Acoustic Bundle

Overview

The SAMURAI Acoustic Bundle offers a selection of the most important measurement and analysis methods for acousticians and includes the following SAMURAI options:

 

Short overview of the software options included


Sound Level Meter

SAMURAI-Option Sound level meter

  • Class 1 according to IEC 60561, 60804, 61672
  • A, C and Z frequency weightings simultaneously
  • Fast, Slow and Impulse time weightings
  • Lp, Lmax, Lmin, Leq, Lpeak aller Pegelwerte
  • LE, LAtm1/3/5, Ln
  • 10 Perzentile
  • Evaluation of impulsiveness, low frequency tonality and "Taktmaximal" level
  • Parallel use of up to 5 sound level meter instances per channel; each with up to 61 values in variable time intervals
  • Triggered data storage possible

1/1 & 1/3 Octave Analyser

SAMURAI-Option 1/1 & 1/3 Octaves

  • Calculation with digital filters according to IEC 61260 class 0
  • Real time 1/1 and 1/3 octave analysis
  • 1/3 octaves ranging from 0.04 Hz ... 80 kHz
  • Adjustable 1/3 octave bands (acoustics, vibration and user-defined settings)
  • Averaging modes: linear, fast, slow and exponential
  • Simultaneous display of multiple spectra: current values, max, min and Leq
  • Display and storage of sound level sums
  • Spectra layout options include bar, bar contour or line
  • Up to 5 independent analyser instances per channel
  • Triggered storage possible

Reverberation Time Measurement

SAMURAI-Option Reverberation Time

  • Reverberation time RT60 calculated as T30, T20, T15, EDT
  • Reverberation times from 0.04 s to 60 s
  • Frequency range from 25 Hz to 20 kHz
  • Multi-channel measurements can be done simultaneously or in succession
  • Multiple microphone and speaker positions possible
  • Excitation options: impulse, noise and sine sweep
  • For sine sweep mode: backward integration of the impulse response
  • Display of the specific decay curves with optional manual adjustment of the regression line
  • Zoom functionn
  • Average reverberation time derived from several measurements and measurement positions
  • Evaluation according to ISO 3382-2, BT 16 criteria: noise floor, correlation coefficient, degree of curvature & standard deviation
  • Measurement of structure-borne noise reverberation time using shakers and accelerometers

Requirements

The SAMURAI-Acoustic-Bundle requires a valid SAMURAI-base license.
