发明名称 Acoustical attenuating device and chair equipped therewith
摘要 An acoustical device for reducing sound pressure levels and the potential for noise induced hearing loss comprising an arched shaped acoustic pad having an interior or frontal concave sound absorption panel and an exterior or rear convex sound shield supported by an interior frame member. Sound attenuation is accomplished by enclosing the frame with at least one layer of resilient material having a high sound absorption coefficient. The acoustic pad is affixed to the back of a musician's chair by means of a mounting device which provides a high degree of flexibility in positioning for optimal directional protection of the performer.
