Both the Jain and scientific views agree on the basic concept that sound is in the forms of waves generated by vibrations as an attribute of physical substance, unlike some other Indian Schools of thought, (e.g. Vaisesika) which consider sound as a property of akasa (space).
If sound were generated by akasa or space (as is supposed by the Vaisesika school), sound would be still heard in vacuum. But sound waves do not travel in vacuum. In modern acoustics the sound is classified into (a) musical and (b) noises. This also agrees with the Jain view expressed earlier.
