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.

First claim

The invention claimed is:

1. A hearing-ability measurement device that measures a hearing-ability of a subject, said hearing-ability measurement device comprising:
a processor;
a test sound generation unit configured to generate a test sound, the test sound including a probe and a masker;
a test sound output unit configured to output the test sound generated by said test sound generation unit;
a perception examination unit configured to examine, using the processor, whether…
