Masking of pure tones and speech

WebThis chapter summarizes what is known about the discrimination of sounds that differ in intensity. The topics are: (1) differential intensity limens for pure tones; (2) intensity discrimination tasks in which random noise is used as a masker; and (3) discrimination of intensity changes in complex signals. Web1. find starting masking level by finding AC threshold of TE minus 10. 2. re-establish 3. present-see how much threshold shifted due to masker. 4. increase masking by the same amt you increased the TE threshold and re-establish 5. present again, if threshold does not change, that's your threshold
