Integrating Sound Level Meter - HD2110L 

Portable Analyzer HD2110L is an integrating sound level meter of high precision , it has functions of data-logging and it can make spectrum and statistical analysis.

The instrument has been designed to offer maximum services on acoustic phenomena analysis with particular attention to italian laws on environmental noise. Attention has been given to the possibility to adjust the instrument on legislation’s evolution. Is also possible to add HD2110L options capable to extend applications and the firmware can be updated by user using “ Noise Studio” equipped.


  • Real time spectrum analysis for octave bans from 16Hz to 16 kHz; 
  • Real time spectrum analysis for third/octave bands with two filter banks: from 16Hz to 20kHz and from 14Hz to 18kHz (option HD2110.O1); 
  • Narrow band spectrum analysis (FFT) to 7Hz to 22 kHz with resolution variable from 1.5 Hz to 100 Hz. Capture Leq profile every 1/32s (option HD2110.O6);
  • Statistical analysis with calculation of probability’s distribution in 0.5dB classes and of all percentiles from L1 to L99; 
  • Simultaneous memorization of multiparametric profiles, reportsat programmable intervals and reports associated automatically to acoustic events identified manually or automatically 
  • Measuring of reverberation time by interrupted source method and with impulse response integration method (option HD2110.O4).


  • Noise monitoring with capture function and analysis of acoustic events; 
  • Measure of acoustic pollution according to decree of 16/03/1998; 
  • Identification of tonal components also located at the intersection of bands and third/octave bands;
  • Evaluation of component spectrum audibility byreal-time comparisonwith isophonics ; 
  • Measure in work places and selection of self – protection gear (SNR, HML and OBM methods);
