The SoundAdvisor Model 831C Sound Level
Meter is designed to
make noise
measurement easy.
Due to its color display, connectivity, extensive
software features and small form factor the SoundAdvisor is an ideal
choice for handheld operation. Attended measurements are simplified,
with the ability to control and monitor data via any PC or mobile
device with a standard web interface.
Connectivity
Is Key – Cellular, WiFi, and wired networking are all
available to you when using the SoundAdvisor. The meter can even serve
as its own WiFi hotspot.
Many
Platforms, Same Controls – Whether you are setting up a
test on the meter, checking in remotely from your laptop, or receiving
an alert to your smartphone, you’ll be working with the same interface
and menus across all platforms

NEW
4G Solar Panel Noise
Monitoring System NMS044
|
|
|
Larson Davis has created a new standard for
portable noise monitors by
making the SoundAdvisor
Kit Model NMS044 completely wireless with
solar charging and 4G wireless while keeping it truly portable.
Even
in cloudy
days without AC power,
NMS044 is able to keep running forever, thanks to the low power
consumption
of SoundAdvisor 831C, and the optimized solar panel and battery design.
Avoid
Trips To the Field
– Data will be pushed to Dropbox or secured FTP site automatically. You can spend time in the office, rather
than
travelling to reach remote locations
Instant Alerts –
Receive immediate notification of noise events and use
the recorded sound files to evaluate the cause.

831C measures the decays and then computes the reverberation time according
to ISO 3382-2 or ASTM 2235-04 standards.
When using the Interrupted Noise
method, the 831C not only triggers the data acquisition, but its built-in Noise
Generator can be used to drive the omni-directional sound source.
Recent trends
show that the Integrated Impulse method is gaining popularity and 831C handles
the acquisition of the decays and the subsequent T20 or T30 calculations completely
and with ease.
