Should I use sound or vibration measurements to improve my QC process ?

Depending on the local situation it can be better to use either noise or vibration measurements to find faulty products coming from your production line.

Sound measurements are good if the background noise around the place where you are performing the sound measurements is low compared with the sound levels that you will measure from your product.

If the background noise is too high, it will influence the measured sound levels and you will get false ‘No Go’ warnings which will slow down the process.

For situations with a relative high background noise level the vibration measurements are recommended, they measure the vibrations of the product with an accelerometer and compare it with a reference spectrum.

It’s a 1 channel vibration accelerator meter.
