SOUNDADVISORTM OPTIONS OCTAVE BAND ANALYSIS 831C-OB3 In many applications, it is important to acquire both the broadband level and spectral content of noise data. With spectral information, the source and content of the measured level can be better understood. Constant percentage bandwidth filters (1/1 or 1/3 octave) best approximate human perception of sound. Option 831C-OB3 firmware enables simultaneous real-time measurement of 1/1 and 1/3 octave Leq, Lmax, Lmin along with all the ANY LEVEL™ broadband parameters. Option 831C-OB3 is compliant with IEC 61260:2014 Class 1 and ANSI S1.11-2014...

MEASUREMENT HISTORY 831C-ELA While Time Histories are typically logged at one sample per second, longer- term averages are often useful to see trends, e.g., 10 minute or hourly averages. 831C-ELA firmware enables Measurement History (MH) and logs these parameters similar to Time History (TH) over a longer interval time. MH and TH can run together simultaneously or independently. Data for each measurement or location is saved in a unique MH record and may include the Leq, Lmax, Lmin, SPL, and statistical distribution of the SPL (Ln). A complete set of MH records then can be stored in a...

MEASURED SOUND RECORDING 831C-SR Measuring sound levels is a well-accepted way to objectively quantify the noise radiated by a product in an environmental survey. Rather than rely simply on the objective data, why not record a sample of the sound to truly determine the source of the noise? CELLULAR COMMUNICATION 831C-SW We understand how beneficial it can be to have access to your noise monitor at any time of the day. Due to the remoteness or need to setup contracts and get permits, connecting a noise monitor to a wired network or main power just isn’t feasible. The 831C-SR option enables...

SOFTWARE SOLUTIONS The Model 831C has numerous on-board capabilities, yet often further processing, visualization, or reporting needs exist. For this purpose the Model 831C can be used as a portable instrument and retrieve the data, work as a data acquisition front-end, or in combination with other products. G4 LD UTILITY The G4 LD Utility program is easy-to-use Windows ® software for the Model 831C providing configuration set-up, data download, and remote access. Measurement set-ups can be stored on the PC for use on one or more Model 831C Sound Level Meters. Data can be downloaded onto a...
