A quiet success - Caterpillar's noise control research lab

From: Sound and Vibration | Date: February 1, 2003| Author: | Copyright information

Caterpillar recently completed a new noise control research laboratory. Through careful planning and coordination, the lab was designed and constructed in about a year and, most importantly, the lab's sound chambers - a reverberation chamber and a hemi-anechoic chamber - met all functional acoustical performance design goals. This article is an overview of the lab and its construction, covering the steps taken to achieve success and the measured performance of the sound chambers.

Recognizing a growing need for noise control research and development, Caterpillar has completed a new noise ...
