The most commonly used methods to measure hearing protectors attenuation can be divided into two categories: psychoacoustical (subjective) and physical (objective) methods. In order to better understand the relationship between these methods, this article presents various factors relating attenuation values obtained with these methods through a series of(More)
To enhance the communication experience of workers equipped with hearing protection devices and radio communication in noisy environments, alternative methods of speech capture have been utilized. One such approach uses speech captured by a microphone in an occluded ear canal. Although high in signal-to-noise ratio, bone and tissue conducted speech has a(More)

Noise reduction algorithms are nowadays used in multiple areas such as hearing aids, cochlear implants, telecommunication systems and hu-man/robot interaction devices. Issues with most of the current single channel noise reduction algorithms: • The use of a priori information for the estimation of the signal-to-noise ratio (SNR) or the noise parameters. •(More)
With the increase popularity of individual fit testing and miniaturization of electronic components, the Field-Microphone-In-Real-Ear approach (F-MIRE) is becoming more appealing and well suited for estimating hearing protection devices (HPD) attenuation both in laboratory and in "real world" occupational conditions. The approach utilizes two miniature(More)
Models for acoustic transducers, such as loudspeakers, mastoid bone-drivers, hearing-aid receivers, etc., are critical elements in many acoustic applications. Acoustic transducers employ two-port models to convert between acoustic and electromagnetic signals. This study analyzes a widely-used commercial hearing-aid receiver ED series, manufactured by(More)
Industrial workers are exposed to noise levels that could damage their hearing. The FieldMIRE (FMIRE) method has been developed to quantify earplug and earmuff attenuations with two microphones located under and outside of the HPD. This technique has been designed to be used in the field, but doesn't give a direct access to the noise exposure level, that(More)
1. ABSTRACT This paper will present the feasibility o f utilizing a miniaturized, real-time, in-ear, digital signal processing devices to investigate experience-dependent brain plasticity in the humans. An important component of this trial is the use of a recently developed digital hearing protector (from Sonomax, Montreal, QC) made with a custom earpiece(More)
