How tonality and loudness of noise related to annoyance and task performance

The April 2017 issue of Noise Control Engineering Journal includes a paper by alums Dr. Joonhee Lee and Jennifer Francis with Dr. Lily Wang on “How Tonality and Loudness of Noise Relate to Annoyance and Task Performance”! The article presents results from Joonhee’s PhD work at the University of Nebraska, in which a multiple regression model was developed for predicting annoyance responses from tonal noise conditions using two of the most strongly correlated noise metrics, ANSI loudness level and tonal audibility. We have plans to publish more from Joonhee’s work soon – be on the lookout!

NAG Meetings 3-13-17 and 4-17-17

At the 3/13/17 NAG meeting, Stephanie Ahrens reviewed the work she’s completed on worship space acoustics based upon the recent ASA publication, co-edited by Dr. Erica Ryherd and two other NAG alums.  Stephanie’s work has been funded by a UNL Undergraduate Creative Activities and Research Experience grant.  The acoustic nugget discussed how global warming is changing how the ocean carries sound.  At our 4-17-17 NAG meeting, Anna Catton presented the entry that she and Brenna Boyd are working on for this year’s ASA Student Design Competition, to be judged at the upcoming Acoustics ’17 conference.  There were two recent in-the-news ‘acoustic nuggets’ presented, one on how it’s possible to hack a phone with sound waves, and the other on how even less expensive cars are now trying to work on reducing in-car noise.  (Dr. Wang has admitted bring sound level meters with her when shopping for vehicles!)

NAG Meetings 1-23-17 and 2-13-17

At our first NAG meeting of the spring semester, Dr. Wang reviewed various professional development opportunities in acoustics, such as becoming INCE Board Certified or getting a Professional Engineering license in acoustics.  The acoustic nugget was on the new Elbphilharmonic concert hall, which used parametric design principles – it is visually stunning!  At our 2-13-17 NAG meeting, Anna Catton reviewed recent acoustics investigations using 3D audio test facilities, which she studied for her fall 2017 independent study project.  The acoustic nugget featured news on there being a biological reason for misophonia (a disorder in which people hate sounds such as other people eating/chewing)!

NAG Winter Party 2016

Happy Holidays 2016 from NAG!

The annual Nebraska Acoustics Group Winter Party was held on Wednesday, December 14, 2016.  The party featured catered fare from Beacon Hills in Omaha, a game of ‘hot potato’ using a small stuffed reindeer (to determine the order of opening gifts), and our traditional ‘white elephant’ gift exchange.  Lily gave out red Rudolph noses (which would have seemed less clownish if we’d had antlers for everyone too?) , as shown in our annual group photo.  We wish all of our friends and colleagues from around the world a happy holiday season and all the best in 2017!

NAG at ASA/ASJ in Honolulu (November 2016)

Assorted NAG members and alums at ASA/ASJ Honolulu

A number of NAG members participated in the last ASA/ASJ joint meeting in Honolulu (28 November – 2 December, 2016).  Matt Blevins, Laura Brill, and Joonhee Lee all presented technical papers that were well-received.  There were a large number of NAG alums at the conference, many of whom stopped by NAG Board Game Night after the TCAA meeting on Tuesday – we particularly enjoyed the games ‘What’s Yours Like’ and ‘Splendour’!
