At this NAG meeting, Matt Blevins gave an update on the research project aimed at measuring the just noticeable difference of reverberation time, using an adaptive up-down procedure. Adam Buck had previously conducted a full study on 30 subjects using white noise bursts; Matt has been extending the work by on a smaller group of subjects with only 1000 Hz band-limited noise. So far, the results appear to be the same. He’ll be presenting on this work at the upcoming International Symposium on Room Acoustics (ISRA) in Toronto, June 2013. As for the fun acoustic nugget, we shared the news that Mayor Bloomberg in NYC has been targeting loud music through earbuds – a worthy endeavor, in our opinion!
