SoundPro SE & DL Sound Level Meters and RTAs

Advanced Handheld Acoustic Measurement Systems

All-in-one instruments Two virtual integrating sound level meters run simultaneously One sound level meter is switchable between broadband and RTA mode Concurrent C and A-weighted measurements Easy operation and convenient features that meet your applications Time history datalogging with 1 second to 60 minute intervals (model dependent) Predefined setup profiles and unlimited user-defined setup profiles Back-erase up to 20 seconds to remove test anomalies from results Models with reverberation measurement available Rugged, lightweight, and ergonomically designed Only 1.2 pounds (0.5 kg) Flexible communication capabilities Quickly upload data via high-speed USB Secure data card slot for flexible data storage Integrated with Detection Management Software (DMS) Software Compliant with ANSI and IEC standards

The SoundPro® SE & DL Sound Level Meters/Real-time Frequency Analyzers (RTAs) and Detection Management Software make advanced noise analyses easy. With one mouse click, select from a library of pre-defined or user-defined application profiles. Two virtual sound level meters measure noise in accordance with dual thresholds common in many occupational noise regulations. The RTA allows selection of simultaneous broadband or RTA measurement modes for one of the virtual sound level meters. RTA mode provides real-time display and storage of the entire set of 1/1 or 1/3 octave spectra simultaneously. Rapidly transfer data to a PC with high-speed USB cable or store data on a non-proprietary removable SD memory card.

• Occupational noise evaluations including:
• The recently amended U.S.A. Federal Railroad Administration (FRA) standard for noise exposure in locomotive cab
• The ANSI A10.46-2007 standard for construction and demolition worker noise exposure


• Hearing protector selection measurements



• Environmental noise assessments



• Noise ordinance enforcement and legal metrology



• General sound and frequency analysis measurements

Detection Management Software (DMS)
Detection Management Software (DMS) makes it easy to retrieve, manipulate, report, share and store data collected by 3M/Quest datalogging instruments for noise dosimetry, sound measurements, heat stress assessment, indoor air quality evaluation and environmental monitoring. Advanced DMS Software is similar in functionality to QuestSuite Pro II Software, but includes many new features:

• Quick, easy navigation
• Data sorting into sessions/studies
• Fast report generation
• Click, drag, and drop report/graph customization
• Support for Acrobat PDF
• Advanced reporting and analysis
