Homework 7: Logs, Decibels and pH
Decibels are a measurement of sound intensity. The logarithmic relationship between intensity of a sound and sound level in decibels is given by the following formula:
L = 10 * log (I/Io)
L is the sound level in decibels, I is the intensity of the sound, and Io is the intensity of the softest sound that can be heard by humans.
I/Io is a ratio. This ratio is how many times louder a sound is than the softest audible sound. For this activity, we will only consider the ratio and not the individual pieces of the ratio.
