Receiver-in-canal (RIC) hearing aids sit behind the ear and deliver sound directly into the ear. This is because the receiver is located outside of the hearing aid itself and instead inside ear canal. The hearing aid and receiver are connected by a discreet ‘receiver wire’ which houses an electrical cable.
RIC hearing aids house either a size 10 (Yellow), size 312 (Brown) or size 13 (Orange) battery depending on the style and size selected. The typical lifespan of a size 10 battery is between 3-5 days, size 312 battery between 5-7 days and size 13 battery between 10-14 days but this can vary depending upon the number of hours per day the hearing aid is worn, the severity of hearing loss and the technology level of hearing aid.
Their design is based on the traditional BTE hearing aid, however the revolution sits in the separation of the microphone, amplifier and processor into a small casing that sits behind the ear, and then putting the receiver/speaker into a small dome that sits directly in the ear which is connected to the casing via a thin wire. This results in them being smaller, suffering less from feedback and producing a more natural sound.
