There are a large number of SAMURAI Software Options that have specific application to noise and vibration measurements using the NoisePAD.

The software options are listed below (refer to the detailed description on the SAVTEK Sales web pages, or the SINUS Messtechnik GmbH website for further information, or call SAVTEK on Ph +61 7 3300 0363 or email dwatkins@savtek.com.au).

The base functions of SAMURAI software used by the SINUS data acquisition devices includes:

Sound Level Meter, 1/3 Octaves, FFT analysis, Reverb Time, Time History, Wav recording

Other SAMURAI software options available include:

1. BUILDING ACOUSTICS (SAMBA) – measurement according to ISO 140 & ISO 717. For determination of the acoustical properties of rooms, dividing walls, structural elements and building materials.
2. BUILDING VIBRATION – for measurements according to DIN 4150 and DIN 45669. This option allows the measurement and analysis of building vibration according to DIN 4150 for the purpose of the evaluation of its effects upon buildings and structures as well as people within them.
3. ROOM ACOUSTICS – allows for calculation of STI, STIPA, RASTI and C50, C80
4. BEARING ENVELOPE DEMODULATION – allows for assessment of rolling element bearing faults
5. FRACTIONAL OCTAVES – 1/1, 1/3, 1/6, 1/12, 1/24, 1/48 octaves according IEC 61620 in real-time
6. HVMA – Human Vibration Multi Analyzer Software (3/6 channels) ISO 8041
7. LIVE SOUND POWER – measurement of sound power in real-time
8. MULTI-GENERATOR – sine, rectangle, triangle, multi-sine, sine-sweep, pseudo noise …
9. NOISECAM VIDEO – allows for video documentation, files export, simple USB camera included
10. ORDER TRACKING – order tracking from FFT allows for the investigation of vibration events and noise emissions in relation to rotating machines or equipment. In contrast to the FFT, not the level at a given frequency (FFT spectrum) but instead the level at a multiple or fraction of the basic rotational speed (order spectrum) is of interest here. For example, this technique can be used to locate gearbox damage.
11. POST PROCESSING – allows for new analysis to be conducted from time signal of a previous recording and data import.
12. PSYCHO ACOUSTICS – measurement of loudness and sharpness in real-time
13. SOUND INTENSITY – Sound Intensity measurement in FFT and 1/3 octaves within SAMURAI
14. SOUNDPOWER ISO 9614 – Sound Power according to ISO 9614 Part 1 & 2), opt. Sound Intensity required.
15. SOUND INTENSITY MAP – semiautomatic Pressure or Intensity Map in Post-Processing uses a camera to take photo of object or area and the user defines the measurement points.
16. SOUND POWER ISO 3744/45/46 – external program that allows for calculation of online sound power measurement with microphone hemisphere
17. TIME SYNCHRONOUS AVERAGING – often used for rotating machinery to help analyse gear faults. The FFT data is linked to a reference rotation to enable it to extract the repeated parts of the vibration signal from the complex background noise.
18. TONALITY ISO 1996-2 – allows for assessment of tonality of signals according to ISO 1996-2 Appendix C. The result is obtained from the FFT curve.
19. TRANSFER FRF – data acquisition with impact hammer and accelerometer to calculate transfer functions
20. VIBRATION METER – single & double integration of acceleration levels including filters according to ISO 10816. Optimised for machine vibration.
21. VIRTUAL TACHO – RPM calculation from the signal based on FFT analysis
22. WEATHER STATION – integration of data and support of weather stations from Thies NHTBF and Vaisala WXT520
23. ZOOM FFT – allows for FFT analysis of a smaller frequency range using more lines that full spectrum FFT – 100-6400 lines

Training in the use of the NoisePAD and each SAMURAI module proposed to be utilized is included in the rental charge.

A variety of acoustic and vibration sensors which connect to the NoisePAD are available for rent from SAVTEK .
