Abstract

A BTE hearing aid (BTE: Behind-The-Ear) is usually worn by attaching the earhook to the pinna of the ear. A typical earhook is assembled by screwing it into the BTE hearing aid. This way, the earhoock is locked tightly to the hearing instrument and individual adjustments can be done on the earhook for each user. These earhooks are often only available in fixed sizes and therefore not customizable, which can result in discomfort for the user. Currently, no adjustable earhook design exists. The user can only replace the earhook by a so called lifetube which is more flexible and suits better to individual ears. The drawback of using lifetubes is the leakage of sound caused by adopting an open fit concept. This has a negative influence on the experienced sound quality.

Adjustable Earhook on SOC via Ball Joint

                            respect to the rest of the BTE hearing aid, as depicted in Figure 3. The inserted rubber piece which is located in the earhook, prevents leakage of sound and sweat intrusion. It also damps vibrations between the earhook and the SOC and therefore stabilizing the whole BTE instrument.

             n can advantageously be used to create an adjustable earhook preventing leakage of sound and stabilizing the BTE hearing aid.
