Hearing support for the hearing impaired
avidec relies on several technologies in the field of hearing support for the hearing impaired. We plan your hearing loop and help with the loop laying.
Inductive hearing systems
Inductive hearing systems
Inductive hearing systems transmit the speech signal via magnetic field in speech frequency. A receiving coil (known as a telephone or induction coil) is built into the hearing aid to pick up the magnetic signal. This type of transmission also works when telephoning with suitable telephones.
The international standard IEC 118-4, valid in Switzerland as SN EN 60118-4:2015, exists for inductive hearing systems. For inductive hearing systems, the induction loop or the induction loop system must be installed by the customer (loop laying).
A prerequisite for a hearing system or hearing loop that functions in accordance with standards is professional planning, based on planning measurements at the construction stage or before a renovation.
Infrared hearing systems
Infrared hearing systems
Infrared systems transmit the speech signal via invisible light in the infrared range. People wearing hearing aids need special receivers so that they can hear without headphones. The transmission from the receiving device to the hearing aid takes place via induction (induction neck loop, induction plate) or via a cable to the audio shoe.
FM systems (radio)
FM systems (radio)
FM hearing systems transmit the speech signal via radio. Hearing aid users need a radio receiver built onto or into the hearing aid or a special receiver in order to hear without headphones. The transmission from the receiving device to the hearing aid takes place via induction (induction neck loop, induction plate) or via a cable to the audio shoe.
