SoundPly Technology
Dynamic Sound Control™ (DSC)
Elevating Acoustics Beyond Boundaries
Imagine a space where every sound is perfectly balanced—no echoes, no unwanted reverberations, just pure, clear acoustics. Traditional materials struggle to achieve this, especially across varying frequencies and sound levels. Our patented technology uniquely combines porous and resonant absorption within a single panel, providing unparalleled sound control from the deepest bass to the highest treble. Whether it’s a bustling auditorium or an intimate conference room, SoundPly adapts to the environment, ensuring exceptional acoustic performance every time.
TRADITIONAL SOUND CONTROL
Traditional acoustic materials, such as foam, fiberglass, or felt, rely primarily on porous absorption. While these materials can be effective within specific frequency ranges, they often struggle to:
Provide Broad Frequency Coverage: Achieving effective absorption across a wide spectrum is difficult, leading to acoustically imbalanced spaces.
Absorb Low Frequencies: Many porous materials are ineffective at attenuating low-frequency sounds due to longer wavelengths, which require thicker materials for effective absorption.
Maintain Performance at Varying Sound Levels: Porous materials can become less efficient in demanding environments experiencing high sound pressure levels (SPLs), leading to compromised acoustic comfort.
Block Sound Transmission: Porous absorbers are not effective barriers to sound transmission, resulting in noise leakage between adjacent spaces.
DYNAMIC SOUND CONTROL
Dynamic Sound Control™ (DSC), addresses these limitations by combining porous and resonant absorption mechanisms within a single SoundPly panel. This synergy provides:
Exceptional Broad Frequency Absorption: Effective attenuation of across a wider range of frequency than single method absorbers.
Enhanced Low-Frequency Performance: Specifically designed features target and absorb problematic low-frequency noise.
Adaptive Performance at High Sound Pressure Levels: Maintains or even increases absorption efficiency as SPLs rise, counteracting saturation effects.
Reduced Sound Transmission: The panel’s construction acts as a barrier, enhancing sound isolation between spaces.
By solving the common acoustic challenges faced in architectural design, DSC-equipped SoundPly panels offer a superior solution that enhances the functionality and comfort of any space.
At the lowest sound levels, a micro-perforated panel absorbs the smallest percentage of acoustical energy. This is because the sound wave’s energy is below the critical threshold to propagate the evacuation and resonance of air through the panel’s micro-perforations.
This threshold is determined by several variables including the size, pattern, spacing, depth, and shape of the micro perforations, but is usually under 50 decibels.
At medium sound levels (50-80 decibels), sufficient energy exists to sustain air resonance within the micro-perforations. In this volume range, primary sound absorption occurs from acoustical energy losses through thermal and viscous friction.
At high sound levels (over 80 decibels), an additional jetting effect, called vortex shedding, becomes the dominant method of energy absorption. Air molecules are unorganized when they enter a micro-perforation, but as they flow through the perforation, the friction between the air and the perforation’s walls organize the molecules into donut-shaped rotating vortices. Due to the high level of acoustic energy contained in the vortices, they continue rotating upon exiting the perforation, and can travel a significant distance.
This jetting effect occurs on both sides of the micro-perforation, and significantly disrupts the uniformity of succeeding sound waves.
