National Acoustic Laboratories

The National Acoustic Laboratories (NAL) is the research division of Australian Hearing. Since 1947, NAL’s research into hearing and noise has improved the help available for people with hearing loss.

It is a world leader in research on hearing assessments, preventing hearing loss and rehabilitating people with hearing loss.

A team of about 40 people investigate all things hearing-related, aided by numerous volunteers from the public. NAL’s purpose is not only to create methods of rehabilitation, but also prevention of hearing loss.

It produces research publications, shares information on its website, and participates on talks and conferences, aimed at helping the industry and society as a whole.
