HD2010 Digital Precision Sound Level Meter |
|
|
HD2010 is an integrating
portable sound level meter performing either spectral or statistical
analysis.
The 80 dB wide dynamic range, optionally upgradeable to 110 dB,
and the simultaneous measurement with different time and frequency
weightings, allow speeding up and simplifying surveys.
Using an HD2010 you can analyze a sound sample programming 3 measuring
parameters with the most complete freedom of choice of temporal or frequency
weightings.
Together with the logging of the 3 parameters, the spectral analysis is
carried out in real time, by octave bands and optionally by third octave
bands.
The HD2010 calculates the spectrum of the sound signal twice a second and
integrates it linearly up to 99 hours.
Spectra are displayed together with an A, C or Z wideband level.

 |
The HD 2010,
with the optional application for the reverberation time measurement,
calculates 32 spectra
a second allowing to measure reverberation times
using either the interruption of the sound source or the impulsive source
techniques.
The analysis is run simultaneously either wideband or
with octave and third octave bandwidths.
The sound decay analysis, with any frequency
weighting,
can be directly carried out with the
sound level meter.
All these data can be automatically
recorded in the wide non-volatile memory
combined
with a numeric marker, containing the recording
number, date and
time.

|
|
The “Data Logger” option allows to log either the
3 programmed parameters twice per second or the
A-weighted sound level with FAST time constant
8 times
per second.
Recordings can be searched in memory and
viewed on the graphic
display using the “Replay”
function, which reproduces the time trend of the
sound trace.
