Today’s digital hearing aids enhance hearing in conversational settings.
Yet for many people with hearing loss the sound becomes unclear when auditorium
or TV loudspeakers are at a distance, when the context is noisy, or when room acoustics reverberate sound.
A hearing loop magnetically transfers the microphone or TV sound signal to hearing aids and cochlear implants
that have a tiny, inexpensive “telecoil” receiver. This transforms the instruments into in-the-ear loudspeakers
that deliver sound customized for one’s own hearing loss.
