Acoustics Today
A Publication of the Acoustical Society of America
Volume 5, Issue 3 July 2009
Cover: Army personnel are required to perform missions while immersed in a wide range of ambient sounds. Acoustic recreations of rural and urban soundscapes mixed with relevant military sounds need to be presented to warfighters in controlled laboratory spaces to quantify the effects of auditory environments on listening tasks. For this reason, the Environment for Auditory Research (EAR) facility was conceived and constructed at the U.S. Army Research Laboratory (ARL) at Aberdeen Proving Ground, Maryland. This new facility will be used to study the ability of soldiers to detect, identi- fy, and localize sounds in realistic operational sound fields and to develop equipment to maximize human communication performance.

9 The Environment for Auditory Research—
Paula P. Henry, Bruce E. Amrein, and Mark A. Ericson
A world-class facility for auditory research has been cre- ated at the U.S. Army Research Laboratory.
17 The Sound of Music and Voices in Space Part 1: Theory—Timothy G. Leighton and Andi Petculescu
27 The Sound of Music and Voices in Space Part 2: Modeling and Simulation—Timothy G. Leighton and Andi Petculescu
Practical acoustic sensing in alien atmospheres must involve a thorough understanding of the generation and propagation of sound in the respective environments.
31 What is the Sound of the Eiffel Tower?—China Blue Listening to the Eiffel Tower provides us with new infor- mation about the acoustics of structures.

39 Standards: Clarification of Some Hearing Aid Terminology: Bands and Channels versus Handles. First-order Versus Second-Order Microphones.— Ruth A. Bentler and Barbara Kruger
Terminology is often more elusive than the technology it
explains. Having some consensus in the wording for both industry and the practitioner may be the key to better communication between those two important entities.
