We previously wrote about our work on deep neural networks for speech enhancement. In late August, we presented our newest results as a paper and a poster at the speech technology conference Interspeech 2017 in Stockholm, Sweden.
The 39th Scandinavian Symposium on Physical Acoustics was held at Geilo, Norway from January 31 to February 3, 2016. It was organised by Ulf Kristiansen and Erlend Magnus Viggen, both part of the Acoustics Research Centre. This year we had 48 participants holding 31 presentations, and 9 papers were written for the proceedings, which have been published through arXiv.org.

In the MAUS project, we have developed a prototype of a traffic auralisation tool. The idea is to realistically imitate the sound of traffic, to give an idea of how it will sound in cases that have not been realised yet, and to show the effects of various noise-reducing measures. We have previously given a simple description of how the tool works together with sound examples on this blog.
In early December, we presented a paper and a poster on the MAUS auralisation tool at the 18th International Conference on Digital Audio Effects (DAFx-15) here in Trondheim. This conference was organized by the Music Technology and Acoustics groups at NTNU.
The annoyance response of different communities to aircraft noise has always been difficult to predict. However, in recent years, many studies report extremely high levels of annoyance for the given noise exposure levels. This has led to the belief that people are nowadays less tolerant to aircraft noise than they were a few decades ago.
We’ve looked at the results of 57 aircraft noise surveys conducted between 1961 and 2015, and found that people’s tolerance to aircraft noise hasn’t changed at all.
