Octave Frequency Analysis App - BZ-7228

Analyse, in real-time, the 1/1- and 1/3-octave filter bands with a dynamic range in excess of 135 dB, from the noise floor to 140 dB, the maximum measurable level on your Type 2250 and Type 2270 sound level meter.

This software module allows real-time frequency measurements in 1/1- and 1/3-octave bands, making it a simple matter to, for example, select suitable hearing protection, qualify noise from heat and ventilation systems and assess tonality.

Spectral data can be measured for five different parameters: Leq, LFmax, LFmin, LSmax and LSmin. You can select which frequency weighting (A, C or Z) during the measurement setup. In addition, instantaneous values are available for display.

With a single, wide dynamic range, combined with simultaneous measurement of RMS and peak levels with different frequency and time weightings, you can gather all information in one go.

The colour display provides spectral data graphically, clearly providing a wealth of data and measurement quality information in an easy-to-navigate way. Two spectra can be superimposed on the display.

Results from data analysis can be used in a variety of ways, including selection of hearing protection and product quality control.
