How To Choose Sound-absorbing Panels? Understanding These Parameters Is All You Need.

Acoustic panels are a core material for optimizing indoor acoustic environments. They reduce reverberation time by absorbing and reflecting sound waves and are commonly used in places requiring high sound quality, such as KTVs, schools, and concert halls. Their core function is to improve sound clarity and prevent echo interference, while also offering decorative and safety benefits. When choosing acoustic panels, it's crucial to consider material characteristics, structural design, and environmental protection ratings to ensure they match the functional and situational needs.

Material Composition and Acoustic Principles
Acoustic panels consist of a porous base material and a surface layer. The base material typically uses low-density materials such as polyester fiber, glass wool, or mineral wool, creating numerous tiny pores. When sound waves enter these pores, air molecules friction against the pore walls, converting sound energy into heat energy, thus achieving sound absorption. The surface layer comes in two types: fabric and leather. The porous fabric surface enhances mid-to-high frequency sound absorption; the dense leather surface primarily assists in low-frequency sound absorption and improves aesthetics. Two thicknesses, 50mm and 25mm, correspond to different sound absorption frequency ranges, with thicker panels providing more significant low-frequency absorption.

Core Parameters and Performance
In terms of physical performance, the product's bending strength and compressive strength meet high standards in the building materials industry, capable of withstanding external impacts during daily installation and use. Low-temperature bending tests show that it maintains flexibility even at -10℃, avoiding the risk of brittle fracture in northern winters. Acoustic parameters include a low thermal conductivity, indicating excellent thermal insulation and reduced energy loss; high tear strength ensures the surface layer is not easily damaged by frequent contact. The product is E1 certified, with formaldehyde emissions below 0.124 mg/m³, meeting safety standards for long-term indoor use.

Installation Methods and Scene Adaptation
Before installation, the required sound absorption area should be calculated based on the space volume; it is generally recommended to cover 30%-50% of the wall surface. The product supports two installation methods: surface mounting and concealed mounting. Surface mounting involves directly fixing the panels to the wall with special adhesive or pneumatic nails, offering quick installation; concealed mounting requires a pre-installed frame, with the acoustic panels embedded and covered with decorative panels, suitable for places requiring high aesthetic standards. For entertainment venues such as KTVs, a combination of 50mm thickness and leather finish is recommended to enhance low-frequency absorption and improve aesthetics; for school classrooms, a 25mm thickness with fabric finish is recommended to balance cost and meet mid-to-high frequency sound absorption requirements. During installation, avoid damp areas to prevent the base material from absorbing moisture and deforming.
