Introducing: Larson Davis Debuts Model 831 Handheld Sound
Level Meter/Analyzer for Environmental Noise Analysis
 March
15, 2006, Provo, UT, USA Larson Davis, a PCB Group
Company, has introduced the Model 831, a Class 1 handheld
sound level meter with exceedance-based logging analysis (ELA)
for community noise assessment.
Model 831 features a small, lightweight ergonomic design;
real-time 1/1 and 1/3 octave spectra, and comes standard
with a 120 dB dynamic range. Ten customizable markers are
provided to annotate time history data. The sound level
meter also has audio and voice recording with replay,
supported by up to 2 GB of on-board memory and optional USB
2.0 data stick.
For unattended noise monitoring, its event-based logging
routines process data on-board to provide time/date,
duration, average and max/min sound levels, frequency
spectra, time history records of selected sound levels and
even digital sound recordings for each event. The routines
are specifically designed to save the user time in
downloading and post-processing massive amounts of
unprocessed sampled data.
For optimal digital communication, the
Model 831 provides a
USB 2.0 port to communicate with a PC for instrument control
and downloading data. In addition, using native support for
TCP/IP and built-in USB host port, the 831 can interface
directly with GPRS and Ethernet devices for simple Internet
connectivity. The unit features one-hand operation, and has
an easy-to-read backlit display, whether in direct sunlight
or in a dark factory environment. Plus, when used with a PC,
the USB cable provides instrument power and recharges
batteries, much like an MP3 player.
A full line of accessories is available including software,
sound level calibrators, outdoor microphones systems with
electrostatic actuators, weatherproof enclosures for short
and long-term monitoring and a variety of tripods and
tilt-down poles. All Larson Davis products are accompanied
by full technical support and our guarantee of total
customer satisfaction.
