Abstract: A flexible sound shielding curtain contains a plurality of sound insulating sheet inserts encased within pockets or otherwise secured on the exterior surfaces of the panels of a curtain. The sound insulating sheet inserts may be constructed of a combination of materials selected and configured such that sound impinging upon the curtain is absorbed or alternatively reflected. The sound shielding curtain can be tuned to insulate an area from a select range of frequencies inherent in select environments. Tuning may be accomplished through the selection and installation of sound insulating sheet inserts configured to reflect or absorb audible acoustical energy. The sound insulating sheet inserts are readily removable to permit periodic laundering of the curtain fabric and to provide adaptability for a number of applications. Sound shielding curtain(s) can be selected, configured, installed, and extended in such a manner as to provide sound reduction in a localized space.
