Reference Sound Source Norsonic Nor278

Reference sound source for sound power measurements.

• The rugged and compact design makes it well suited for both laboratory and field use.
• The design ensures a stable and uniform sound power output with unique long-term stability.
• The reference sound source Nor278 is designed to produce a stable and uniform sound power output with unique long-term stability. The high sound power output makes it ideal for sound power measurements in a noisy environment. The rugged, but yet portable and light weight construction is perfect for field us as well a laboratory use. Every effort is made in the design to ensure a uniform frequency response and optimum directional characteristic well inside the requirements in ISO 6926.

Applications:

• Comparison method for determination of sound power of noise sources according to ISO 3741, ISO 3743-1 and ISO 3747.

Features:

• A weighted Sound power output: 94 dB re 1 pW (50 Hz line frequency)
• Sound power 50 Hz – 20 kHz: 94 dB re 1 pW (50 Hz line frequency)
• Fulfils ISO 6926 – 1999 (ANSI S12.5 – 2006) for
• reference sound sources in the extended frequency range 50 Hz – 20 kHz.
• Individual calibrated (accredited calibration optional)
• Long-term stability
• Weight 18 kg (50 Hz) /  24,5 kg (60 Hz)
• Rugged

Accredited Calibration

• Each unit is carefully assembled and individual tested. To enhance the level of quality and traceability of your measurements every unit can optionally be accredited calibrated by the Norsonic Calibration Laboratory in accordance to ISO 6926 – 1999. This service is also offered for periodic re-calibration.
• Norsonic Calibration Laboratory is an accredited laboratory to work in compliance with ISO/IEC 17025 in carrying out calibration of acoustical equipment for measuring noise (sound level meters, microphones, dose meters and
  acoustical calibrators), accelerometers, tapping machines and reference sound sources. The  accreditation is recognized internationally through European and global multilateral agreements in more than 40 countries around the world made through the International Laboratory Accreditation Cooperation – ILAC. Thus the Norwegian Accrediting body has established that Norsonic calibrations are internationally accepted as being carried out in an accredited laboratory.
