Plane builders themselves long ago recognized the noise problem, went to work developing suppressors that would cut the roar and whine of pure jet engines without cutting engine efficiency too much. Last week Boeing announced that it had licked the problem. It said that its suppressor had cut jet noise below the level promised purchasers of the 707, making it slightly less noisy than a Super Constellation. The trick was done by breaking up the jet stream and funneling it through 21 narrow after tubes instead of one big tube. "The big, doughnut-shaped exhaust roar," said...
Even the highly critical Port Authority admitted that the suppressors have reduced jet noise at the normal measuring distance to 102 decibels, about the level of a piston-engine airliner. But it has also thrown a new factor into the dispute; the Authority argued that the results of tests it had made showed that the jet noise contained a high-pitched whine that made it much more objectionable to listeners than a piston-engine plane roar of a much higher decibel reading. But the Authority's own aviation-development specialist, Herbert O. Fisher, apparently disagreed. He joined with outside...
