Abstract
Opera singers who pride themselves in getting sound to listeners in the back of a large opera house, 50 meters from the stage, are often surprised that their voices do not carry to those same distances outdoors.Typically, a well trained singer can produce a call or a sung tone with a sound level of 105 dB at 1 m. Based on the inverse square law, this would reduce to 99 dB at 2 m, 93 dB at 4 m, 87 dB at 8 m, 81 dB at 16 m, 75 dB at 32 m, 69 dB at 64 m, and 63 dB at 128 m. Thus, in a little more than the length of a football or soccer field, the sound level has diminished by 42 dB (Figure 1, thick line).Anff sound at 1 m has become a ppp sound at a little over 100 m. The environmental noise floor in most outdoor venues would be on the order of 40-50 dB, giving the listener a signal-to-noise ratio of only 10-20 dB.
