The invention provides an apparatus and method for reducing a volume of sound that travels away from a volume of space that is proximate to an instrument, while limiting an amount of physical contact with the instrument and limiting change to characteristics of the sound being produced by the instrument.

Apparatus for sound volume reduction

Systems and methods for controlling stray light reflections are provided. An optical system includes an aperture having an optical axis passing therethrough, one or more optical elements disposed along an optical path, and a detector disposed along the optical path. The system further includes an optical housing disposed between the aperture and the detector. The interior surface of the optical housing includes a predetermined surface feature adapted to control reflections of stray light along the optical path between the aperture and the detector. A method of fabricating an optical housing includes forming a pattern comprising a predetermined surface feature on an interior surface of the optical housing. The predetermined surface feature is configured to control reflections of stray light along an optical path between an aperture at a proximal end of the optical housing and a detector at a distal end of the optical housing.
