发明名称 In the ear auxiliary microphone for behind the ear hearing prosthetic
摘要 An In The Ear (ITE) microphone which converts audio sounds into electrical signals which are then processed by a speech processor to generate electrical pulses to stimulate nerves in the cochlea, improves the acoustic response of a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system during telephone use. An acoustic seal provided by holding a telephone earpiece against the ear provides improved coupling of low frequency (up to about 1 KHz) sound waves, sufficient to overcome losses due to the near field acoustic characteristics common to telephones. In an exemplary embodiment, the ITE microphone is connected to a removable ear hook of the BTE ICS system by a short bendable stalk.
