Overview of the revision of AS/NZS 2107

On behalf of its members, the Australian Acoustical Society was the lead organisation in the application to Standards Australia in 2013 for a project on the review of AS/NZS 2107 “Acoustics—Recommended design sound levels and reverberation times for building interiors”. The basis of this request was that the version from 2000 needed updating to revise the text, include more spaces relevant to the current building designs, remove spaces that are no longer relevant and revise the levels for both design sound levels and reverberation times. The project was approved by Standards Australia and the committee commenced the work. A draft was sent out for public review and almost 500 comments were submitted highlighting the importance of this standard to the acoustics community in Australia and New Zealand. Many of these comments were common indicating that discussion on the draft had been undertaken by groups; another good sign. A two day meeting was held in March 2015 for the committee to go through the comments and amend the draft as necessary to produce a final version. The revisions aim to maintain the same intent for what is clearly a well-respected and important document. In this paper an overview will be provided of the process and changes that have been made in the standard.
