Measuring Noise at Work
To satisfy many occupational noise measurement regulations,
you need at least a Type 2 Integrating Sound Level
Meter like the CR262, along with a Sound Level Calibrator.
This should be all you need to do to make noise measurements at
each working position, but may not be the end of the assessment
and protection process. Noise assessments should be made by an
adequately trained competent person.

Checking the Calibration
Before starting a new set of measurements you should check
the calibration and operation of the meter using a Calibrator.
- Push the Calibrator firmly onto microphone
- Switch the Calibrator to 94dB
- Press Cal key on meter
The rest is automatic and the meter shows the results of
the calibration. |

Making the Measurements
1. Position the microphone
2. Select a suitable measurement range
3. Press the Start key on the meter
4. Wait for the Leq to settle or measure until a representative
sample of the noise has been obtained
5. Press the Stop key
You should now note the Leq and Peak readings for your Noise
at Work records and reports. |
These notes describe the process to make a single measurement
using the CR262 Integrating Sound Level Meter. Please refer to
the national regulations and guidelines for information on
calculating the worker's daily noise exposure from these measurements. The order codes SC262 and CK262 include a Sound Level Calibrator,
which is needed to satisfy the requirements of most regulations. |
