RIC Rechargeable Mini Invisible Hearing Aids for Severe Hearing Loss
RIC (Receiver In The Canal) is also known as CRT (Canal Receiver Technology). CRT technology separates the receiver from the main body of the hearing aid and places it directly into the ear canal, where it is connected by an external tube with a special metal wire.
The advantages of CIC hearing aids
●Naturally increased gain and sound output, more powerful, can meet the severe hearing loss patients;
●Smooth output frequency response curve, greater overall loudness, easier to achieve compensation targets, more beautiful sound quality.
●Wider frequency compensation range (100~7000Hz), better use of frequency response range, more high frequency compensation.
●The microphone and receiver are farther apart, effectively eliminating acoustic feedback.
●Receiver closer to the tympanic membrane, the sound is more natural and realistic.
●Reduced ear plugging effect (for ear molds, larger ventilation holes can be applied because the microphone and receiver are positioned farther apart, and for ear plugs, open or semi-open ear plugs are available).
●A more compact, beautiful and concealed appearance.
