National Acoustics Laboratories releases hearing aid solution that overcomes effects of face masks on speech
The National Acoustics Laboratories (NAL) has developed a solution to a challenge
faced by hearing aid users worldwide in 2020 - the impact of face mask use on their
understanding of speech.
NAL, the research division of Hearing Australia, has issued recommendations for
audiologists across the world on how best to adjust hearing aids to counter the effect
of face masks for people who use hearing aids.
“Face masks are a powerful tool against the spread of COVID-19 but they also soften
speech sounds,” says Dr Brent Edwards, NAL Director.
“NAL’s recommendations are designed to help hearing aid users worldwide
communicate with people wearing masks. Now that we can share our evidence-based solution, we anticipate it will have implications nationally and internationally,
which is most exciting.”
Evaluation, involving computational models of speech and hearing as well as
laboratory speech tests, has proven that the adjustments help hearing aid users
understand speech just as well as when the speaker is wearing a mask as when they
are not.
NAL’s solution details specific adjustments that can be made to any type of hearing
aid to counter the effect of different types of face masks on speech sounds.
It follows
extensive research into the effect of face mask use on speech understanding and how
best to counter it.
Hearing Australia has already started implementing the solution in its centres across
Australia and this is proving popular among its clients.
“Our clients have indicated they’ve noticed a marked difference with NAL’s hearing aid
adjustments. They have improved their understanding of masked speakers while
having no impact on the sound of their own voice or other sounds,” says Emma
Church, Hearing Australia Audiologist.
“Restoring the ability to understand speech takes the stress out of everyday tasks like
shopping and attending health appointments; so we’re keen to spread the word about
our solution,” says Dr Edwards.
NAL’s recommendations have been released to audiologists worldwide and detail how
they can implement the adjustments to their patients’ hearing aids to allow them to
better understand people wearing masks.
