Why are hearing loops needed? Don’t hearing aids enable hearing?
Today’s hearing aids enhance hearing in conversational settings. Yet for those with hearing loss the sound becomes unclear when loudspeakers are distant, when the context is noisy, or in rooms that reverberate sound. A hearing loop magnetically transfers microphone or TV sound signal to hearing aids and cochlear implants that have an inexpensive “telecoil” receiver. This transforms the instruments into in-the-ear speakers that deliver sound customized for one’s own hearing loss.
