You are standing 1.00 meter jackhammer. You experience level of 130 decibels. (Point A) from a a sound intensity Point A Point B Calculate the Intensity I (W/m²) of the jackhammer at Point A. To protect your hearing, you walk away from the jackhammer until the Intensity Level is 60 decibels (i.e., PB = 60 db). Calculate the Intensity I (W/m²) at this new location (Point B). Calculate Point B's Location r {m} where the Intensity Level is 60 decibels.

Seiche

A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
