How are volume and amplitude related?

The higher the amplitude the higher the volume. bigger sound wave = louder noise.


Why does air escaping from the open end of small pipe make a lot more noise than air escaping at the same volume rate from a large piece?

Sound waves are produced from disturbances in the pressure of an environment ( which is why in space, no one can hear you scream...theres nothing to be disturbed by your scream). So, if the same volume, and therefore the same mass, of air is escaping from a smaller opening, the pressure disturbance is magnified since the pressure the air exerts on the atmosphere around it is greater.

Of course soundproof foam will reduce the noise escaping from the room. If you cover the walls and ceiling there will be very little noise escape through the floor.
