A method to reduce steps and time of hearing test on individual device

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.
