Publication number: 20230172493Abstract: An acoustic otoscope generates volume change excitations of either a trapezoidal or sinusoidal waveforms which are coupled into a sealed ear canal using a speculum tip. The change in volume results in a pressure change, for which a pressure measurement is taken during the volume change excitation interval. In one example, a trapezoidal time-domain volume change is presented, and a pressure measurement waveform is stored, the pressure measurement waveform thereafter examined to find a change of slope point in time, after which the pressure measurement waveform is scaled to be equal to the volume change waveform at that same point in time, a difference between scaled pressure measurement and volume excitation is formed, and examined for peak value prior to the earlier determined change in slope point in time.Type: ApplicationFiled: August 3, 2022Publication date: June 8, 2023Applicant: OtoNexus Medical Technologies, Inc.Inventors: Mark A.
