Question
Dear Prof Cleggsan

Is Sound a scalar or vector?.

Thanks
Prashant

Answer
Yes, sound is either a vector or scalar.

Vector is by definition a magnitude with an associated direction.
Scalar is a magnitude number only with no direction involved.

Sound  emanates at a certain level or magnitude in, say, loudness.  That is a scalar quantity.

A sound reproducer may be aimed at a certain direction and the reception of that sound by a microphone at the specified angle may detect the arrival of the sound at a given magnitude of loudness at the specified angle.  That would be a vector.

So, it can be either or both, depending on the context and application to the problem at hand.
