Proceedings of the Workshop on Acoustic Attenuation Materials Systems
Abstract
The choice and use of materials for acoustical attenuation is an important technical problem as well as of great interest for improving comfort and working efficiency. Although the major effort in this field is at ambient conditions and in the audio frequency range, there are important applications that involve widely varying pressures, temperatures, and frequencies along with other requirements peculiar to the particular use. Among current problems in the control of acoustic energy are those associated with such diverse applications as ultrasonic devices, space vehicles, and deep-diving oceanographic vehicles. Each of these, of course, may also have other quite different requirements of the acoustical materials in such properties as density, pressure responses, and flammability.
