Scientific Acoustics gets intensive with EASE
Published: ASIA
AUSTRALIA: Scientific Acoustics is bringing an intensive four-day EASE and EASERA training programme to Canberra in June. Taking place at the Eastlake Football Club on Oxley Street in Kingston, the course will be led by Tim Kuschel and Peter Patrick with support from EASE manufacturer, AFMG. As long-time EASE power users and Beta testers, Mr Kuschel and Mr Patrick have previously conducted four highly successful seminars across Singapore and Australia. The sessions in Canberra will be a mixture of theory, hands-on and live demonstrations focussed on real-world design techniques.
This year’s programme will comprise an intensive three-day, one-evening class seminar followed by a morning tour of a Canberra house of worship on the fourth day. The daytime sessions will concentrate on the EASE platform using presentations developed by AFMG staff in addition to contributions by Mr Kuschel and Mr Patrick. Topics will range from an introduction of the basics of the software, such as building a model in EASE from scratch, to more advanced topics such as detailed mapping features, ray tracing, speaker cluster building and key acoustic principals. Each student will be given a full time limited version of EASE for the duration of the course.
The evening class will concentrate on loudspeaker interaction and measurement. Demonstrations of interference between loudspeakers, acoustic coupling, windowed and non windowed measurements, as well as the effects of rooms on microphones, room modes and a number of interesting behaviours of loudspeakers, rooms and microphones will provide a sound basis for the second training day. Sessions will also be devoted to acoustic calculations and what the metrics mean. The key parameters of reverberation time, STI, and STIPa will be discussed and explained along with their influence on perceived sound and intelligibility. Additionally as part of the programme, David Murphy from Krix Loudspeakers will give a presentation exploring what goes into the design and manufacturer of a good loudspeaker, covering the measurement techniques used to gather EASE data and produce ‘clean’ frequency responses and the subsequent processing in SpeakerLab.
‘The course is designed to teach students about EASE modelling through a variety of real life demos – we measure the behaviour of different loudspeakers, pass around microphones showing how delays and echoes affect the listening experience, explain how to calculate STIs and reverberation times and discus the Australian and New Zealand standards that affect our work,’ explained Mr Patrick. ‘The course then ends with a half day visit to a challenging project so everyone can see the installed system, see how the modelling worked and hear the results.’
A complete day and evening schedule for the programme is available on the Scientific Acoustics website.
