## Indications for use
The hearing aid is a disposable, extended-wear air conduction hearing aid, designed to be used and worn by hearing-impaired persons. Hearing assistance is achieved through amplification of sound pressure waves, which are transmitted to the external ear canal via air conduction. The hearing aid is initially placed in the ear canal by an appropriately trained ENT physician, Audiologist or Hearing Aid Dispenser and can remain in the ear canal for up to 4 months or until the battery is depleted. It is then replaced by a new device by the previously mentioned parties, or by an adult patient 22 years and older who have been wearing Lyric for a minimum period of 3 months under the direction and training of the ENT physician, Audiologist or Hearing Aid Dispenser. Upon device removal the hearing aid is discarded.
