The Control of Noise at Work Regulations 2005,
require employers to prevent and reduce the risk to
health from exposure to noise.
The requirements include the assessment of the level of noise
employees are exposed to and where necessary to take measures to
reduce their exposure.
It is unfortunately the case that the majority of
occupational noise assessments are inadequate,
because they simply dont meet the minimum
regulatory requirements. Noise assessments must:
Be undertaken using a integrating
sound level meter; which is capable of
measuring A-weighted sound pressure level
(LAeq) and C-weighted peak sound pressure
level and must meet at least Class 2 of BS
EN 61672-1:2003 or Type 2 of BS EN
60804:2001. Sound level metres must be
calibrated each day before and after making
any measurements using an acoustic
calibrator (internal electronic calibration

Our noise risk assessments are prepared to meet the statutory
requirements of the Noise at Work Regulations 2005 and
will in most cases include a digital map which can
be easily updated when new equipment is provided.
