Helicopter Noise

Paper Summary:

Today, with every television news station, radio station, police department, traffic reporter, life-flight rescue and emergency units circling above, helicopter roter sounds have become an annoyance to the public. The paper shows that this has led to an increase in local restrictions and tighter certification standards, forcing manufacturers to seek new technology for sound abatement. The paper discusses the three noise categories and modern noise reduction technologies.

From the Paper:

"Helicopter noise reduction has become so important to rotorcraft manufacturers that competition has ignited advertising campaign wars with each claiming one or more of their models to be the quietest in the industry (Kernstock 1999). he competition is so great in many cases that many helicopters are "within a tenth of a decibel of each other far below human hearing thresholds" (Kernstock 1999). This advent of low-noise technology has created two classifications of rotorcraft, the new quiet crafts that meet new regulations and the older noisy ones that continue to operate under grand-fathering clauses yet may be prevented from being introduced into new markets (Kernstock 1999). Moreover, as anti-noise regulations increase, the older grand-fathered craft could eventually become prohibited in many areas, causing serious consequences for many operators who cannot afford the newer models (Kernstock 1999)."
