 months at a time without removal. They are made of soft material designed to contour to each user and can be used by people with mild to moderately severe hearing loss. They work by directing sound into the ear canal from the outer ear.

Their close proximity to the ear drum results in improved sound directionality and localization, reduced feedback, and improved high frequency gain.While traditional BTE or ITC hearing aids require daily insertion and removal, extended wearHearing aids are worn continuously and then replaced with a new device. Users can change volume and settings without the aid of a hearing professional. The devices are very useful for active individuals because their design protects against moisture and earwax and can be worn while exercising, showering, etc. Because the device's placement within the ear canal makes them invisible to observers, extended wear hearing aids are popular with those who are self-conscious about the aesthetics of BTE or ITC hearing aid models. As with other hearing devices, compatibility is based on an individual's hearing loss, ear size and shape, medical conditions, and lifestyle. The disadvantages include regular removal and reinsertion of the device when the battery dies, inability to go underwater, earplugs when showering, and for some discomfort with the fit since it is inserted deeply in the ear canal in the only part of the body where skin rests directly on top of bone.
