noiseLAB Pro provides three core elements:

  • Noise Analysis
  • Vibration Analysis
  • Human Impact

Noise Analysis

For classical noise analysis, 1/1 to 1/24 octave analysis is provided along with FFT spectrum analysis with resolution from 1 Hz to 100 Hz. Also included is Sound Level (Z, A, B, C weighting) with choice of integration time constant, Impulse, Peak, and statistical analysis, Leq and LE. In addition, noiseLAB also provides low frequency A weighting and Infrasound G weighting.

Vibration Analysis

Vibration analysis is based on accelerometer signals, which with integration provides velocity and displacement in a variety of units, displayed with linear or logarithmic X and Y scales. Both Peak, Peak to Peak, and RMS (with selectable time constant) are available for vibration analysis.

Human Impact

The human impact of noise and vibration is a major new addition to noiseLAB. In addition to the ISO 1996 Tone Analysis, the classic sound quality metrics of harshness, roughness, loudness (stationary and time-varying), sharpness and fluctuation strength are also provided.

As a leader in psychoacoustic research, the tone analysis method (ISO 1996 Annex 3) was developed by DELTA and is now supplemented by two new experimental metrics for wind turbines: the Pedersen method for low frequencies and the LeGarth method for swish analysis. By making these widely available the noise industry can contribute to test and evaluation of these techniques, and help drive suggestions for possible improvements more rapid implementation.

In addition, for impulsive sound, noiseLAB supports the Nordic ACOU 112 standard.

noiseLAB provides powerful, Class 1 Recording and Analysis of noise and vibration signals and their human impact. The same analysis can also be made on imported .wav files.
