Fall Issue 

We try to have wide-ranging content in Acoustics Today (AT), with the goal of having material that all members of the Acoustical Society of America (ASA) will find interesting, and from which they might learn about interesting things outside of their specialized areas. This issue is no different both in terms of species (fishes, humans, insects) and topics covered, although the brain is a part of several of the articles.

Past issues of AT have covered sound production mechanisms in many species (see bit.ly/ATC-Bioacoustics) but never in fishes. In our first article, Michael L. Fine and Eric Parmentier write about this fish sound production. Interestingly, acoustic communication arose early in the evolution of fishes (and thus of vertebrates). While many readers are familiar with sound production mechanisms that involve the movement of air (e.g., in mammals), the mechanisms involved in fish sound production are fascinating and quite different, and often involve a variety of different body parts.
