Glossary
Acoustics Higher-frequency sound waves travel in straight paths and are easily deflected and reflected by hard surfaces. They are also easily absorbed by porous fibrous materials. Lower-frequency sound waves (below 100 Hz) spread widely, so they are not impeded by obstacles and are less readily absorbed. As sound waves meet nearby materials, they are selectively absorbed and reflected; the reflected sound′s quality is modified according to the surfaces′ nature, structures, and shapes. The acoustic characteristics of scenery, furniture, drapes, and people further modify audio quality.
Action line (line/eye line) The imaginary line along the direction of the action in the scene. Cameras should only shoot from one side of this line.
