Students perform a simulation to measure the sound intensity at different distances from the source of the noise, and then use the data to develop an inverse variation model.

• Student will perform a simulation to measure the sound intensity at different distances from the source of the noise.
• Students will use the data to develop an inverse variation model. 
• Students will verifying the model and use it to map safe and unsafe zones based on sound-intensity restrictions.

• inverse variation
• direct variation

This activity is based on an impact study to address the concerns of the residents of a community near an airport.
