Labs and Core Facilities

Anechoic Chamber and Laboratory 

The Beltone Anechoic chamber, one of the largest in Ontario, enables researches to study sound propagation in simulated 3D environment. With a computer controlled 64 speaker array, the sound processing capabilities of instruments and people is being measured in a simulated real-world environment. It allows researchers to study binaural hearing and the processing of signals in noise. [more]

Assistive Devices Laboratory 

The Assistive Devices Laboratory is equipped with the latest in assistive technologies for persons who are deaf, deafened, and hard of hearing. This lab is used in Adult Aural Rehabilitation research, student training, and for assistive device consultation through the H.A. Leeper Speech & Hearing Clinic. Supported by Bernafon Canada. [more]

Child Amplification Laboratory 

The Child Amplification Laboratory undertakes research relating to the process of selecting and fitting hearing aids and assistive listening devices, with a particular focus on children. Their work on early detection and habilitation of hearing impairments has been instrumental in the development of Infant Hearing Programs. [more]

Child Hearing Research Laboratory 

The Child Hearing Research Laboratory includes a full sized sound booth and equipment for stimulus and experimental control. Using both custom developed and commercially available software they are able to test the psychoacoustic abilities of preschool- and early school-aged children as well as adults. [more]

Digital Signal Processing Laboratory

The Digital Signal Processing (DSP) Laboratory undertakes research projects related to speech and audio processing with applications in hearing aids, assistive listening devices, and augmentative communication devices. Current research activities  include objective measurements of speech and audio quality, development and evaluation of speech enhancement algorithms for digital hearing aids, and evaluating the interaction between speech coder quality and hearing loss, especially in Voice over Internet Protocol (VoIP) communications.

Hearing Research Clinic 

Not only a child’s ability to hear sounds, but also their ability to understand them, has been a focus of research in the GN Otometrics Child Hearing Research Lab and the Siemens Clinical Research Lab. Using behavioral and objective techniques, the work has the potential to change diagnostic audiology and contribute significantly to the understanding of auditory development and function. [more]

Hearing Science Laboratory 

The Hearing Science Laboratory research focuses on temporal processing in older normal hearing adults and contributes to changes in the assessment of hearing in adults and in the management of their hearing health care. Through better understanding of the effects of the aging ear on hearing, hearing health care to older listeners is being improved. [more]

Robert B. Johnston Aural Rehabilitation Laboratory 

A major focus of work in the Robert Johnston Aural Rehabilitation Laboratory is examining the facilitators and barriers to assistive device use. Ways to prevent and alleviate the debilitating effects of hearing impairments on social functioning are studied, as well as how to assist those persons with hearing impairments by using a wide range of listening devices. [more]

Advanced Diagnostics Laboratory

The Communication Laboratory supports research to improve our knowledge of how humans learn, understand and use spoken language. [more]

Speech, Auditory Feedback, and Electrophysiology (SAFE) Laboratory

The Electrophysiology Laboratory contains a new, RF shielded sound booth and spacious work and equipment areas. These facilities are used in the simultaneous stimulation of acoustic responses from the cochlea (otoacoustic emissions) and electrical responses from the auditory nervous system (auditory evoked potentials). This research enables us to better describe a variety of auditory disorders including cochlear hearing impairment, auditory neuropathy, and auditory processing disorders. [more]
