Abstract
Provided is a hearing-ability measurement device and a method thereof for measuring a masking curve more correctly and in a shorter time. A test sound generation unit generates a test sound including a probe and a masker, and outputs the test sound from a test sound output unit. A perception examination unit examines whether or not the subject perceives the probe. An adjustment unit adjusts acoustic properties of the test sound, based on a result of the examination. Here, kinds of adjusted acoustic properties are different between the situation of prove perception success and the situation of prove perception failure. As a result, the masking curve is directly tracked and the measurement is performed more correctly and in a shorter time.
