Abstract

Describes some recent research and development in acoustical standards calibration at NRC. Topics included are: instrumentation and apparatus for precise reciprocity and comparison methods of calibration of condenser microphones. Also, a three-port two microphone cavity technique for the overall calibration of sound level meters is discussed together with various methods of verification of acoustical calibrators
