2260 Observer sound level meters from Noise and Vibration Measurement Systems are state-of-the-art instruments designed to provide accurate community and workplace noise assessments. These sound level meters comply with sound level meter standards such as IEC 61672 as well as the previous IEC standards (60651 and 60804) and the latest ANSI standards.
All broadband parameters and statistical values are measured in parallel with all parameters available. Operators choose what is to be examined now or later.
Other features of 2260 Observer sound level meters include:
- Real-time analysis in 1/1 or 1.3 octave bands (carried out simultaneously)
- Broadband and spectral data can all be logged to obtain a time history profile for later analysis
- Optional measurements of reverberation time using impulsive noise or built-in generator and sound source
- Can be upgraded to include the full range of advanced applications from the 2260 Investigator portfolio (e.g. sound intensity, two-channel building acoustics, FFT analysis)
