SoundPly LR Series Micro-Perforated Acoustic Panel

The LR Series is the newest addition to the revolutionary class of SoundPly acoustic panels, engineered to provide maximum acoustic effectiveness throughout the full range of sound pressure levels.

Leveraging several of the groundbreaking technologies developed for the RF Series of SoundPly panels, the LR Series provides near anechoic-grade sound absorption at a price point unheard-of for micro-perforated acoustic panels.

DISPENSING WITH CONVENTION.

Unlike traditional acoustic panels used in ceiling and wall systems, the LR Series does not require an enclosed plenum/cavity space behind it to absorb sound, allowing for new ways to integrate the panels into an environment.

SoundPly LR panels come in either 1” or 2” thicknesses and are available with micro-perforations on one or two sides. Since LR panels can be freely suspended and provide excellent absorption on both sides, they are ideal for use in open office solutions such as baffles, beams, grids, clouds, or open-reveal planks.

BEYOND ACOUSTICS.

Like the other SoundPly series of panels, the LR series can be provided with a single primer coat, or top-coated in a full spectrum of painted colors and sheens.  Custom graphics and images in sizes up to 4′ x 8′ can be printed on the panels using a 1200dpi, UV-cured printing process.

Among all the surface treatment options, the most popular for SoundPly panels is wood veneer.  Hundreds of real wood and reconstituted veneer species are available in stock, and can be finished in a variety of clear or custom stain finishes.

LR SERIES TECHNOLOGIES

The LR Series panels feature MicroPerfection® technology, resulting in the most advanced, effective micro-perforations ever integrated into an acoustic panel. Achieving maximum acoustic performance required engineering a process to precisely manufacture a new type of micro-perforation—one that’s smaller, cleaner, and three times deeper than any currently produced.

A key component of MicroPerfection technology is the panel’s percentage of effective micro-perforations. Over 99.97% of the micro-perforations on SoundPly panels are open and functional— a distinct advantage over the 35-38% of open micro-perforations on other manufacturer’s acoustic panels.

Dynamic Sound Control provide uniform sound absorption across all volume levels.

Dynamic Sound Control is one of the most significant benefits of the LR Series’ highly effective use of porous and resonant sound absorption. Most types of sound absorbing materials, including porous materials, experience a reduction in absorptive capacity in response to an increasing sound pressure level (SPL). Resonant absorption does the opposite.

An increase of SPL causes the principle form of acoustic energy conversion to shift from thermal viscous friction —occurring inside the passages of each micro-perforation— to a more effective and sound wave disrupting process called vortex shedding, which occurs at the outlets of each micro-perforation.

As sound levels rise, the diminishing effectiveness of porous absorption is offset by the improved efficiency of the resonate absorption. By providing more uniform absorption across the full spectrum of decibel levels, Dynamic Sound Control helps prevent environments from sounding too “dead” at low sounds levels, while supplying excellent absorption at high sound levels, when it’s needed most.

SP Acoustic Core Technology

The advanced SPCore technology is responsible for the LR Series panels being 5x stronger, 60% lighter, and over 2x more dimensionally stable than other acoustic panels. The face and back of every LR panel consists of a fiberglass-reinforced sandwich of durable, dimensionally static composite layers. A combination of pressure and heat fuse the outer layers to the inner core’s structural components, resulting in a uniformly sealed, torsionally rigid, monocoque structure.
