Preview
Summary
This international standard is applicable to audio-frequency induction loop systems producing an alternating magnetic field at audio frequencies and intended to provide an input signal for hearing aids operating with an induction pick-up coil. The standard specifies requirements for the field strength in audio-frequency induction loops for hearing aid purposes, which will give adequate signal-to-noise ratio without overloading the hearing aid. The standard also specifies the minimum frequency response requirements for acceptable intelligibility.
Notes
DIN EN 60118-4 (1999-08) remains valid alongside this standard until 2009-11-01.*A transition period, as set out in DIN EN 60118-4 (2015-10), exists until 2018-01-15.
