An audiogram reflecting cross-hearing before masking application Shadow curves usually seen when thresholds of the ear with greater hearing loss (e.g. severe or profound) are a reflection (mimic) of thresholds of the ear with normal or near normal hearing levels.
Pure tone audiometry - SlideShare

MASKING Masking is done by: 1.White noise-consists of sound of all frequencies from high to low. 2.Narrow band noise-more effective for masking, consists of a narrow band of noise 100-200 Hz above/below that frequency. 3.Complex noise-low frequency fundamental+multiples of frequencies up to 4000 Hz. Least efficient for masking. 20.

MASKING IN PURE TONE AUDIOMETRY Purpose of the test The technique of masking is used in order to isolate the test ear and ensure that results obtained are the true thresholds of the test ear. In pure tone audiometry for both air conduction and bone conduction it is possible that responses obtained are those of the non-test ear.

Audiometry. 1. Audiology part i Dr Humra Shamim. 2. Evolution of audiology • Prior to World War II, hearing-care services were provided by physicians and commercial hearing aid dealers. • Because the use of hearing protection was not common until the latter part of the war, many service personnel suffered the effects of high-level noise ...

Figure 4: Masking noise should be louder. Purple indicates that masking is needed but non-feasible (Figure 5). Figure 5: Masking non-feasible. Caveats (1) Be aware that patients need proper instructions before audiometry with masking is undertaken. (2) The switching-on-and-off of the masking noise may be uncomfortable to some patients and cause ...
