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:

• From Physical Acoustics, “Wind turbine sound propagation: Comparison of a linearized Euler equations model with parabolic equation methods,” by Jules Colas, Ariane Emmanuelli, Didier Dragna, Philippe Blanc-Benon, Benjamin Cotté, and Richard J. A. M. Stevens.
• From Speech Communication, “Generalized perceptual adaptation to second-language speech: Variability, similarity, and intelligibility,” by Ann R. Bradlow, Adrianna M. Bassard, and Ken A. Paller.
• From Underwater Acoustics, “Observations and simulations of caustic formation due to oceanographic fine structure,” by Jacob P. DeFilippis, Bruce D. Cornuelle, Andrew J. Lucas, William S. Hodgkiss, Luc Lenain, W. A. Kuperman, and Matthew H. Alford.
