Title: Fabien Bonnet: Innovator in In-Ear Noise Dosimetry

Introduction

Fabien Bonnet is a notable inventor based in Montreal, Canada. He has made significant contributions to the field of acoustics, particularly in the area of in-ear noise dosimetry. With a total of 2 patents, Bonnet's work focuses on enhancing the understanding and measurement of sound exposure in various environments.

Latest Patents

Bonnet's latest patents include a system and method to perform in-ear noise dosimetry and personal attenuation rating under an electro-acoustic earplug while excluding wearer-induced disturbances. This innovative system is designed to measure noise reduction and evaluate the contributions of various sound sources to noise exposure dose using electro-acoustic earplugs. The system can be implemented as an advanced hearing protection device (HPD) in the form of an electro-acoustical earplug, which comprises an OEM and an IEM. It is configured to calculate an estimated IEM signal based on the calculation of estimates of residual ambient noise, payback sounds, or wearer-induced disturbances present in the ear canal.

Another significant patent by Bonnet is a method and system for measuring in-ear effective sound exposure under an earplug or without an earplug. This invention includes personalized calibration methods and devices that identify acoustical corrections to be applied for in-ear dosimetry. These acoustical corrections allow for the conversion of measured acoustic pressure within the ear canal of a user to an equivalent acoustic pressure at the ear drum and/or in free-field. The methods and devices also enable the distinction between noises originating from the user and those from the environment in the ear occluded by an earplug, using two microphones to simultaneously measure acoustic pressure.
