of 1.0 x 10 -2 W/m 2 has a decibel rating of 100.0 dB. Using Figure 1, this decibel rating can be combined with the frequency of 200 Hz to determine the phon rating. The coordinate point with values of 200 Hz and 100 dB lies above the 90 phon line. A reasonable estimate is that it is an approximately 100 phon sound.
