U.S., April 23 -- ClinicalTrials.gov registry received information related to the study (NCT07543770) titled 'Wind Noise Sound Quality Preference and Claims Study' on April 14.
Brief Summary: Claims evidence is required for a new Wind Noise Canceller (WNC) algorithm.
Wind noise is not sound in the classic sense, as it does not correspond to pressure waves moving through the air. However, because the microphone membranes are deflected by the wind noise, the microphones translates them into a sound signal. Since the pressure fluctuations are small in size, this wind noise signal is uncorrelated between the two HI microphones (correlation decreases with increasing microphone distance), creating bothersome sounds at low and very low frequenci...
