Acoustic panels (also sound absorption panels, soundproof panels or sound panels) are sound-absorbing fabric-wrapped boards designed to control echo and reverberation in a room.{{Cite book|last1=Architects|first1=American Institute of|url=https://books.google.com/books?id=7s6h--TUWiwC&q=acoustic+panel+assembly&pg=PA47|title=Architectural Graphic Standards for Residential Construction|last2=Giglio|first2=Nina M.|date=2010-04-26|publisher=John Wiley & Sons|isbn=978-0-470-39583-7|language=en}} Most commonly used to resolve speech intelligibility issues in commercial soundproofing treatments. Most panels are constructed with a wooden frame, filled with sound absorption material (mineral wool, fiber glass, cellulose, open cell foam, or a combination thereof) and wrapped with fabric.{{Cite book|last=Binggeli|first=Corky|url=https://books.google.com/books?id=qePlJk8SRkoC&q=acoustic+panel+assembly&pg=PA217|title=Interior Graphic Standards: Student Edition|date=2011-12-29|publisher=John Wiley & Sons|isbn=978-1-118-09935-3|language=en}}

An acoustic board is a board made from sound absorbing materials, designed to provide sound insulation.{{cite book |title=Dictionary of architectural and building technology |publisher=E & F N Spon |location=London |year=1998 |pages= 3|isbn=0-419-22280-4 |url= https://books.google.com/books?id=Jgm6J9UOB3MC&q=%22acoustic+board%22&pg=PA3}}{{cite book |author1=Derek Butterfield |author2=Alf Fulcher |author3=Rhodes, Brian |author4=Stewart, Bill |author5=Derick Tickle |author6=Windsor, John C. |title=Painting and Decorating: An Information Manual |publisher=Blackwell/Futura |year=2005 |pages= 145|isbn=1-4051-1254-9 |url= https://books.google.com/books?id=DyHKWxQD0NQC&q=%22acoustic+board%22&pg=PA145}} Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, when sound passes through an acoustic board, the intensity of sound is decreased. The loss of sound energy is balanced by producing heat energy. They are used in auditoriums, halls, seminar rooms, libraries, courts and wherever sound insulation is needed. Acoustic boards are also used in speaker boxes.
