Bone conduction masking dilemma
WebWithout masking during bone conduction, we assume responses could be from both ears, or the better-hearing ear (which we cannot identify until we mask). Additionally, because … 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.

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 ...
WebA masking dilemma occurs when: A. it is impossible to mask. B. the patient displays a bilateral conductive loss. C. masking cannot be completed due to overmasking. D. all of the above. ( Correct Answer) Under masking is defined as: A. occurring more often during air conduction testing. Central masking can effect a threshold by : 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 …
WebSince the unmasked bone-conduction thresholds represent the better cochlea if there is one, the left ear’s bone conduction thresholds will not show a conductive component even if it were to be tested. In contrast, Figure 3-3 shows a case where bone-conduction masking is needed. There may be air-bone gaps for both the right and left ears ... WebHere's a video describing and showing an air conduction masking dilemma. We usually only talk about masking dilemmas that occur for BC testing, but they can ...
