Lab10 Sound and Earthquake Simulations

1.) Sound Intensity

The decibel level d of a sound is based on the ratio of the intensity I of that sound to the lowest threshold that can be heard by a human (intensity of 1) and can be modeled by the equation . View the following Sound Intensity Table.

2) Do you hear what I hear?

Listen to the Introduction tab of Do You Hear What I Hear? Explore and use the Hearing Response tab to answer the questions. Listen to the three speeches on the Filtered Sound tab and answer the questions.
