• Description:
  This Bureau of Mines report describes in detail the design and operation of a test apparatus for measuring the sound power levels of drills used by the mining industry. The two major components of the test apparatus are a computer-controlled automated drill test fixture (ADTF) and a 45,000-ft3 reverberation chamber that houses the ADTF. Design specifications and performance capabilities of the ADTF and the reverberation room are given. Initial test results for three types of drills-a pneumatic percussion drill, a hydraulic percussion drill, and a pneumatic rotary drill-are given to illustrate the types of experiments that can be conducted with the test apparatus.
