Glossary of Terms


Gobo is a slang term used by sound recording engineers to refer to a movable acoustic isolation panel.

An acoustics gobo is parallel in use to a photography gobo, which is used to block direct light sources, and also shares its name with the stage lighting gobo. The origin of the term "gobo" is obscure, but is most likely short for "go-between." The gobo was invented by Charles Norris Hoyle, and was originally a product of TayTrix.


A luthier (/ˈluːtiər/ LOO-ti-ər)[1] is someone who builds or repairs string instruments generally consisting of a neck and a sound box. The word "luthier" comes from the French word luth, which means lute. A luthier was originally a maker of lutes, but the term now includes makers of stringed instruments such as the violin or classical guitar. A luthier does not make harps or pianos, as these require different skills and construction methods because their strings are secured to a frame.
