Cirrus ResearchRevo™ Vibration Meter: Your Ultimate Solution for Hand-Arm Vibration Measurement
Noise FAQs
Which noise measurement brand do you supply?
We work with Cirrus Research (UK) and supply their Optimus+ sound level meters, doseBadge noise dosimeters, CR310 meter and Quantum fixed noise monitors. We also stock an entry-level Type 2 sound level meter.
What is the difference between a sound level meter and a noise dosimeter?
A sound level meter measures noise at a particular point, which is ideal for area surveys and checking machinery. A noise dosimeter, such as the doseBadge, is worn by an employee and records their personal noise exposure over a full shift.
Which standard applies to occupational noise measurement in South Africa?
SANS 10083 sets out how occupational noise exposure is measured and assessed for hearing conservation. Our article on the new Noise at Work regulations explains the latest requirements in more detail.
Can noise be monitored continuously at a site boundary?
Yes. Fixed noise monitors, such as the Cirrus Quantum and the fixed 4-20mA noise monitoring station, record noise levels around the clock and can send data and alerts to the cloud, which suits environmental and boundary monitoring.
Do sound level meters need calibration?
Yes. Sound level meters should be checked with an acoustic calibrator before and after each survey, and they need periodic laboratory calibration. Contact us to arrange calibration for your instrument.
