Warnings
The Sound Pressure Level,
LpA, of this condition exceeds
the suggested limit of 110 dBA (normalized at 1 meter with STD pipe schedule).
Additional source noise attenuation is required; path treatment is not
appropriate. Note: Your noise
prediction may be less than 110 dBA because you input a distance greater
than 1 meter, or the pipe schedule
input is greater than STD.
