SV 307
Noise Monitoring Station
All in One
The SV 307 is a new Noise Monitoring Station
dedicated for permanent noise monitoring.
The compact waterproof housing of the SV 307
integrates: a class 1 data logging sound level meter,
patented acoustic system check, GPS module and a
wireless 3G modem.
Wireless communication, external powering and
control of the SV 307 is managed by the SvanNET
cloud service. SvanNET is an on-line solution with
a responsive design that is available on various
devices such as smartphones, tablets and any
standard PC using a web browser.
What's inside?
The SV 307 is an integrated Noise Monitoring
Station which means that the sound level meter
has been integrated with a 3G modem and outdoor
enclosure. The waterproof power supply is also
provided for continuous operation in the field. Each
SV 307 has its factory calibration certificate and
36-months warranty card.
The key part of the class 1 kit is the new MEMS
microphone with a lifetime warranty.
Key issues of noise monitoring
Fundamental issues of the environmental noise monitoring application are:
measured indicators, powering, remote system check, remote communi-
cation and alarms.
What do we measure?
Use of 2 logging steps
Environmental noise measurements often use longer term ISO 1996-1 indicators
such as Lday and Lnight for compliance reporting and short term LEQ for
monitoring and alarm notification, e.g. based on 5 min results. With two
separate logging steps the SV 307 is capable of providing the required results
for both requirements simultaneously.
SV 307 User Guide
The SV 307 is capable of l The SV 307 is capable of logging sum-
mary results (SR) and spectral data
with interval steps down to 1 second.
Also time history results (TH) down
to 100 milliseconds.
Summary results (SR) include LEQ,
PEAK, MAX, MIN with Slow, Fast, Im-
pulse time constants simultaneously.
Additionally SV 307 stores two rolling
LEQ, ten LN statistics and GPS coordi-
nates. If enabled, the summary results
also contain weather data results
such as wind speed and direction or
rainfall.
TH results offer fast saving of PEAK,
MAX, MIN, LEQ and 2 RUNNING LEQs.
If used, the 1/1 or 1/3 octave spectral
results are recorded in both SR and TH
results simultaneously.
