Sound Level Meters for Occupational, Industrial Hygiene & Noise at Work
Measurements
The most common application for Sound Level Meters is for the measurement of
noise levels to ensure compliance with Occupational or Noise at Work limits.
Across the EU and in many
countries worldwide these regulations require the measurement of Leq and
Peak(C). In particular the EU Physical Agents (Noise) Directive specifies
the exposure limits for employees over an 8 hour day.
Cirrus Research plc has a range of Sound Level Meters that have been
specifically designed to provide these measurements whilst being simple to
use.
Environmental Noise Monitoring
Environmental noise is becoming one of the most important issues in the
field of noise measurement and acoustics. The measurement, recording and
reporting of environmental noise limits has become an essential part of the
work of noise consultants and noise
measurements professionals worldwide.
Cirrus Research plc has a range of noise measurement solutions that are
suitable for environmental noise measurement and monitoring including Sound
Level Meters that can be used either as a handheld instrument or as part of
an outdoor measurement kit.
The CR:800B Data Logging Sound Level Meters are the ideal instruments for
this application, providing a large memory for up to 13 days of continuous
recording of data, simple operation and compatibility with both the
Lightweight and Heavy Duty Outdoor Measurement Kits. | |
