       This would put (0.49)(340) = 167 ft  on the ceiling, (0.3)(340) = 102 ft  distributed between the

    east and west walls, and (0.21)(340) = 71 ft  distributed between the north and south walls. This
    recommendation should provide the desired results, but some experimentation, and critical
    listening, should be included in any such project to account for other variables. For example,
    different placements of absorptive materials in a room will affect the amount of absorption they
    provide.
