Sound Absorbing Material, Sound Absorbing Panels [205kg/m³ High Density, 30cm x 40cm / 20 Sheets, Installation Surface

【205kg/m³ High-Density Sound Absorption Panel】Actual measured density of 205kg/m³. Many commercially available panels with a density of 200kg/m³ may have lower actual densities and weaker sound absorption capabilities. Our 205kg/m³ panels optimize the balance between airflow and fibers, efficiently absorbing mid-to-high frequency sounds. They reduce echoes and reverberation, creating a clearer and more pleasant sound environment.
【Sound Absorption Principle】When sound passes through the fibers within the panel, friction converts vibrational energy into heat. In lower-density panels, air passes through too easily, resulting in insufficient friction and weak sound absorption. Conversely, if the density is too high, air cannot pass through easily, leading to increased reflection. A density of 205kg/m³ is optimized for peak sound absorption efficiency.
【Also Provides Soundproofing Effect】The 205kg/m³ high-density sound absorption panel, due to its mass, suppresses the transmission of high-frequency sounds (such as conversations and TV audio), also providing a soundproofing effect. Combined with the sound absorption effect of the internal fibers, it simultaneously reduces indoor reflected sound and reverberation, creating a more comfortable acoustic environment. *Note: Sound insulation for low frequencies (heavy bass) may be insufficient with this panel alone. We recommend using it in conjunction with soundproofing sheets if necessary.
【Eco-Friendly, Flame-Retardant Material】The sound absorption boards are made from high-quality polyester fibers that do not contain harmful substances like formaldehyde, making them environmentally friendly and highly flame-retardant. Ready to use immediately upon opening, with no odor. Features a self-adhesive design, eliminating the need for additional tape or glue. Simply peel off the backing paper and stick. Easy installation for anyone, as long as the surface is clean and dry.
【Versatile Sound Absorption Panel】Ideal for reducing echoes in home studios and streaming rooms, improving voice clarity for telework and online meetings, and enhancing acoustics in conference rooms and classrooms. Also effective for reducing stress from everyday noise in apartments. Its stylish design blends naturally with your interior decor, upgrading your room's atmosphere while improving its sound environment.
