What do you need to measure for the Noise at Work Regulations?

FAQ, Noise at Work, Questions No Responses »
Jul 212011

When making measurements to estimate the noise exposure of a person at work, you need to ascertain the equivalent continuous A-weighted sound pressure level (LAeq) that represents the noise the person is exposed to during the working day. You also need to ascertain the maximum C-weighted peak sound pressure level or levels to which the person is exposed.

The action levels described in the regulations are given as daily (LEP,d) or weekly (LEP,w) exposure values along with peak sound pressure levels, all in dB.

A sound level meter cannot measure LEP,d or LEP,w directly as these are calculated from two other parameters which are recorded during the measurement. These are:

  • The equivalent continuous A-weighted sound pressure level in decibels that represents the sound the person is exposed to during the working day
  • This is commonly known as the Leq and may be shown as LAeq or LAeq,t
  • The duration over which the Leq is measured Continue reading »

    Noise in the refuse and recycling sector - time for a reality check!

    May 022011

    David Wilford of No Going Back Productions, a specialist in noise measurement for waste collection and recycling services, discusses noise risks in the refuse and recycling sector

    An efficient and effective refuse and recycling service plays a pivotal role in local communities and the surrounding environment. However, as recycling initiatives have developed, they have brought with them dangerous levels of noise that those working in the sector are exposed to on a daily basis; from traffic and vehicle machinery, to the actual disposal of refuse and recycling. This combination of noise, results in high exposure to noise levels that, without the correct hearing protection, can lead to permanent hearing damage. Continue reading »

    If you are using your noise measurement instrument to meet any Standards, Regulations or Guidelines  it is essential that your equipment is measuring accurately.

    If you are working to the Noise at Work Regulations 2005, or any ISO or BS EN standard that requires the use of noise measurement equipment, the standards to which the equipment must comply will be clearly stated. If you are going to continue to use your noise measurement instruments it is vital that they continue to meet these same standards. Continue reading »

    Noise measurement in the refuse and recycling sector - the shattering reality!

    Feb 072011

    The ability for a local authority to provide an efficient and effective refuse and recycling service is pivotal for both residents and the upkeep of the surrounding environment.  However with the increased noise levels that new recycling initiatives generate it is imperative that the welfare of operatives working in this sector is looked after rigorously.  David Wilford of No Going Back Productions, a specialist in noise measurement for waste collection and recycling services, discusses noise risks in the refuse and recycling sector.

    Refuse and recycling operatives are subjected to a vast amount of noise, ranging from that generated from traffic and vehicle machinery, to the actual disposal of refuse and recycling; this combination of noise results in high exposure to noise levels that, without the correct hearing protection, can lead to permanent hearing damage.  For example, when glass impacts on glass, i.e. when a plastic box or wheeled bin is emptied, extremely high levels of noise are emitted.  Peak levels above 140 dB(C) are common and it is possible during a typical shift for a loader to be frequently exposed to peaks above 137 dB(C).

    Sep 152010

    Specialist noise measurement equipment manufacturer Cirrus Research was proud to be part of the Safety and Health Expo 2010 where it showcased its new generations of Optimus Sound Level Meters including the Optimus Green, the newest member of the Optimus family.

    Cirrus held a competition at the May event with the chance to win one of the cutting edge Optimus Sound Level Meters and Tony Bailey of construction group Galliford Try was the lucky winner.

    The news Optimus range of sound measurement is easy to use, flexible and upgradeable in a smart design and includes up-to-the-minute technology. The new Optimus Green strengthens the range of Optimus sound level meters and has been created to combine the existing features from the Optimus range with the latest technological innovation and added functionality that is necessary for environmental noise to be accurately measured.

    This makes it ideal for use in environmental, occupational and industrial environments making it the most advanced Sound Level Meter yet, combining the highest level of performance with simplicity of use.

    Tony Bailey, HS&E Advisor, Galliford Try said: “I was very pleased to discover I had won the Optimus Sound Level Meter as I had spent the duration of the event obtaining information on the different sound meters currently available. It is important for me to assess occupational noise levels and therefore be sure our operatives are wearing the correct ear protection for the activities they carry and be able to advise them on how they can eliminate work related hearing loss.”
