Acoustics - Vibrations
AV-11
The HD2110L is
a precision integrating
portable sound level
meter, with mul-
tiparametric
data logging capability,
providing both spectral
and statistical
analysis. The instrument has been designed in order to offer
high-performance
analysis of acoustic phenomena, with particular regard to
legislation on environ-
mental noise. Attention has been paid to the possibility to
update the instrument
in order to comply with the technical standards evolution.
The HD2110L can be
integrated with additional options to extend its application
range when required;
the fi rmware can be updated directly by the user by means
of the Noise Studio
program provided with the instrument.
Technical regulations:
