I wanted to get some input on everyone's views. When determining the need to mask for speech, I have been instructed by multiple preceptors to compare the presentation level in the test ear to the bone conduction threshold in the non-test ear at 2kHz. Obviously if the difference exceeds the interaural attenuation level of the transducer you are using, contralateral masking would be necessary. However, I have read in text that because speech noise is a broadband stimulus, you should account for multiple frequencies in the nontest ear(with the exception of 250Hz). Thus you would compare the PL with the best BC threshold at any frequency in the NTE.. Any thoughts or experiences?
