Every year television stations receive hundreds of complaints
about the loudness of advertisements. However, federal rules forbid
the practice of making ads loud than the programming. In addition,【S1】______
television stations always operate at the highest sound level allowing【S2】______
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 variety of factors in addition to【S3】______
its speak level. Advertisers are skilful at create the impression of【S4】______
loudness through their expert use of such factors. One major
contributor of the perceived loudness of commercials is that much【S5】______
less variation in sound level occur during a commercial. In regular【S6】______
programming the intensity of sound varies over a large range.
However, sound levels in commercials tend to stay at or near peak
levels.
Another "tricks of the trade" are also used. Because low-【S7】______
frequency sounds can mask higher frequency sounds, advertisers
filter out any noises in that may drown out the primary message. In【S8】______
addition, the human voice has more auditory impact in the middle
frequency ranges. Advertisers electronically vary voice sounds so
that they stay within such a frequency band. Another approach is to
write the script in which lots of consonants are used, because people
are most aware of consonants than vowel sounds. Finally,【S9】______
advertisers try to begin commercials with sounds that are highly
different from that of the programming within which the commercial【S10】______
is buried. Because people become adapted to the type of sounds
coming from programming, a dramatic change in sound quality
draws viewer’s attention. For example, notice how many
commercials begin with a cheerful song of some type.
