This hearing aid is intended for hearing-impaired people to compensate hearing loss and assist daily listening and communication. It adopts digital chip solution with ultra-low power consumption, integrating filtering, noise reduction and WDRC algorithms. It provides three volume levels with double-click cyclic switching, and is built with dedicated noise mode and volume memory function. The device automatically powers on 3 seconds after being taken out of the charging case and automatically powers off when placed back, supporting left and right ear universal wearing. Double-click operation comes with prompt sound. Both the hearing aid and charging case are equipped with charging indicators, and the charging case has power display function. Designed as a mini-sized model, it supports howling suppression, low power consumption, long standby and comfortable wearing.
A battery-powered acoustic device intended to compensate for impaired hearing by transmitting amplified sound waves to the eardrum through air. It typically consists of a microphone, an amplifier, and a speaker (receiver) contained in a case worn behind-the-ear (BTE). The microphone receives sound waves and converts them into electrical signals which are increased by the amplifier and sent as sound waves, by the speaker, to the eardrum through an earmould that fits inside the outer ear or a tube in the ear canal. The device is used for mild to profound hearing loss; most types are programmable to enable computerized adjustments for a patient's hearing loss and related factors.
