Acoustics is a branch of physics that studies sound, namely mechanical waves in gases, liquids, and solids. A scientist that works in the field of acoustics is an acoustician. The application of acoustics in technology is called acoustical engineering. There is often much overlap and interaction between the interests of acousticians and acoustical engineers.
...*coustics is characterized by its reliance on combinations of physical principles drawn from other sources; and that the primary task of modern physical acoustics is to effect a fusion of the principles normally adhering to other sciences into a coherent basis for understanding, measuring, controlling, and using the whole gamut of vibrational phenomena in any material.Origins in Acoustics.

Acoustical Detection of Aircrafts - From the first world war until the 30's air acoustics played an important role in the air defence. As radar was still to be discovered, vision had to be supplemented by hearing using the sound of the engines. (MUSEUM WAALSDORP: TNO-FEL Museum).
Chirped Echo from the Mayan Pyramid of Kukulkan at Chichen Itza - David Lubman of the Acoustical Society of America argues that the echo sounds like the primary call of the Mayan sacred bird, the Quetzal.
