12-27-2005 Acoustic Measurements 100 Meters from Exit

These measurements were taken 111 yards from the exit as measured by a laser range finder reflecting off a flier. The flier was in the air when we took the measurements. When these measurements were taken it was 61 degrees F., 34% relative humidity, and 29.93 barometric pressure with no wind. At this location we were 95 yards from the intake. From here the compass heading to the flier was 84 degrees. The ambient noise was 65.7 db. The noise at 605 RPM was 81.3 db or 15.6 db above ambient. The chart below shows the measurements in detail.
