Nova Integrating
Sound Level Meter

Standard Meter

The Pulsar Model 44 Nova Integrating Sound Level Meter includes all the noise measurement parameters needed for an occupational noise survey. All you need to add is a Calibrator to check the meter's function before starting a measurement session.

The rest of the options are just dependent on how you want to use the meter (download to computer, etc.) or whether you have other applications that you would like to use the meter for, such as environmental noise surveys.


Type 1 or Type 2

For most occupational noise regulations, including OSHA, MSHA and ACGIH, you should use a meter that meets the ANSI S1.4 regulations to at least Type 2.

The EU Noise at Work Regulations demand the use of a meter that meets IEC 61672 to Class 2 or better meter.

The Model 44 meets all these requirements perfectly.

If you have other noise measurement applications, such as certain environmental assessments, you might need the Type 1 Model 43. This can also be used for occupational noise as it exceeds the requirements (Type 1 is more accurate than Type 2).

Sound Level Calibrator

Most noise measurement regulations state that you should use a Sound Level Calibrator before and after each measurement session. This is a hand-held device that fits over the meter's microphone and emits a precise tone, which the meter uses to check that it is measuring accurately. If any small adjustments are needed the meter does this automatically.

We recommend the use of a Calibrator for any measurements that are to be used for legal purposes or in the protection of a worker's hearing.



A windshield is used to reduce the effect of wind on the microphone capsule. It is recommended for occupational noise measurements as it protects the microphone against being accidentally knocked against hard surfaces. It is essential for making outdoor measurements on all but the calmest of days.


Data Logging Option

With the data logging option fitted the meter stores all the measurements, including the Time History, which gives a detailed graph of the sound level over time. This is particularly useful if you intend leaving the meter unattended in a workshop for example, to get some long term noise measurements.

Once downloaded to the Analyzer software, you can link measurements to workers and produce reports. Although this can be done by hand without the data logging option, record keeping on the computer is usually much more convenient. Special Noise at Work reports are included with the software.

You can read more about this option on the Software page.
