Notes and requirements of Standard 60118-4
The standard states that the signal level in the loop area should not vary by more than ± 3dB.
Once confirmed, the signal level from the normal building program should peak at 0 dB as
referenced at 400mA/m. This confirms that there is adequate loop current to produce both
maximum and average signal levels (average is de-12dB or 100ma/m) for hearing instruments
equipped with the T position.
