CEL633B Environmental Sound Level Meter with Octaves

CEL633B Sound Level Meter

Applications

The CEL633B is a Sound Level Meter that includes the usual environmental noise measurement parameters along with real-time octave band filters for tonal noise assessments and hearing protector analysis.

  • Environmental noise measurements
  • Noise Ordinance and Community noise assessments
  • Noise in mixed residential and industrial areas
  • Occupational noise measurements
  • Noise source identification

Due to the nature of environmental noise surveys (both the acoustic nature and the political nature) we recommend the use of a Type 1 sound level meter.

This version of the CEL633 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 Type 2 as being adequate, all versions of the CEL633B are suitable. If you need to measure both environmental and occupational noise then this meter will do both.

Short Term Environmental and Community Noise Surveys

The CEL633B 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)
  • Octave Bands for tonal noise analysis

Noise Source Identification

Unattended noise measurement is convenient but causes problems when the time comes to identify the source of the noise. Was it a car, a strong gust of wind blowing the leaves or somebody shouting. The CEL633B can record the audio so that you can listen to the interesting bits, enabling you to make a positive identification of the noise source.

Please visit the Voice Notes and Audio Recording page for more details.

 

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:

  • Lavg and Leq (average sound level) for TWA calculations
  • Peak for loud banging noise
  • "A" and "C" weighting for hearing protector evaluation
  • Octave band measurement for detailed hearing protector evaluation
