Nova Octave Band Sound Level Meter - Models 45 and 46

Nova Octave Band Sound Level Meter


The Nova models 45 and 46, are integrating sound level meters with real-time octave band filters. This is a data logging meter that comes complete with the Pulsar Analyzer Plus software.

These models come with all the Nova options fitted - there is nothing to add. Data logging, octave band filters, environmental Ln parameters, automatic timers, everything is already in there.


Sound Level Meter Standards

  • ANSI S1.4 Type 1 or Type 2
  • IEC 61672 Class 1 or Class 2
  • IEC 60651, IEC 60804 Type 1 or Type 2
  • ANSI S1.11 and IEC 61260 for Octave Band Filters

The Nova range of sound level meters have been designed to be as quick and easy to use as they can be. Rather than wasting time setting the meter up before making measurements or, even worse, making the wrong measurements, the Nova measures all parameters simultaneously. To keep things clear it only displays the parameters that you need to see. On the main display for occupational noise measurements you will see the average sound level and Peak, which are the main parameters. If you realize later that you needed the LCeq (this is quite common for occupational noise) or even the full octave band spectrum then it is all there too.

This meter also has a single measurement span from 20 to 140 dB. With older technology meters you have to select the measurement range first, but not with the Nova. This really reduces the incidence of over-range and under-range measurements, particularly for octave band measurements.

Occupational Noise and Hearing Protection

As preferred for most occupational noise regulations, the Nova model 46 is an integrating sound level meter and meets the standards to Type 2. You can also use the Model 45, which meets Type 1. This will cost more but can be useful if you have other noise measurement regulations to meet that require the higher grade.

As this meter is fitted with real-time octave band filters, it can be used to estimate the sound level at the ear when wearing different hearing protection. There are three standard methods, with the Octave Band method being the most detailed and the most accurate, particularly when tonal noise is present.

Hearing Protector Assessment

The software includes a database of hearing protectors. It takes the octave band measurement and calculates the resultant level at the ear with each protector, using the standard octave band method. All the calculations are done for you, presenting you with a report showing a list of all protectors in the database, or a detailed report for your selected protector.
