24/7 Monitoring and Control
More than a handheld device, SoundAdvisor can be configured as a robust noise monitoring terminal with 4G LTE or LAN connectivity for continuous operation. Ideal for airports, racetracks, and industrial sites, it offers remote control, automated calibration checks, and long-term deployment with PCB microphones backed by a 5-year warranty. Minimise site visits and downtime with our expert engineering support for swift calibration and redeployment.
FFT Frequency Analysis
For detailed frequency analysis beyond 1/3 octaves, the Model 831C-FFT offers precise narrow-band filtering through Fast Fourier Transform (FFT). Ideal for machinery analysis, source detection, and fault diagnosis, it provides objective acoustic and vibration measurements directly in the field using the SoundAdvisor Sound Level Meter.
Reverberation Mode
SoundAdvisor 831C-RA simplifies reverberation time analysis for architectural acoustics, calculating T20 and T30 spectra to ISO and ASTM standards. With built-in noise generation and impulse method options, it provides precise data in 1/3 or full octave bands, ready for export to G4 LD Utility or further analysis in DNA.
Comprehensive Data Analysis
SWW-DNA software streamlines environmental noise, worker exposure, and architectural acoustics analysis with interactive graphs, remote network access, and customisable templates, enabling quick, professional reporting with advanced data visualisation and playback features.
Precision You Can Hear, Reliability You Can Trust
The Larson Davis 831 Sound Level Meter is ideal for environmental measurements due to its precision, wide dynamic range, and ability to capture long-term noise data with real-time analysis.
Its rugged design, advanced data logging, and remote monitoring capabilities make it perfect for assessing noise pollution, compliance, and environmental impact studies.
FFT Sound & Vibration Analysis
Fast Fourier Transform (FFT) analysis delivers precise narrow-band filtering for single-channel acoustic and vibration sources, making it ideal for machinery diagnostics, product testing, source identification, tonality assessment, fault detection, and vibration troubleshooting.
With adjustable FFT settings, SoundAdvisor enables targeted spectral analysis of specific acoustic and vibration events, providing objective measurements directly in the field. Supports Standard 1996-2.
The Ultimate Acoustic Analysis Solution
For acoustic consultants looking for a versatile, user-friendly solution, the SoundAdvisor is a valuable investment for both handheld and long-term monitoring. It simplifies complex noise assessments with real-time octave and 1/3 octave band analysis, audio recording with pre and post-trigger settings, and a low noise option compatible with PCB low-noise microphones.
The back erase function enhances data accuracy, while the reverberation mode is perfect for building acoustics analysis.
