A Look At Noise Pollution<\/p>\n\"Noise\"\n

By\u00a0 Michael D. Shaw<\/p>\n

While most of us can readily agree on what would constitute air and water pollution, many aspects of so-called noise pollution are another matter entirely. Even if you are in the mood for some loud music, you may not like your neighbor’s particular selection of material. By the same token, a mechanic working on a race car engine\u2014and gunning it repeatedly\u2014may feel that the sound is “music to his ears,” even if those around him might not agree.<\/p>\n

Sound can be defined as “a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium, usually air.” A sound level meter is typically calibrated to display its results in decibels (dB), a logarithmic unit. On the decibel scale, the smallest audible sound (near total silence\u2014as perceived by a youthful subject) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. Interestingly, for perceived loudness to double, there must be an increase of 10 db in the sound level.<\/p>\n

Here are some typical sound level readings…<\/p>\n
