Every year television stations receive hundreds of complaints about the loudness of advertisements. However, federal rules forbid the practice of making ads louder than the programming. In addition, television stations always operate at the highest sound level allowed for reasons of efficiency. According to one NBC executive, no difference exists in the peak sound level of ads and programming. Given this information, why do commercials sound so loud
The sensation of sound involves a variety of factors in addition to its peak level. Advertisers are skilful at creating the impression of loudness through their expert use of such factors. One major contributor to the perceived loudness of commercials is that much less variation in sound level occurs during a commercial. In regular programming the intensity of sound varies over a large range. However, sound levels in commercials tend to stay at or near peak levels.

Passage 2
Every year, the American Lung Association (ALA) releases its annual report card on smog, and every year it gives an "F" to over half the nation’s counties and cities. When ALA’s "State of the Air 2002" recently came out, dozens of credulous local journalists once again took the bait, ominously reporting that their corner of the nation received a failing grade. The national coverage was no better, repeating as fact ALA’s statement that it is "gravely concerned" about air quality, and neglecting to solicit the views of even one scientist with a differing view. Too bad, because this report card says a lot less about actual air quality than it does about the tactics and motives of the ALA.
The very fact that 60 percent of counties were giver an "F" seems to be alarmist. This is particularly tree given that smog levels have been trending downward for several decades. According to the Environment
A. its lack of opinions from experts
B. its focus on some irregular cases
C. its attempt to make up the date
D. its inconsistent smog standards
