OTOACOUSTIC EMISSION MEASURING METHOD AND APPARATUS USING FREQUENCY SWEEPING AND LEVEL SWEEPING

摘要

PURPOSE: An otoacoustic emission measuring method and apparatus are provided to reduce the time for measurement of otoacoustic emission by implementing level sweeping only on a frequency band in which otoacoustic emission drastically changes. ;CONSTITUTION: An otoacoustic emission measuring method comprises a step(810) of implementing frequency sweeping on N(N is a natural number more than 2) signals of different levels to generate otoacoustic emission graphs according to frequency and a step(820) of correcting the graphs in a frequency band including a frequency band in which some of the graphs are overlapped.;COPYRIGHT KIPO 2011
