Bone conduction masking dilemma
WebEffective Masking. The amount of noise that definitely makes a specific signal such as a pure tone inaudible in the non-test ear. Occlusion Effect. The occlusion effect is an enhancement or improvement in bone-conduction hearing for lower-frequency sounds. The occlusion effect occurs in patients with middle ear disorders and also in normal ... WebDuring bone conduction testing, a masking dilemma may occur when the air-bone gap of the nontest ear is greater than or equal to the interaural attenuation minus 15 dB (ABG …

WebMonaural masking levels for the nontest ear (assuming 10 dB of interaural attenuation) recommended clinically are as follows: (1) 500 Hz: 72 and 82 dB SPL at 20 and 30 dB … http://www.audsim.com/mbook/c6.html
WebUsing the minimum IA value of 40 dB (headphones) as our criterion, masking for AC is needed whenever the test ear's conduction threshold (ACt) and the nontest ear's bone-conduction threshold (BCn) differ by 40 dB or more. Some audiologists call the spread between ACt and BCn an air-opposite-bone-gap (AOBG) or an air-contralateral-bone … WebMasking Dilemmas. When it becomes impossible to mask effectively for air or bone conduction testing. Plateau Method (The Hood Technique) The plateau is the point at which the threshold in the test ear does not change with increases in the masking level. Pg 122-123. Sets with similar terms.
