Contralateral masking

WebIt is recommended that the contralateral (nonstimulated) ear be masked by white noise at 60 dB SPL to eliminate “crossover” responses, i.e., bone-conducted responses originating in this ear. Although not necessary in every situation, it is recommended that contralateral masking be included in the routine test protocol to avoid its inadvertent Ipsilateral ("same side") masking is not the only condition where masking takes place. Another situation where masking occurs is called contralateral ("other side") simultaneous masking.
