Hearing Loops provide an important service for hearing aid users and others with challenging levels of hearing loss in many environments and applications, but they’re completely pointless if no none knows the facility is available to them. It’s imperative that the necessary Hearing loop signs are displayed, as the systems are, in effect, invisible and inaudible to potential users – who simply wouldn’t know to switch their hearing aid to the correct setting, or ask for a receiver, without being informed to do so. The internationally recognised Hearing Loop sign consists of an ear graphic with a T and brief instructions for those unfamiliar with the technology.
