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many data that distinguish between noise and vibration because it is outdated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'.
