Sound pressure level display

Quasi analog and digital display

Simulated Display View

Display the current sound pressure level (SPL) based on the selected response time and filter weighting. The amplitude of measuring sound pressure level will be displayed simultaneously in the form of horizontal bars and numbers, with the numbers displayed below the bars. If the measured value is higher than the minimum value of the selected measurement range, a bar will appear.

1/1octave

Bar chart display

Bandwidth Bar Chart View

The screen displays 13 columnar bars, including data within a specific bandwidth of 11 1/1 octave band filters and bandwidth sound pressure level data of 2 measurement channels. If the measured value is higher than the minimum value of the selected measurement range, a bar will appear.

1/3octave

Bar chart display

Bandwidth Bar Chart View

Optional features andScalability

Quest SoundProOutdoor detection system(SP-OMS)

The SoundPro outdoor detection system helps protect instruments from wind, rain, snow, chemicals, particulate matter, animals, damage, and theft, and can also extend battery life for up to a week of continuous monitoring (with the option of a second battery for two weeks). In addition to storing instruments and battery packs, the weatherproof outer box also has space for accessories and system components. The exposed components are made of stainless steel, ABS, and engineering polymers. The OMS kit includes all necessary support rods, windproof balls, cables, battery packs, and adapters required for the use of SoundPro SE and DL instruments. Customers can also place the outer box on a fixed object using padlocks and cables.
