Octave Band Filters and automatic hearing protection prescription

This version of the Nova has real time 1:1 octave bands included as standard meaning that it measures all the noise frequency bands at the same time - parallel filters. The most common use for this is for the correct selection of hearing protection (hearing defenders). As octave band filters allow the frequency content of noise to be measured and analysed it is possible to prescribe hearing PPE that attenuates noise at the right frequencies. 

Our outstanding Pulsar ‘AnalyzerPlus’ reporting software (supplied as standard), comes with a comprehensive list of modern hearing PPE. The software takes the measured octave band frequency data and calculates the assumed level of hearing protection at the ear allowing the user to prescribe the correct level of protection.

Easy to use and effortless reporting

Our license-free AnalyzerPlus software, also  allows you to store your measurements in the large internal memory and then effortlessly transform your measurements into a variety of reports at the touch of a button.
