Title: The Innovative Contributions of John Sheerin
Introduction
John Sheerin is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of acoustic technology, holding a total of 5 patents. His work primarily focuses on developing advanced microphone systems that enhance audio quality and performance.
Latest Patents
One of John Sheerin's latest patents is the self-calibrating multi-element dipole microphone. This innovative microphone is formed from two omni-directional acoustic sensors. It includes a sound source that is acoustically coupled to the acoustic sensors and a processor. The sound source is excited with a test signal, exposing the acoustic sensors to acoustic calibration signals. The processor compares the responses of the acoustic sensors to these calibration signals and determines one or more correction factors. Digital filter coefficients are then calculated based on these correction factors and applied to the output signals of the acoustic sensors. This process compensates for differences in the sensitivities of the acoustic sensors. The filtered signals provide acoustic sensor outputs with matching responses, which are then subtractively combined to form the dipole microphone output.
