This presentation is to illustrate by typical examples the clinical evaluation of masking, recruitment, and adaptation.
Our experience with white-noise, narrow-band, and pure-tone masking indicates that of these, narrow-band masking is the most efficient. Narrow-band noise produces about 10 db. more masking effect than white noise at equal over-all intensity levels.Presentation of the masking signal may be by conventional phone, insert receiver, or bone conduction receiver. The insert receiver has the advantage of permitting greater intensities without producing cross
