SEA originated in the aerospace industry in the early 1960s. Today AutoSEA is applied to a large variety of products, from cars and trucks to aircraft, spacecraft, electronic equipment, buildings, consumer products and more.
SEA is based on the principle of energy conservation.
All the energy input to a system, through mechanical or acoustic excitation, must leave the system through structural damping or acoustic radiation. The method is fast and is applicable over a wide frequency range. SEA is very good for problems that combine many different sources of excitation, whether mechanical or acoustic. There are many references available on the subject of Statistical Energy Analysis. These icons are connected in a network to represent the possible exchange of vibratory or acoustic energy.
