Acoustic Screens for Sound Transmission Control
Acoustic Screens and Enclosures offer complete mobility for maximum accessibility. Both offer rugged all-welded steel tube frames and optional heavy duty caster. While most applications require our high performance or acoustical composite panels, ANC-QFA sound absorption panels are also available.
The modular screen frames can be arranged in various configurations to provide noise control around various noise problems in any environment.

These acoustic barriers are highly noise absorbent, quilted fiber glass blanket designed to absorb unwanted sound reflection in a variety of applications.
For maximum noise reduction ( 20 db(A) + ), we recommend complete enclosures. These complete enclosures still do offer different configurations for visibility, ventilation and adequate access.
Partial acoustic enclosures can still offer noise reduction of 15 db(A) + while only having 2, 3 or a 4 sided (without roof) enclosure.
