WebOccurs when enough masking is too much masking; can't effectively mask bc of cross-over Most likely occurs when trying to determine if patient has bilateral conductive hearing loss, mixed HL in one of both ears (sig A-B gap and occlusion effect require more loud sound), conductive loss in one ear and no hearing in other WebEffective Masking (EM) Definition: The minimum about of noise required to make a given signal inaudible. For example, 35 dB EM at 1000 Hz is just enough noise to make a 35 dB HL 1000 Hz tone inaudible. 35 dB EM at 1000 Hz, a 1000 Hz tone will not be audible until it reaches. a level of 40 dB HL or higher. inline hockey chassis
