7 Soundscape: An Approach to Rely on Human Perception and Expertise in the Post-Modern Community Noise Era—
Brigitte Schulte-Fortkamp, Bennett M. Brooks, and Wade R. Bray
Soundscape is a powerful new tool for the measurement, analysis, and design of environmental and community noise, which applies the knowledge of both science and built-in experts.
17 Alien Soundscapes: A Concise Guide to the Atmospheric Acoustics of Venus, Mars, Titan, and Earth—
Andi Petculescu and Richard M. Lueptow
The Huygens mission to Titan boasted both passive and active acoustic sensors—a first in space exploration. Acoustics can probe extraterrestrial environments in many ways ranging from atmospheric structure to sur- face topography, and, looking ahead, to infrasonic stud- ies and anemometry.
23 Underwater Ambient Noise—
Peter H. Dahl, James H. Miller, Douglas H. Cato,
Rex K. Andrew
What are the major anthropogenic and natural con- stituents of underwater ambient noise, and can a com- parison be drawn between the undersea soundscapes of marine mammals and human ambient noise environ- ments on land?
35 The Acoustics of Floors in Condominiums— Marshall Long
Minimum code compliance does not necessarily yield acoustical privacy. Minimum code construction is so bad that there “ought to be a law” against building it any worse.
