Why Are Hearing Loops Needed?

Don’t hearing aids enable hearing?

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.
