We are proud to announce that Glenn Leembruggen (Principal of Acoustic Directions) was awarded the 2021 Peter Barnett Memorial Award for his contributions to the acoustics and electro-acoustics industries.Presented by the Institute of Acoustics (IOA) in the United Kingdom, this award recognises advancements and technical excellence in the fields of electro-acoustics, speech intelligibility, and education […]
Osborn Fong recently presented a section for Supawood’s webinar “Certified Compliance for Peace of Mind”. He addressed the importance of acoustic compliance when designing and specifying internal lining and framing products. He also delved into the potential pitfalls of using a single number rating when describing the performance of an acoustic product, the benefits of […]
We are delighted to announce that Acoustic Directions and PKA Acoustic Consulting have been awarded the winners of the 2021 Hugh Vivian Taylor Award for their work on The Passive Noise Guide for the City of Sydney. This guide was developed to explore how natural ventilation in apartment buildings could be achieved, while also providing […]
Glenn Leembruggen recently gave a presentation at the Australian Acoustical Society (AAS) Making Waves 2021 Acoustic Conference in Wollongong. His presentation delved into the process of accurately predicting patron noise levels in restaurants and bars using an extension to J.H Rindels’ calculation method. Glenn’s study explored both small to medium sized restaurants, and large bistro […]
While we are missing the social dining-out experience and have to make do with limited take-away-only menus and higher prices, let us take a minute to consider one of the things that we do not miss so much about some dining out experiences. Noise. We are extremely fortunate that we are usually spoilt for choice […]
What to consider when installing hard floors in Stata Building: Strata By-Laws: Each apartment building will have its own strata plan and associated by-laws. Often older by-laws may have a simple clause such as “any new floor should be covered or otherwise treated to an extent sufficient to prevent the transmission from the floor space […]
Glenn recently presented a paper to the Institute of Acoustics in Bristol, United Kingdom at the Reproduced Sound Conference on the relationship between frequency response and the speech transmission index. The key point to take away from our research and presentation is that when specifying or commissioning an emergency sound system in a road tunnel, […]
Proper acoustic design in educational facilities is ever more crucial as open-plan, technology-filled “innovative learning environments” (ILEs) become increasing commonplace. Proponents of this current trend laud the flexibility provided by these open spaces, but sceptics doubt the effectiveness of these spaces due to various reasons, including the lack of consultation with teachers before implementation and […]
There are many different factors which affect the acoustic design of a classroom. Current research undertaken by Macquarie University and National Acoustic Laboratories Australia1 indicates that: Students spend approximately 45-60 % of their time listening and comprehending their teachers’ instructions. High levels of noise which mask and distort the teacher’s voice dramatically reduce speech intelligibility. […]
How many people are missing out on key bits of information in daily communication? We thought we heard Neil Armstrong’s famous words “one small step for man” where as Neil is adamant he said, “one small step for A man”. Poor intelligibly is how problems begin in video conferencing situations. Key bits of information just […]
