National Acoustic Laboratories

1330 - 1800 Thursday 26 August  

At 13.30, a bus will depart from the Sydney Exhibition Centre at Darling Harbour for a conducted technical tour of the National Acoustic Laboratories (NAL) at Chatswood, Sydney on the northern side of the Sydney Harbour Bridge.

This elaborate complex of Reverberation Rooms and Anechoic Rooms was designed by German engineers and built in the early 1970’s, but is still of state of the art and in continual use for acoustic testing of materials and research into Hearing Acuity, Hearing Loss and Hearing Aid Research. We will split into small groups to tour the Reverberation Rooms and Anechoic Rooms within the Sound Shell and an overview of the acoustical testing that is being conducted that day.

The groups will also visit the Hearing Acuity, Hearing Loss and Hearing Aid research rooms. All groups will rejoin in the Lecture Theatre at 3.45 pm for tea/coffee and Dr Harvey Dillon, Director of Research, will provide an overview of the current NAL research into hearing assessment, improved hearing aids, clinical methods for hearing rehabilitation and prevention of hearing loss. There will be opportunities for questions and discussion. Return to Darling Harbour is scheduled for 1800. 

There is no charge for this special technical tour but there is a limit to 60 persons in total.

Tours of the Opera House are also offered every day at 11.00 and can be booked via the day tours program.  Click here  for details. 

The iconic sail-like shape of the roof of the Sydney Opera House, designed by the Danish architect Jorn Utzon, overlooks the beautiful Sydney Harbour and covers a complex of six auditoria and about 800 other rooms. The two main entertainment areas are the Concert Hall which seats 2,678 and the Opera Theatre which seats 1507, the room acoustics for each being quite different and well-suited to their purpose.

The tour (from 3 to 5 pm) will divide into three groups and be conducted behind the scenes with special emphasis on the acoustic structures, acoustic problems that have been encountered and plans for improvement.

There is no charge for this special technical tour but there is a limit to 60 persons in total.
