Title: Sylvain Angrignon: Innovator in Acoustic Technology
Introduction
Sylvain Angrignon is a notable inventor based in Kanata, Canada. He has made significant contributions to the field of acoustic technology, holding a total of 3 patents. His work focuses on innovative methods for signal processing and environmental detection in audio systems.
Latest Patents
One of his latest patents is for a back cavity microphone implementation. This system and method perform signal processing using a loudspeaker output. The design includes an enclosure that defines a back cavity of the loudspeaker, along with components that capture the acoustic output at this back cavity. A processor is integrated to process this representation for effective signal processing.
Another significant patent involves using an auxiliary device sensor to facilitate the disambiguation of detected acoustic environment changes. This technology allows audio input to be received at one or more microphones of a mobile device. It can detect changes in the acoustic environment, such as variations in the direction of audio input or degradation in acoustic echo cancellation quality. The system can determine if these changes coincide with non-acoustic physical events, such as device motion or changes in proximity to objects. Based on this determination, the signal processor can be recalibrated to enhance performance.
