AcousTech™ Low Frequency Absorption Wall & Ceiling Panels are decorative and highly customizable panels that are designed to absorb low frequencies without removing high frequency energy from a space. The exception is the ATP 2.0 LBB, which is a broadband absorber for balanced absorption of both lows and highs. With the outward appearance of a standard wall panel for both wall and ceiling applications, all low frequency models feature a damped, select-tuned membrane resonator that is extremely effective at absorbing sound energy below 150 Hz. 


AcousTech™ Low Frequency Absorption Panels are the ideal decorative wall & ceiling treatment for areas that require low frequency sound & noise control. Some applications include:

Music Rehearsal Space — Auditoriums — Churches — Media Rooms — Studios — Schools
