Physical Acoustics is the base of the world's AE experts.

This group of scientists and engineers are involved in many research contracts, working closely with universities and industry to provide the best solutions in such areas as environmental safety, aging infrastructure and plant life extension. Numerous codes and standards have evolved over the past 10-15 years which incorporate Acoustic Emission technology and its applications.

Many of the top companies in such industrial fields as Aircraft and Aerospace, Petroleum and Chemical, as well as the utilities... are our best references.

Nowadays, in Europe, we have been involved in such projects as Airbus and Ariane and have performed thousands of field tests on pressure vessels and storage tanks.
