of hearing and listening abilities in young children is studied
through projects that address how normally developing children
process auditory information and how those abilities change with
maturation. Other studies include how processing may be
disrupted in children with language and/or learning disorders,
how auditory and learning skills may be affected by poor
acoustic environments, and how performance on behavioural tests
correlates with physiologic development as derived from evoked
Current research in the Child Hearing Research Laboratory is
examining auditory processing
disorders in school-aged children.
Using advanced audiologic diagnostic methods that employ
both behavioural and electrophysiological technologies were are
examining supra-threshold function in children with no evidence
of hearing loss.
These children have normal hearing sensitivity but significant
problems in learning through the auditory modality and in
processing auditory signals such as speech in difficult
Complementing that work is our research in developmental
psychoacoustics. By understanding the development of normal
auditory skills we can better understand how children acquaint
themselves with their auditory world and learn using their
hearing. By mapping
normal auditory development as it proceeds from preschool
through the school-aged years we are in a better position to
meet the auditory learning needs of normally developing children
as well as assess the auditory skills of children with learning
difficulties and avoid confusing maturational delays with
Other research focuses on the impact of noise on
children’s academic abilities including
reading and vocabulary development.
The process of
selecting and fitting hearing aids and assistive listening
devices for infants, toddlers, and children is a focus area of
the Child Amplification Laboratory. Improved techniques
for relating the hearing test to hearing aid fitting, and for
measuring and prescribing hearing aid performance are studied.
developed are now being applied to select and fit hearing aids
in clinics throughout the world. The results of this research
are disseminated to the broad community of audiologists and
hearing aid specialists through scientific publications and the
distribution of the Desired Sensation Level (DSL) software
system and method for hearing aid prescription and fitting.
