Enviro Noise Partner
Measure environmental noise
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
Get your environmental noise measurement job done with the Enviro Noise Partner app for your B&K 2245 and HBK 2255 sound level meter.
Enviro Noise Partner for your B&K 2245 and HBK 2255 sound level meter is a complete solution for environmental noise surveys. Use the app to remotely control your noise measurements from a safe distance, to minimize your impact on the sound field. Investigate the tonal characteristics of noise with real-time 1/1 or 1/3 octave band frequency analysis. Examine how sound levels change over time with Enviro Noise Partner’s powerful logging profile views, and isolate sections of your measurements using markers. Document your work with photo, video, text and voice note annotations embedded directly into the measurement data.
