The sound intensity level of a noise, expressed as a number of decibels (dB), can be found using the formula , where is the intensity or “power” of the sound in watts per square meter. The lowercase Greek letter , represents the sound intensity level. If the sound intensity of a large orchestra was measured at watts per square meter, determine the number of decibels the orchestra produced. Then, find the number of decibels produced by a sound measured at a rock concert and the number of decibels produced by an average conversation . Compare all three results.

Determine the number of decibels produced by the large orchestra.

Determine the number of decibels produced by the rock concert.
