日本积水树脂公司与信乐陶瓷试验厂和丸加制陶公司合作,最近在世界上首次开发成功吸音瓷砖. 这种瓷砖可供既要美观又要音响效果好的音乐厅和礼堂用作壁面装饰。它是用日本信乐地厂区特产的陶土与特种原料(二氧化硅系火山灰等)混合,经施釉后在1200℃高温下烧制而成的,烧制时,占瓷砖总体40——50%的火山灰形成无数可以吸音的微孔。这种瓷砖直接贴在灰浆底子上时,对中、高音域的吸音效果好,频率800赫兹左右的吸音率为80%.也可用混凝土块托底,使之背面形成40厘米厚的空气层,此时从215赫兹低音域
Japan Sekisui Resin Co., Ltd. cooperates with Shiner Ceramics Experimental Factory and Maruka Ceramics Co., Ltd. and recently developed the world’s first sound-absorbing ceramic tile. This type of tile can be used as a wall decoration in both concert halls and auditoriums that are both beautiful and acoustically sound. . It is made by mixing the clay and special raw materials (silica fume, etc.) of the specialties of the Shinraji plant in Japan, and firing them at a high temperature of 1200°C after glazing. When firing, it accounts for 40 to 50% of the total ceramic tile. The ash forms numerous sound-absorbing micropores. When the tile is directly attached to the mortar base, the sound absorption effect in the middle and high ranges is good, and the sound absorption rate is about 80% at a frequency of about 800 Hz. Concrete backing can also be used to form a 40 cm thick air layer on the back side. At this time from 215 Hz bass range
