NAG Meetings 1-28-15 and 2-11-15

At our first NAG meeting of the year on 1-28-15, Joonhee Lee presented our newly acquired Larson Davis 831 sound level meters to the group – what an improvement over the 824s!  We had two acoustic nuggets, one youtube video (oldie but goodie) showing what an iPhone recorded inside a guitar and the other on Trevor Cox’s recently published text “The Sound Book“.  Madeline Davidson also shared the amazing Cycloramic iPhone app, as featured on the TV show Shark Tank (you must try it).  At our 2-11-15 NAG meeting, Matt Blevins discussed work that he’s been conducting on optimizing transmission loss of metamaterials using genetic algorithms.  We again had two acoustic nuggets to share.  The first from Matt Easlon shows how there are now techniques to create earmolds without touching your ears.  Joonhee Lee shared one that he recently found on how the architect of the new Philharmonie de Paris is boycotting the opening of his hall, stating that it is not complete (because of lack of acoustical tuning among other things!)  Here’s a link to a great panoramic view of that space.

‘People Behind the Science’ Podcast: Dr. Lily Wang

Dr. Lily Wang was featured on a recent podcast, ‘People Behind the Science’, as interviewed by host Dr. Marie McNeely.  If you have 47 minutes to spare sometime, take a listen (… although Dr. Wang admits she hasn’t had the nerve to listen to it herself yet!!)

NAG Winter Party 2014

Happy holidays from NAG!

Happy holidays from NAG!

The annual Nebraska Acoustics Group Winter Party was held on Wednesday, December 17, 2014.  The party featured food from Famous Dave’s, a game of ‘Holiday Bingo’ (to determine the order of opening gifts), and our traditional ‘white elephant’ gift exchange.  The reindeer glasses were a hit this year, as shown in our annual group photo.  Hope that everyone had a great holiday!

Dr. Lily Wang and two PhD students (Zhao ‘Ellen’ Peng and Joonhee Lee) presented technical papers at Internoise 2014 in Melbourne, November 16-19, 2014.  Both Ellen and Joonhee received Young Investigator Travel Grants to attend the conference.  The conference was a great networking opportunity, particularly with acousticians from Australia, Asia, and Europe.  Here is a photo of the three NAG members before attending a concert at Hamer Hall in balmy Melbourne.  It was great to see other familiar faces, including Craig Dolder who posted on his blog about the conference.

NAG Meetings 11-12-14 and 12-3-14

At the 11-12-14 NAG meeting, Brent Kraay presented on the MAE project he is working on under Dr. Ryherd’s advisement, involving sound level measurements taken at NICU units in hospitals.  At the last NAG meeting of the semester on 12-3-14, Sungbeen Cho presented a project that he worked on as an acoustical consultant in Korea, prior to joining UNL, Solgaram Art Hall.  The acoustic nugget focused on a new method that allows ultrasound to penetrate bone and metal.  We also excitedly reported that we are taking advantage of Larson Davis’ offer to trade in our 824 sound level meters for the newer 831 models – just in time for the holidays!

We have been delinquent in updating our blog – sorry about that!  It’s time to catch up, as lots has been going on with our group over the last few months.  A number of NAG members participated in the last ASA conference in Indianapolis (October 2014); we presented three technical papers and two undergraduate posters.  Notably, both undergraduate poster presenters won Undergraduate Poster Awards – congratulations to Brenna Boyd and Laura Brill (from Nebraska Wesleyan, advised by NAG PhD student Matt Blevins)!  Other highlights of the conference included: singing a capella with other interested ASA attendees on Monday night; NAG Halloween Party after the ASA social on Thursday evening during which many NAG members dressed up (and won costume awards at the social!); and hanging out late in the evening playing Resistance and Avalon.  Check out additional photos on our Picasa webpage.

NAG Meetings 10-8-14 and 10-22-14

At our 10-8-14 NAG meeting, Brenna Boyd presented on the summer research she conducted under Ellen Peng’s mentorship, on “Analysis of Subjective Perception Results from Speech Comprehension Studies”.  Brenna will be presenting this work at the upcoming ASA meeting (her first!) in the Undergraduate Research Poster session.  The highlighted Acoustic Nugget was one posted recently by IFL Science!, on “Does My Voice Really Sound Like That” which links to a great short video on the topic.  At the 10-22-14 NAG meeting, Madeline Davidson discussed the work she had done as a summer intern at Trane, on qualifying their hemi-anechoic chamber.  We highlighted another cool web link (an Animagraff!) that shows how loudspeakers work, shared with us by alum Andrew Hathaway.  Many of us are looking forward to the upcoming ASA meeting in Indianapolis … we’re planning a Nebraska Acoustics Group Halloween Party on Thursday evening, after the TC Noise meeting – many of us will be in costume!  We’ll be sure to post a photo after the event…
