Sound is produced by collision or separation of two or more physical objects.

It is of two kinds (in respect of genesis)-1 Natural or spontaneous, e.g. thunder and (ii) that produced by conscious effort. The latter is again of two kinds - (i) lingual and (ii) non-lingual4. The lingual sound is again of two kinds -(i) articulate i.e. made up of alphabetical composition, and (ii) inarticulate i.e. sound produced by subhuman animals..
