earphones or 55 dB or when using insert earphones Rule 2: Masking is needed at any frequency where the not-masked b-c threshold is more acute than the air-conduction threshold of either ear by 10 dB or more. The worse ear (by air conduction) would then be the test ear and the better ear would be the non-test ear to be masked.
