Control of Air Distribution Noise in Critical Auditoriums
Robert M. Hoover · The Journal of the Acoustical Society of America · 1967
To achieve low background noise levels in critical air-conditioned auditoriums, such as concert halls, it is essential to control the noise generated by air flow through air outlets and in terminal distribution ducts. In this paper, the air distribution systems of several auditoriums, and the corresponding background noise levels, are examined to help define appropriate noise-control measures for the design of silent air distribution systems. In addition to the evaluation of several existing air distribution systems, laboratory noise data on various types of air outlets are presented and related to field results.
