We usually hear sound of splash when we pour water in a container.How can we pour water in a container without making noise?

I think that the answer may be to pour it infinitesimally slowly.Am I correct?

  • $\begingroup$ Re, "infinitesimally slowly" If you try to pour water very slowly, then surface tension will break the stream of water into a sequence of drops. $\endgroup$ – Solomon Slow Oct 8 '19 at 17:29

Do it in the vacuum. Since sound is the mechanical wave, you just need to prevent it from propagate mechanical vibration to your ear.

There will always be some sound produced when you pour the water. You can just slowly pour the water along the sides of the container and the sound produced will be almost inaudible.
