The CEL633 is a Sound Level Meter that includes the usual environmental noise measurement parameters and with options for real-time 1/3 octave band filters for tonal noise assessments. It also has a detailed Time History store and automatic measurement timers.
Environmental noise measurements
Noise Ordinance and Community noise assessments
Noise in mixed residential and industrial areas - BS4142
Occupational noise measurements
Due to the nature of environmental noise surveys (both the acoustic nature and the political nature) we recommend the use of a Class 1 sound level meter.
The version of the CEL630 series of meters includes all the Environmental noise parameters along with a detailed time history store and automatic timers, making it ideal for both short term and longer term assessments.
As most occupational noise regulations accept Class 2 as being adequate, all versions of the CEL633 are suitable for that application too. If you need to measure both environmental and occupational noise then this meter will do both.
CEL633 Sound Level Meter
Short Term Environmental and Community Noise Surveys
The CEL633 sound level meter measures the noise parameters that are needed by most regulations:
Periodic A-weighted Leq (the average sound level)
Ln Percentiles (the statistical values such as L10 and L90)
1/3 Octave Band option for tonal noise analysis
Long Term Environmental Noise Surveys
The addition of a detailed time history store allows for post processing and graphing the noise levels down to a resolution of 1 second, and the automatic timers make it easy to run repeating measurements (for example repeating 5 minute measurements in addition to the 1 second Time History).
The sound level meter can by mounted on a standard camera tripod, but if it is to be left unattended in poor weather conditions you will also need the weather protection offered by the Outdoor Kit.
Occupational Noise
The CEL633 is also suitable for the measurement of noise in the workplace:
Leq (average sound level) for LEP,d calculations
Peak for loud banging noise
"A" and "C" weighting for hearing protector evaluation
Octave band option for detailed hearing protector evaluation
The sound level meter alone or as part of a Kit, which includes Meter, Calibrator and Carrying Case.
