The Nova Integrating sound level meter meets the very strict requirements of the ANSI S1.4 and ANSI S1.43 standards to Type 1 or Type 2, as well as the IEC 61672 sound level meter standard to Class 1 or Class 2, making it suitable for most noise measurement regulations.
If you are following any particular regulations and you are unsure then please contact NoiseMeters for advice. We can tell you whether the meter is suitable or not, and guide you to the most cost effective option if not.
The Nova Integrating Sound Level Meter meets all the requirements of the OSHA, ACGIH and MSHA regulations along with most others around the world, such as the EU noise at work regulations.
Type 2 Integrating Sound Level Meter
As these regulations demand the use of a meter that meets the regulations to Type 2 or higher, so you can use the lower cost Nova Model 44. You can also use the higher grade Model 43 meter, especially if you have any other applications that demand the use of the higher grade Type 1 meter.
Most regulations and guidelines also state that you should use a Calibrator before and after making occupational noise measurements.
The Nova measures the "A" and "C" weighted sound level (LAeq and LCeq) simultaneously, making it ideal for assessing the suitability of hearing protectors using the standard HML method. The meter even provides you with the C-A figure, making the process a little easier.
Most environmental noise regulations will require the use of a Type 1 integrating sound level meter, but Type 2 is also adequate for some. Check your regulations or give us a call if you are unsure.
As well as the standard occupational noise measurements, the Nova has optional Environmental Parameters (periodic Ln - L10, L90, etc.) and automatic timers. Add these options to the Nova and you have the perfect environmental noise meter.
The Nova Models 45 and 46 have the environmental options fitted.
With its ability to measure occupational noise (hearing protection) and environmental noise (boundary noise checks and other construction noise bothering the local community) the Nova Model 43 is ideal as a multi-purpose device.
The Nova Models 43 and 44 are not fitted with Octave Band Filters - although they can be added at a later date should you suddenly realise you do need them.
For octave band analysis, please see the Pulsar Nova Models 45 and 46 Octave Band Sound Level Meter.
