Title: Nima Yousefian: Innovator in Acoustic Source Detection
Introduction
Nima Yousefian is a notable inventor based in Tempe, AZ (US). He has made significant contributions to the field of acoustic source detection. His innovative work focuses on identifying noise sources through advanced signal processing techniques.
Latest Patents
Nima holds 1 patent for his invention titled "Temporal and spatial detection of acoustic sources." This patent describes a method for identifying noise sources, such as televisions or talkers, by analyzing phase information from microphone signals. The process involves computing a phase delay variance from pairs of microphone signals. Over time, a profile of an interference source can be learned and updated when the phase delay variance is below a certain threshold. This stored profile aids in identifying interference sources by correlating microphone signals with the profile. When an interference source is detected, control parameters can be generated to adjust a beamformer, thereby reducing the interference in the output audio signal. This technology has applications in speech processing, particularly in smart home devices.
