COVER STORY
SAFE AND SOUND
Cirrus Research tells Tomorrow’s Health & Safety why its range of sound level meters blows the competition out of the water when it comes to hearing protection.
Cirrus Research still leads the noise measurement field with its “one product - one price” package that covers all Noise at Work requirements through its Optimus® Red range.
With no hidden costs, the Optimus Red sound level meter can claim to be the industry leading product that covers ALL areas of UK and European Noise at Work legislation; taking away any uncertainties for professionals looking for a Class 2 sound level meter.
“We know that it can be confusing for customers in terms of which product will meet their exact needs. That’s why we have the Optimus Red, so they know it has absolutely everything covered for Noise at Work measurements,” explained Marketing Manager Thomas Shelton.
“Some products on the market offer a basic noise measurement model but then you have to choose add-ons such as a data logging system. We decided to offer ‘one product for one price’ that covers all the Noise at Work requirements, which is our specialism.”
Included in the Optimus Red 162C as standard but on other rival products as “extras” are:
• Data logging of measurements and calibration records
• 1:1 octave filters • Voice Tag audio recording • Single timer • TWA Dose
“When it comes to Noise at Work measurements, we know that the Optimus Red ticks all the boxes on

every legislative level and all our customers like and depend on that certainty,” added Thomas.
It was this level of support and product reliability that helped race engine manufacturers, Ilmor Engineering, protect its employees at their UK manufacturing base.
The company was successful in winning a large contract with the US giant General Motors to design and manufacture a new turbo-charged V6 racing engine, but its managers knew this would impact on noise levels across the company.
The new contract meant additional tools would be installed in the main machine shop. These had the potential to ‘tip’ some of the operators above noise exposure of 80dB(A). A repeat
occupational noise exposure survey was carried out using a Cirrus Research wireless personal noise dosimeter - the doseBadge® - coupled with the Optimus Red.
Accurate measurements and recording of employees’ long-term exposure to noise was tracked, and it was found that there were several points in the day where noise exposure levels were greatly exceeding 80dB(A). After analysing the graphical traces from the doseBadge, they also suspected that the principle reason was due to the increased use of air guns.
A more detailed investigation using a Cirrus Optimus Red sound level meter began and enabled measurements to be taken of the peaks at a range of different frequencies.
The results were relatively similar to those previously recorded but the main difference was significantly more occurrences of the air gun being used per shift. Thanks to the very detailed and accurate information provided by both the doseBadge and the Optimus Red sound level meter, Ilmor Engineering was able to modify its manufacturing processes, taking noise exposure back down to previous levels.
Both the Optimus Red and doseBadge ranges will be on the Cirrus Research stand at the Safety & Health Expo at ExCeL in London, 16th – 18th June, stand P2150.
