The July JASA Express Letters cover features figure 3 of “Design and simulation of acoustic vortex wave arrays for long-range underwater communication,” by Mark E. Kelly and Chengzhi Shi. The image depicts amplitude and phase distributions for two different arrays at ranges of 100 and 1000 m.

This month’s issue also includes two Editor’s Picks you don’t want to miss:

• “Sound power and acoustic efficiency of an installed GE F404 jet engine,” by Matthew A. Christian, Kent L. Gee, Jacob B. Streeter, Alan T. Wall, and Steven C. Campbell
• “Omega-K beamforming: Practical ramifications of alternative formulations,” by Timothy M. Marston and Daniel S. Plotnick

And, last but certainly not least, AIP published a new Scilight, “Membraned metasurface blocks noise but not air flow,” about the article, “Ventilated acoustic metasurface with low-frequency sound insulation,” by Yingxin Zhang, Yao Wei Chin, Xiang Yu, Milan Shrestha, Gih-Keong Lau, Boo Cheong Koo, Kun Liu, and Zhenbo Lu.

The June JASA Express Letters cover features an image of a simulated pressure field from figure 2 of “A three-dimensional active cloaking strategy for the Helmholtz equation that exploits the symmetry of the platonic solids,” Cheuk-Him Yeung, William J. Parnell, and Tom Shearer. The image depicts cloaked regions for various source distributions.

This month’s issue also includes three Editor’s Picks you don’t want to miss:

• “Joint trans-dimensional inversion for water-column sound speed and seabed geoacoustic models,” by Stan E. Dosso and Julien Bonnel.
• “Approximation of modal wavenumbers and group speeds in an oceanic waveguide using a neural network,” by A. Varon, J. Mars, and J. Bonnel.
• “Distributed acoustic sensing for detecting near surface hydroacoustic signals,” by Alexander S. Douglass, Shima Abadi, and Bradley P. Lipovsky.
