VA-Lab BASIC
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
