See the THX Guide. Thank you. A room whose dimensions are multiples of each other - for example, 10 feet by 20 feet - is nearly as bad as a cube because many of the same frequencies are emphasized. Next, take the ceiling height and multiply it by the second ratio, to get room length. The axial, tangential, and oblique room modes of rectangular homogeneous rooms are computed.Axial room modes hit on two facing surfaces.Tangential room modes hit on four surfaces and oblique room modes include six surfaces crosswise. A room in room construction is built in a room with a floor area of 30m2 and a height of 4,8m. Oblique Modes - Involve all six surfaces - four walls, the ceiling and the floor.
