His aim was to make unwanted noise and vibration inaudible and good noise crystal clear. He qualified in electrical engineering and architecture at the University of Sydney and worked in underwater acoustics for the Royal Australian Navy, and for OTC, before establishing the consulting firm which he ran for 40 years. In 1970 he designed and developed the audio-tactile push-button signalling system for pedestrian crossings which is now used world-wide. Major infrastructure projects for which he provided acoustic designs include Parliament Houses in Canberra, Sydney, Brisbane and Port Moresby, and the Sydney Harbour Tunnel. Challis was specialist advisor on the forensic assessment of tapes for ASIO and the New South Wales Government. His work was recognised with a number of awards including 12 Engineering Excellence awards from Engineers Australia and Consult Australia. 1966 2006 Career position - Director, Louis A.
