This study examined some psychometric properties of the Test of Basic Auditory Capabilities (TBAC). Two experiments are described that evaluate the psychometric functions and the test‐retest reliability of the tests comprising the TBAC. The psychometric functions were established for young listeners with normal hearing and the test‐retest reliability was evaluated both with young listeners with normal hearing and elderly listeners with hearing impairment. Results indicate that maximum scores on the TBAC are reached at presentation levels of at least 65–75 dB SPL. In addition, the reliability analyses indicate that the TBAC is a reliable measure for both young listeners with normal hearing and elderly listeners with hearing impairment when at least one practice test is given.
