(Main)Hearing aids - Part 4: Magnetic field strength in audio-frequency induction loops for hearing aid purposes
General Information
- Abstract
Applies to audio-frequency induction loop systems producing an alternating magnetic field and intended to provide an input signal for hearing aids operating with an induction pick-up coil. Specifies a standard value of magnetic field strength in audio-frequency induction loops for hearing aid purposes, such as will give an adequate signal-to-noise ratio without overloading the hearing aid.
