Loop Performance Standard IEC 60118-4:2006
IEC60118-4:2006 is the international performance standard for induction loop systems.It sets out minimum performance levels that the system must meet.
The magnetic field strength at the listening height must be 400mA/m (rms) +/-3dB
Field strength is like the volume or loudness of the signal.If all systems are set to the same volume,hearing aid users do not need to adjust their hearing aid to use them.
- Make sure that all induction loop systems in your building perform to the standard IEC60118-4.
- Ask your installer to provide a test certificate to this effect.
