You don't have to plug into the loop, you just have to be seated within the magnetic field it produces. The person's own hearing aid does the work. Therefore any number of people can benefit at one time. The audio loop would give hearing aid wearers access to live theatre, films, concerts, lectures, meetings and church services, all of which they rarely attend as the hearing aid picks up so much background noise that the wearer cannot understand the speaker. For libraries, churches, theatres or public auditoria where the audio loop has been installed, laminated identification signs are available.
Small signs are available for rows of theatre seats or church pews which are in the looped area.
Postcard sized signs are available for use at entrances to theatres, libraries, churches and other public venues.
