  1. Room Acoustics By: Tae & Tay

  2. The first zone is below the frequency that has a wavelength of twice the longest length of the room. In this zone sound behaves very much like changes in static air pressure. • Above that zone, until the frequency is approximately 11,250(RT60/V)1/2, wavelengths are comparable to the dimensions of the room, and so room resonances dominate. • The third region which extends approximately 2 octaves is a transition to the fourth zone. • In the fourth zone, sounds behave like rays of light bouncing around the room.

  3. Room Acoustics • Describes how sound behaves in a closed space. • The way that sound behaves in a room can be broken up into nearly four different frequency zones • The sound wave has reflections at the walls, floor and the ceiling of the roof.

  4. Natural Modes • The incident wave then has interference with the reflected one • This action creates what is called a standing wave that generate nodes and high pressure zones
