| Abstract |
An aerial monitoring system was developed to measure the noise produced in communities. The system consists of a tethered helium filled balloon which lifts an F.M. telemetry sound measuring system to altitudes of 300 m. A ground station receiving the telemetry signal demodulates it so that the noise at the microphone can be heard and analyzed on the ground. Measurements were taken at 10 sites in Boulder, Colorado, during the winter and summer seasons to evaluate the system's performance and to develop operational procedures. The test program revealed that the City of Boulder has on the average the same noise levels during the winter and summer seasons. Operational procedures for use of the system by communities were developed. |
