Further audio analysis techniques

Post by Steve Smith »

We often talk about “New Feature Requests” when handling customer feedback and technical support queries. In a nutshell, PicoScope is constantly evolving and trying to keep pace at times is challenging (I am thinking predominately of PS7 at present)

NVH is another example where New Features are being requested and of course “queued” for development along with other requests.

Spectrograms/Heat maps are one such new feature request that will eventually make into our NVH software but in the interim, there are other audio analysis software packages that provide a number of niche analysis features that Ben and I use when handling NVH cases

Sonic Visualiser and Audacity are both exceptional examples of such software and both focus on the manipulation of sound which you may rightly think is beyond the realm of automotive applications.
However, take a look at the video below where I have exported our NVH sensor data in .wav format and then analyzed further with Audacity

I hope this helps, take care……Steve

Sorry Steve but I have to disagree with your diagnosis on this occasion.

You have conclusively proved that the issue is a duck tapping a wooden spoon on the inside of the bell housing. :lol: :lol: :lol:

Hope you and yours are surviving the strange times we live in. 8)

Kev.

The more I played that audio back the more it reminded me of old bed/mattress springs, which is another discussion entirely!

We are marching on here, I have no doubt you are too

Take care.....Steve
