BISOPE series 8- Difference Between Vibration and Noise (Vibration versus Noise)

-----------------------------------------------------------------------------------------------------

Is the difference between vibration and noise simply the difference between touch and hearing? The main reason is that there are not many data that distinguish between noise and vibration because it is outdated and there is no reason to distinguish it. However, if you actually look at it from various aspects, you can clearly mention the difference, and the fact that there aren't many people who specialize in both fields is probably the reason for the distinction between the words 'noise' and 'vibration'.
