It took a lot of time to test the hearing loss, and old
people were difficulty in having a concentration for a long time.
The purpose of this study is to setup a fast self-test of finding the
hearing level. We suggested two ideas to reduce time and steps.
First, we expected the first sound using an average and an
extended scope of levels. Second, the test of unnecessary
frequency was skipped. We assume that the hearing level of the
normal was similar to other frequencies or existed in regular
range. A pure tone was generated from device based on the
expectation of hearing level. If the hearing level of subject was
under 30dB, test in some frequencies could be skipped. It is able
to save the whole time as reducing steps in each frequency.
