![]() Here we export the captured data from PicoScope NVH and utilise the noise cancelation features of Audacity or Sonic Visualiser topic22151. Noise cancelation with 3rd party software The following forum post covers filtering within NVH post49441.html#p49441ģ. Using the NVH filtering feature we can remove the desired amount of ambient noise in order to focus on the frequencies of interest The following link will help topic21639.html wav file for playback in a 3rd party media player. ![]() (Ensure you inform the software you have a microphone connected as well as an accelerometer in order to expand the spectrum to 20 kHz)įor example, listening to wheel bearings can be achieved with a microphone but the ambient noise can become overwhelmingĪttaching an accelerometer to the structure of interest (hub assembly in the example above) and listening to the captured data will remove a large proportion of ambient noiseĪlternatively, you can Export your connected accelerometer data as a. Using an accelerometer as a microphone is great for “listening” to audible structure borne frequencies up to 2000 Hz. in Essentia, including the generic IIR filtering, first and. In the meantime we have a number of ways to combat ambient noise which can be a real nuisance during post capture analysisġ. to be used with Sonic Visualiser for visualization purposes. Display for monitoring the in-going and out-going signal. 5 filter types including Low Pass, High Pass, Band Pass, Notch, and Peaking. Two modules - Filter bank on the left, multi-mode filter on the right. I will share this with the software team ASAP Endless controls for filtering anything - Accurately filter any frequency/frequencies you like. The ability to “zero out” ambient noise and vibration prior to recording could be very helpful indeed. What you have described Calek is great new feature request that does not yet exist within our NVH software. Hello and thank you for the post and your feedback using PicoScope/NVH
