HD2010 Precision Sound Level Meter.
HD2010 Sound Level Meter 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 Sound Level Meter 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.

Precision Sound Level Meter

Model  Description 
HD2010  HD2010 Precision Sound Level Meter.

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.
