Sound Perspectives
8 The Mammalian Ear: Physics and the Principles of Evolution – Geoffrey A. Manley, Andrei N. Lukash-
kin, Patrício Simões, George W. S. Burwood, and Ian J. Russell
Physical laws govern the operation of the ear but natural selection dominates its design.
17 The Inaudible Rumble of Volcanic Eruptions – Robin S. Matoza and David Fee
57
Committee on International Research and Education – Ann Bradlow and Michael Vorländer
Volcanic eruptions produce powerful infrasound that can be used to monitor and mitigate volcanic hazards.
26 Exploring the Ocean Through Soundscapes – Jennifer L. Miksis-Olds, Bruce Martin, and
Peter L. Tyack
Listening to underwater soundscapes helps us understand how ocean physics and the biology of marine communities are responding to a dynamically changing ocean.
35 Floyd Dunn and His Contributions to Biomedical Ultrasound – William D. O’Brien, Jr.
There were a few years in the 1960s when Floyd Dunn almost single-handedly managed to keep biomedical ultrasound alive.
42 Soundscape Ecology of the Anthropocene - Hans Slabbekoorn
Noisy human activities change natural soundscapes. This not only affects the health of people but also acoustic communication in animals.
50 The Acoustics of Woodwind Musical Instruments – Joe Wolfe
The oldest known instrument family produces a wide range of tone colors and pitch using a range of interesting physics.

About The Cover
Explosive eruptions are seismo-acoustic phe- nomena, generating large-amplitude acoustic (infrasound) and seismic waves. These signals are produced as magma fragments (breaks into small pieces called pyroclasts), and pyroclasts are ejected explosively as impulsive blasts or sustained turbulent flows through volcanic vents and craters.
