Remote construction noise monitoring.
The Journal of the Acoustical Society of America, 2010Los Angeles was constructing an underground 12 ft in diameter sewage tunnel stretching 25 km. The project includes nine construction access shafts where tunnel boring machines, muck trains, and materials were lowered into the ground. The excavated tunnel material was transported from the tunnel head to the access shafts by muck train, removed by a ...

Rocket-Noise Monitoring System
The Journal of the Acoustical Society of America, 1966This report describes the performance of a system designed to meet the specific requirements of monitoring rocket noise in communities located miles from the test site. The pole-mounted remote stations were designed to transmit their signal via normal telephone voice channel.

Aircraft Noise Monitoring at Airports
Aircraft Engineering and Aerospace Technology, 1980Aircraft noise nuisance, particularly in the vicinity of airports, makes it necessary to monitor aircraft noise continuously. As with all kinds of other monitoring installations used in environmental protection, aircraft noise monitoring also contributes to the reporting, investigation and prevention of nuisance and damage. Specific tasks are generated

Development of Reactor Noise Monitor
Journal of Nuclear Science and Technology, 1979A reactor noise monitor has been developed to provide a tool that serves the real time routine function of detecting anomalous states of operation in power reactors. In this monitor, RMS (root mean square) values and average frequencies of noise signals are calculated on a real time basis.

Airport noise monitoring ‐ a review
Aircraft Engineering and Aerospace Technology, 1997Suggests that before measurement of noise can be implemented all “non‐aircraft noises” must be eliminated. Sets out various approaches to the problem of airport noise: the acoustic companies’ approach; the systems companies’ approach; systems costs; flight identification and correlation; and noise monitoring.
