Dr Michael Fisher

Role: Project Leader

Michael Fisher is a Senior Research Engineer at the National Acoustic Laboratories where he has worked since 1994. He has Bachelor of Communications Engineering (honours) from RMIT University and has recently submitted his doctoral thesis titled ‘Speech referenced dynamic compression limiting: Improving loudness comfort and acoustic safety. Michael researches and develops methods of improving hearing loss prevention, assessment and rehabilitation. His speciality is audio signal processing. Michael has developed a number of audio signal processing algorithms and holds several patents for these. The most known of these are in the SoundShield™ acoustic shock protection device for headset users including HEARworks Shriek RejectionTM algorithm

In parallel with his work at NAL Michael spent many years running a post-graduate course in digital audio at the University of Sydney where he also lectured in auditory physiology and psychoacoustics. Prior to this Michael ran an undergraduate course in digital audio at RMIT University and has been a broadcast engineer, a sound engineer and a rock group manager. His current professional interests include the Speech Referenced Limiting noise control method, noise reduction for personal sound devices, loudness perception and sound intensity control, acoustic startle and acoustic shock, spatial perception and pitch perception.
