Hearing Augmentation
Hearing augmentation is the process of collecting audio from amplification systems such as public address or audio-visual systems for transmission to receivers built into the personal hearing devices worn by the hard of hearing.
Some hearing augmentation solutions require the use of external neck-worn receivers to provide access. NCC/BCA stipulate the number of receivers you require based on the capacity of the space.
