The annoyance caused by airplane noise can have adverse effects on those living near airports. Can anything be done when the plane lands to mitigate the noise? In this episode, we talk to Anders Johansson (Royal Institute of Technology, Sweden) about his research into how airplane configuration and weather may affect landing noise.

Researchers know that bats will alter the calls they use for echolocation depending on their task or environment. In this episode, we talk to Léna de Framond and Holger R. Goerlitz of the Max Planck Institute for Ornithology about their research into whether bats from temperate regions, which experiences large variations in temperature and humidity which could affect call attenuation, vary their calls based on weather.

The June cover of JASA is now available and it features exciting new research from this past month!
The cover image is two panels from Figure 11 of “Simulation of acoustic reflection and backscatter from arctic sea-ice,” by Nicholas P. Chotiros, Gaye Bayrakci, Oliver Sanford, Timothy Clarke, and Angus I. Best. Editor-in-Chief James Lynch says about the feature article:
About thirty-five years ago, I (Jim Lynch, JASA EIC) worked on acoustic scattering from sea ice in the Nordic Seas, so sea ice scattering is a topic that I personally find interesting. One of the harder problems associated with sea ice is to determine its mechanical and acoustic properties over a large area. Upward looking sonars are one very useful technology to do that. Occasional, very expensive upward looking sonar surveys by submarines were employed thirty-five years ago, but these are too costly and hard to arrange to consider as a routine measurement technique. However, in the intervening years, autonomous underwater vehicle technology has developed to the point of being routine, and sonar sensors are commonly part of the sensor suites they carry. In Nick Chotiros’ article, simulations are made of how well such vehicle plus acoustics systems will perform in characterizing sea ice for a survey. Ocean acousticians always dream of having turnkey operations where our robots do the heavy lifting while we sit back and drink coffee, and this article discusses what may be just such a system.

The May covers are now available and feature exciting new research from this past month!
The JASA cover features a few panels of Figure 5 from “Source localization based on steered frequency–wavenumber analysis for sparse array,” by Y. H. Choi, J. S. Kim, and Gihoon Byun. The images depict results of waveguide simulation in the environment of SAVEX15, a shallow-water acoustic variability experiment conducted in May 2015.

The JASA Express Letters cover features an image of a simulated pressure field from figure 2 of “Transcranial ultrasound simulation with uncertainty estimation,” by Antonio Stanziola, José A. Pineda-Pardo, and Bradley Treeby. (Browse the rest of the issue at https://pubs.aip.org/asa/jel/issue/3/5.)
Noise can damage hearing in numerous ways: hearing loss, tinnitus, difficulty hearing in noisy settings, as well as other sound detection or sound processing deficits. In this episode, we talk to Colleen Le Prell (UT Dallas School of Behavioral and Brain Sciences) and Odile Clavier (Creare), two editors of the recent Noise-Induced Hearing Disorders Special Issue of JASA. Learn about current clinical and investigational tools for studying noise-induced hearing disorders, as well as the latest on research about noise monitoring and hearing protection.
