Abstract
A method and apparatus for administering a hearing test that emits a test sound with changing volume with respect to elapsed time. The volume changes according to a pre-determined relationship between the volume and elapsed time. The hearing test utilizes the elapsed time until a subject signals the test sound is audible, and the pre-determined relationship, to determine the subject sound pressure level threshold for the test sound.
