October 2023 JASA Cover

The October cover of JASA is now available and it features exciting new research from this past month!

The cover image is from Figures 8 through 11 of “Apparatus for three-dimensional emission pattern estimation of acoustic emitters,” by Alberto Yoshihiro Nakano, Artur Adolfo Falkovski, Mayconvorgel Ibrahim Ribeiro, and Felipe Walter Dafico Pfrimer.  Editor in Chief Jim Lynch says about the feature article: The 3-D directional pattern of an acoustic emitter is a key piece of its characterization, but not so simple to obtain with simple equipment and processing. In the article by Nakano et al, a relatively simple single sensor device mounted on a circular swivel is described, which allows very precise measurements to be made. The measurement is slower than a 3-D spherical enclosure, but has a great advantage in simplicity and cost.

Some other research was also highlighted on the October JASA cover:

All the articles from the cover are free to read for a month after the cover is released, so be sure to check them out! You can find the whole issue at https://pubs.aip.org/asa/jasa/issue/154/4.

Popular Social Media Posts – October

It’s that time of the month where we take a look at some of our popular publications social media posts on Facebook, Instagram, X (Twitter), and LinkedIn. The following posts got people to like, share, save, and perhaps most importantly, read the published research!
On the ASA Facebook page, a Proceedings of Meetings on Acoustics (POMA) post featuring “Modeling the sound radiation of gamelan gongs using analytic rigid spherical models” got shared quite a bit. You can visit the post first or read the article at https://doi.org/10.1121/2.0001754.
Users on Instagram really liked the loudspeaker array from “Sound field synthesis for psychoacoustic research: In situ evaluation of auralized sound pressure level” published in The Journal of the Acoustical Society of America (JASA). You can like the IG post or go check out the entire article at https://doi.org/10.1121/10.0021066.

Then, on Linked In, the Acoustics Today (AT) collection covering Human Psychoacoustics piqued users’ interest. Leave your own reactions on the post or check out the articles at https://acousticstoday.org/at-collections-human-psychoacoustics/.
Over on the JASA Express Letter X (Twitter) account, the post featuring the Editor’s Pick, “Higher-order mode filtering by a resistive layer” got a lot of love. See the original tweet here or skip straight to reading the article at: https://doi.org/10.1121/10.0021283.

New Across Acoustics Episode: Considering Classroom Soundscapes for Young Students

The sound environment of a classroom can significantly impact the experience of students, particularly for young learners. Yet most research on primary school classroom acoustics has focused solely on removing all sound, even though some sounds may be beneficial to young students’ experience. In this interview, we talk to Chiara Visentin (University of Ferrara) about her research into the soundscape of primary school classrooms.

Smartphone Apps and Acoustics

During the 174th ASA Meeting in New Orleans, Louisiana, Gregory S. Farber and past president Lily M. Wang reported on an exploratory, large-scale noise survey of sound levels of restaurants and bars in New York City using an app called SoundPrint. The related proceedings paper* states that SoundPrint encourages the public to collect and crowdsource sound level data. Furthermore, this information can help users visit locations based on their loudness (or quietness).
SoundPrint - acoustic apps
Since publishing, Farber has started a campaign to promote hearing health called the SoundPrint Find Your Quiet Place Challenge. Beginning October 1, 2023, participants are asked to take sound measurements and submit them to the SoundPrint database. The collection of sound level data will enable SoundPrint to advocate for safe noise levels, help communities find quieter places, and protect the public’s hearing health. Participants can even win prizes! For complete details, visit the FYQP webpage.
NoiseCapture - acoustic apps
Want to explore further? Other tools and apps crowdsource sound data and educate people about acoustics. For example, the NoiseCapture app lets anyone measure their sound environment and share their geolocated measurements with the community in order to build a collective noise map. In The Journal of the Acoustical Society of America (JASA) article, NoiseCapture smartphone application as pedagogical support for education and public awareness, authors describe how the app was used in educational settings to help students and teachers learn the basic knowledge of environmental acoustics and noise mapping.
NIOSH - acoustic apps
You might be curious if smartphone apps are actually good enough to gather such sound data. Researchers at the National Institute for Occupational Safety and Health (NIOSH) had similar questions resulting in two JASA publications about the accuracy of smartphone sound measurement applications; Evaluation of smartphone sound measurement applications and Evaluation of smartphone sound measurement applications (apps) using external microphones—A follow-up study. These studies, along with others, lead NIOSH to create the NIOSH Sound Level Meter App, which measures occupational noise exposure similar to professional instruments.

Let us know if you use any of these apps or other acoustics apps on your phone!

September 2023 JASA Cover

The September cover of JASA is now available and it features exciting new research from this past month!​
The cover image was inspired by “Aeroacoustic performance of a seal vibrissa shaped cylinder,” by Tom A. Smith, Guanjiang Chen, and Bin Zang.  Engineering Acoustics Coordinating Editor Dan Costley says about the feature article: I like this article because it is novel and multidisciplinary. The authors investigate a bio-inspired shape to reduce flow noise.

Some other research was also highlighted on the September JASA cover:
