Hearing Augmentation. What It Is and Why You Need It
Did you know that 1 in 6 Australians suffer from hearing impairment, representing approximately 15.3% of the total population? Are you aware that by 2050 1 in 4 Australians will suffer from hearing impairment?
Hearing disorders are among the six most common conditions in industrialised countries that have the greatest impact on quality of life. Even minor hearing loss is a disadvantage in a world of rapid information exchange and not only leads to difficulties in understanding speech but also isolation and social withdrawal. With this, it is important to consider hearing augmentation in your workplace.
So what technology do you choose? Here we explore a few of the currently available systems and how they work.
Induction Loop Systems
Aninduction or Audio Frequency (AFIL) or hearing loop system transmits an audio signal directly into a hearing aid via a magnetic field. When a hearing-impaired person’s hearing aid is switched to T-mode, the T-coil picks up the signal from the magnetic field and converts it back into audible sound.
An IR system uses infrared light to transmit an in-room audio signal source from a transmitter mounted within the room to a receiver worn by the user. People with hearing aids utilise a neck loop receiver that allows the coupling of the magnetic field signal withthe Telecoil in the hearing aid, and people without hearing aids utilise headphones or headsets.
An FM system uses frequency modulated radio waves to transmit an in-room audio signalsource from a transmitter to a receiver worn by the user. Like IR Systems, peoplewith hearing aids utilisea neck loop receiver that allows coupling of the magnetic field signal with theTelecoil in the hearing aid, and people without hearing aids utilise headphonesor headsets.
The basic concept of a WiFi hearing augmentation system is utilisation of an existing or new network infrastructure to transmit an audio signal source over WiFi to a user's personal mobile device. The user downloads an app and connects to the venue’s wireless network to receive a live audio stream in real-time, and in high quality on their device. Once in the app the user can simply choose a channel from the venues stream list.
To be in compliance with section D3.7 Hearing Augmentation of the National Construction Code (NCC), a hearing augmentation system MUST be provided where an inbuilt amplification system, other than one used for emergency warning, is installed.
