This environmental noise solution for B&K 2245 Sound Level Meter is a complete, focused toolset for measuring and reporting on environmental noise concerns. The sound level meter’s IP55 rating ensures that you can set up and measure where you need to be, without having to worry about exposure to water or dust, for example, at a construction site. Once on-site, the sound level meter app can acquire a wide range of broadband parameters including statistics, provide 1/1- or 1/3-octave band frequency analysis, and conduct logging down to 1 s intervals. These capabilities ensure that you get the right data for your job to do. Additionally, the sound level meter can make high-quality audio recordings to aid in identifying specific incidents.

B&K 2245 is type approved by multiple authorities, including PTB and CEM.

Mobile App

Once the mobile Enviro Noise Partner app is downloaded to your phone from the App Store®, your B&K 2245 can be wirelessly controlled from your phone – you can even control multiple B&K 2245 sound level meters simultaneously. All measurement capabilities are available from the app, with intuitive measurement profile screens that enable you to pinch the graph to zoom or swipe it to move back and forth through time. This makes it very easy to mark events and isolate sounds so that you can, for example, exclude a barking dog from measurement. Measurement audio can be streamed to your phone while measuring, useful in situations where you cannot be physically close to the sound level meter, or to listen for wind-induced noise. Via the app interface, pictures, text and voice notes, and videos can be embedded with the measurements to document your work.

PC App

With the accompanying PC app, all data can be transferred to a PC, wirelessly or with the supplied USB cable. Just like the mobile app, the Enviro Noise Partner PC app is an excellent tool for adding markers for events and isolating sounds for further investigation or exclusion. These tasks are made even easier with the app’s powerful audio playback tools, such as pitch-corrected high-speed playback for reviewing long recordings. Measurements to can exported to customizable Microsoft® Excel® templates for fast, easy and consistent reporting.
