安裝聚酯纖維吸音板時，板與板之間是否應該留有縫隙？

背面的空腔及其形成的空間吸音層可顯著提高材料的吸音性能。在空腔內填充吸音棉可顯著提高吸音性能，尤其對低頻聲音的吸收效果較佳。

They exhibit significant absorption of mid-to-high frequency sounds (500Hz-4000Hz), with an absorption coefficient exceeding 0.7. This effectively reduces echo and reverberation, improving sound clarity. Within the 125Hz-4000Hz noise range, the absorption coefficient can reach a maximum of 0.8 or higher.

聚酯纖維吸音板的主要功能是吸音，而非隔音。如果厚度達到25毫米或以上，密度較高，且安裝時縫隙密封良好，則可以降低部分空氣傳播噪音，但無法阻隔結構性傳播的聲音（例如樓上腳步聲通過地板傳播）。吸音和隔音是兩種不同的聲學概念，請根據您的實際需求選擇合適的產品。

適宜的安裝環境溫度為15-30℃，濕度為40-60%。避免安裝在潮濕或未乾燥的牆面上，以防止板材變形或發黴。

Yes. Before installation, the wall surface should be thoroughly prepared to ensure it is flat and clean, thus enhancing the adhesion. An uneven wall surface will result in the panels not adhering tightly to the wall, affecting both sound absorption and aesthetics.

Warping is usually caused by poor-quality adhesive or uneven application. Use high-quality, environmentally friendly adhesive and apply it evenly. After installation, apply appropriate pressure to ensure a tight bond between the acoustic panels and the adhesive.
