HD 2010 UC/A – Integrating Sound Level Meter – Frequency Analyzer

HD2010UC/A is a portable integrating sound level meter, with multiparametric
data logging capability. It is suitable for statistical and spectral analyses, the
instrument has been designed by combining maximum fl exibility, cost effectiveness
and usability. Attention has been paid to the possibility to update the
instrument in order to comply with the standards evolution concerning acoustics.
In order to adapt to the current and future users needs, it is possible to add
options to the HD2010UC/A so to extend its applications; the user can update
the fi rmware directly by means of the noise studio software supplied with the
instrument.

Product Description

HD2010UC/A is a portable integrating sound level meter, with multiparametric
data logging capability. It is suitable for statistical and spectral analyses, the
instrument has been designed by combining maximum fl exibility, cost effectiveness
and usability. Attention has been paid to the possibility to update the
instrument in order to comply with the standards evolution concerning acoustics.
In order to adapt to the current and future users needs, it is possible to add
options to the HD2010UC/A so to extend its applications; the user can update
the fi rmware directly by means of the noise studio software supplied with the
instrument.
Technical regulations:
• Class 1 or 2 sound level meter according to IEC 61672-1-2002 (Type Approval
Certifi cate I.N.RI.M. No. 07-0124-02), IEC 60651 and IEC 60804.
• Class 1 octave and third octave fi lters according to IEC 61260.
Applications:
• Assessment of the environmental noise level,
• Noise monitoring, capture and analysis of sound events,
• Octave and optional third octave bands spectrum analysis from 25 Hz to 12.5
kHz,
• Statistical analysis with the calculation of 3 percentile levels and full statistical
analysis,
• Identifi cation of impulsive noise,
• Measurements in workplaces,
• Selection of personal protective equipment (SNR, HML and OBM methods),
• Sound insulation and reclamation,
• Production quality control,
• Measurement of machine noise,
• Optional architectural and building acoustics measurements.

By using the HD2010UC/A, you can log the time profi le of 4 simultaneous
parameters freely selecting time or frequency weightings. The possibility to display,
store and even print the multi-parameter analysis of the sound level allows
the sound level meter to work as a sound level logger capable of storing for
more than 23 hours. For sound level monitoring, you can store 3 programmable
parameters and the average spectrum at intervals of 1 second to 1 hour. In this
recording mode, you can store the sound level (3 parameters + spectra) at intervals
of 1 minute for over 23 days using the supplied memory (4 MB expandable
to 8 MB). An advanced acquisition mode allows storing report sequences with
dedicated parameters, average spectra and full statistical analysis, as well as
sound level profi les. Moreover, a versatile trigger function can identify the sound
events and record their analysis with 5 dedicated parameters, average spectrum
and statistical analysis.
The spectrum analysis is carried out simultaneously with the profi le logging in
real time by octave bands and optionally by third octave bands. The sound level
meter calculates the sound signal spectrum twice a second and can integrate it
linearly for up to 99 hours. The average spectrum is displayed together with an
A, C or Z -weighted wideband level.
As a statistical analyzer, the HD2010UC/A samples the sound signal 8 times per
second with A-weighting and FAST time constant and analyzes it statistically in
0.5 dB classes. Up to 4 percentile levels, selectable between L1 and L99, can be
programmed. It can be decided to sample the following: LFp, Leq and Lpk with A,
C and Z -weightings (only C and Z for Lpk)..
Additional functions as advanced sound analyser are available in the basic
version:
• Statistical analysis in graphic form both as probability distribution and as
cumulative distribution
• Trigger functions for sound events capture with threshold level and event
duration fi lter
• Record of measuring REPORTS with programmable intervals from 1 s to
1 hour with a customizable set of 5 parameters, complete statistical analysis
and frequency multi-spectra
• Acquisition of noise events with the possibility to set the maximum temporal
resolution for event recording and a lower resolution for background recording.
