For example, the Boeing 707 is a Stage I aircraft–the noisiest the Boeing 727 and DC-9 are somewhat quieter Stage II planes and the Boeing 767 is a relatively muted Stage III aircraft. In 1977 the FAA designated three stages of aircraft, judged by their noise levels. In the early 1970s, prompted by homeowner complaints of noise near airports, Congress gave the Federal Aviation Administration (FAA) authority to set noise standards for new airplane designs. Internal combustion generates noise, and the combustion needed to get a loaded 727 off the ground is considerable. Morrison, Clifford Winston, and Tara Watson (1999), regulating airplane noise has cost $10 billion–twice as much as the most generous estimate of the benefits. According to recent research by Steven A. Given the racket that people raise over airport noise, one would think that the social benefits of regulating airport noise must be great. So far, the federal government hasn’t sought to regulate the decibel output of Metallica or Fido, but it does restrict the noise that airplanes may generate. One of the most ubiquitous is noise–from truck and automobile traffic, neighbors’ stereos, barking dogs, and for some people, takeoffs and landings of commercial aircraft. ![]()
