Acoustic Shock Protection 

NAL and the Cooperative Research Centre for Cochlear Implant and Hearing Aid Innovation have developed a sophisticated device to help protect call centre telephone operators against acoustic shock.  The device also improves intelligibility and listening comfort.  It uses digital signal processing to tailor the sounds present at the eardrum.  The commercial product, called Sound Shield^TM, won the Award for Technology Transfer at the Cooperative Research Centre Association Conference on 22 May 2002.

Patents

We have established a priority date and are in the process of patenting several different micro-machined microphones.

We have also established patents and working prototypes for a noise-robust adaptive directional microphone array.

The devices are primarily designed for hearing aid use but may have other applications.  Any parties interested in the above, especially with a view to commercialization, may like to contact George Raicevich at:  george.raicevich@nal.gov.au
