Notes about Sound
pressure level
All noise emission measurements were taken at a distance of 3
feet from the FDB-AC and at a height of 5 feet from the floor. The
FDB-AC was mounted on a laboratory test-bench. No barriers or
noise-reduction facilities were used except for exhaust return to
an oil-recovery-unit located beneath the test-bench. A drive
pressure of 75 psi was applied (full FDB-AC drive pressure). No
axial force pressure was applied. The FDB-AC was running at full
idle speed. Because the working environment is not known, this
method was considered the best method for measurements.
The equivalent continuous A-weighted sound pressure level was
measured as 75 dB (A).
The peak C-weighted instantaneous sound pressure value was
measured as 87 dB(C).
