APPLICATION FIELD
The generator noise level 9101/HD HD 9102 is a portable, battery-powered sound source, suitable for calibration of sound level meters (portable and laboratory) and acoustic measuring stations. And ‘possible to calibrate directly microphones 1 / 2 "of mechanical dimensions conform to the requirements of IEC 61094-1 ("Measurement Microphones, Part 1: Specifications for Laboratory Standard Microphones") and IEC 61094-4 ("Measurement Microphones. Part 4: Specifications for working Standard Microphones)
TECHNICAL SPECIFICATIONS
The calibrator HD9101 satisfies Class 1 specifications according to the standard IEC 60942-1988 and complies with the requirements of the standard ANSI S1.40-1984.
Advantages of the acoustic soundlevel calibrators HD 9101 / HD 9102 are:
- With the frequency of the sound signal at 1000Hz can perform calibration of sound level meters with any frequency weighting (LIN, A, B, ...), without introducing correction factors.
- The sound pressure level generated is independent of atmospheric pressure is therefore not necessary to correct the value function of atmospheric pressure.
- The calibrator 9101/HD HD 9102 can be conveniently used in both laboratory and field.
- Ease of use allows the use even by unskilled personnel.
