Using a light and bell positioned at the end of the Festival Pavilion, this exhibit enables visitors to investigate how sound perception outdoors can be affected by distance, wind, and temperature. Another aspect of the exhibit allows visitors to use their cell phones to measure the time it takes the sound of a Golden Gate Bridge foghorn to reach them in different parts of the City.
