Introduction

William M Humphreys, Jr. is a notable inventor based in Newport News, VA (US). He holds a total of 4 patents that showcase his contributions to the field of acoustic technology. His work primarily focuses on advanced microphone systems and methods for mapping acoustic sources.

Latest Patents

One of his latest patents is titled "Acoustic beam forming array using feedback-controlled microphones for tuning and self-matching of frequency response." This invention involves a feedback-controlled microphone that includes a microphone body and a membrane connected to it. The membrane is designed to be initially deflected by acoustic pressure, characterized by a specific frequency response. The microphone also features a sensor that detects this frequency response and generates an output voltage. A compensator is in electric communication with the sensor to establish a regulated voltage in response to the output voltage. Additionally, an actuator is configured to secondarily deflect the membrane to adjust the frequency response. This patent also discloses an acoustic beam forming microphone array comprising multiple feedback-controlled microphones.

Another significant patent by Humphreys is "Deconvolution methods and systems for the mapping of acoustic sources from phased microphone arrays." This invention focuses on mapping coherent and incoherent acoustic sources using a phased microphone array. It involves forming a linear configuration of equations and unknowns that account for the reciprocal influence of cross-beamforming characteristics at various grid locations. The derived equation can be iteratively determined, leading to an optimized noise source distribution over an identified aeroacoustic source region.
