Acoustical Fabrics and Foam

Fabrics play an important role in controlling the acoustics of many architectural environments: theaters, concert halls, auditoriums, event spaces, meeting rooms, churches, recording studios, museums, restaurants and more.

Performance venues in particular have exacting acoustical requirements that require adjustment depending on what is presented. Curtains and fabric panels are easily adjusted, relatively economical and often an integral design element.

The fabrics below are widely used for sound absorption. See the chart for acoustic ratings for each fabric, tested using a 100% fullness, pleated panel. More complete test information is available in "PDF format" on each fabric product's detail page. Just click the fabric name below to get to the detail page and see the PDF link below the product image on that page.
