masking level difference

masking level difference

a technique of comparing threshold responses with masking noise presented in phase and out of phase with the test signal; release from masking is normal and indicates an intact brainstem auditory pathway.

mask·ing lev·el dif·fer·ence

(mask'ing lev'ĕl dif'ĕr-ĕns)
A technique of comparing threshold responses with masking noise presented in phase and out of phase with the test signal; release from masking is normal and indicates an intact brainstem auditory pathway.
