VA Lab Software Overview

VA-Lab is acoustical measurement software which has module designed according to ISO standard requirements, such as Sound Power, Sound Insulation, and Impedance Measurements.

The VA-Lab function modules include:

  • BASIC: FFT based signal analysis for vibration and acoustics

  • ENV: Sound pressure level and environment noise measurements

  • IMP: Two and four microphone methods for absorption and TL measurements in Impedance tube according to ISO10534

  • SI: Sound intensity measurements

  • REV: Reverberation time measurements according to ISO3382   

  • TL: Sound Insulation measurements for building material according to ISO 140.

  • POWER: Sound Power Measurements according to ISO3745.

  • AUDIO: Audio testing by using stepped sweeping, frequency response and THD are tested at one time.

Main features of VA-Lab BASIC:

  • FFT Analysis: general signal analysis including FFT,CPS, Transfer Function, Coherence, Auto Correction, Cross Correction, Cepstrum, etc. Data can be captured and saved in real-time mode

  • 1/n Octave: general 1/n octave analysis for sound and vibration signals, n=1,3,6,9,12, 24

  • Calibration: user selection of sound or vibration calibration.  

  • Signal Generator: sine, square, triangle, sawtooth wave, white noise, pink noise, frequency sweep, multi-tone, tone burst, wavefile, etc.

  • Record: Wave file or time series signal record and play back
