Members: 800-498-2071 An official website of the United States government. Ear and Hearing, 18(6), 440455. Even those with a profound hearing impairment, the most severe type, can hear some sound. The intensity level is then progressively lowered, and the responses tracked, until an intensity is reached at which the response is no longer observable. The frequency presentation order is not likely to significantly influence test results; however, using a standard order can ensure consistency and minimize the risk of omissions (American National Standards Institute [ANSI], 2018b). Reducing the test set size by including only familiar words may result in inaccurate threshold measurements.
