Hearing aids and cochlear implants are very effective in small, quiet spaces. In public venues, they can be counter-productive because they amplify all sounds and that leads to distortion and interference with understanding language.

Induction loop amplifiers and overhead loops installed in NYC at the 9/11 Memorial & Museum allow visitors with hearing loss to enjoy the audio experience linked to the Museum’s visual displays. Since that project, other museums have also been “looped” with a variety of solutions — overhead discs, under counter, counter-top and phased arrays for theaters.
