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]

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]

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]

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]

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.

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]

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.
