Sound level meters and noise dosimeters get damaged in a variety of ways including dosimeter microphone cord stretching, scratched microphones, and dropped meters. However, a true noise survey should be done using a suitable calibrated Integrating sound level meter. The CR308 sound level meter starts measuring noise levels as soon as it is switched on. 4. This low cost noise meter has been designed for simple noise surveys and sound level checks. If you are measuring noise in line with the US OSHA or European Noise at Work regulations (i.e. The bar at the top of the display shows the current sound level and how it fits within the range of the meter. Building acoustics measurements require an omnidirectional sound source, a power amplifier, and a tapping machine. If you need to be able to pick the meter up and make a quick measurement, without fiddling with buttons first, then this is likely to be the best choice. A noise dosimeter is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the Occupational Safety and Health (OSHA) 29 CFR 1910.95. The most advanced 2-channel instruments can even measure one channel of sound and one channel of vibration. This means that rework is extremely costly and must be avoided. Scheduling regular sound level meter calibration as part of … Noise dosimeters measure and store sound pressure levels (SPL) and, by integrating these measurements over time, provide a cumulative noise-exposure reading for a given period of time, such as an 8-hour workday. If you have any doubts please email us for advice. The Noise Level Meter is an instrument used to measure the ambient sound level,such as sound level around factories, workshops, schools, residential, offices, road, audio etc.It also can be appropriate for noise … The meter also provides the Maximum and Minimum readings for whichever weightings are selected.
