摘　　要：Horeq隔声砂浆是一种新型建筑材料。重点介绍3种墙体构造(裸露条板、条板+普通砂浆、条板+Horeq隔声砂浆)的试验室隔声测试及隔声数据的对比分析。通过对试验数据计算可知,对于普通砂浆25mm抹面条板,隔声量较裸露条板提高约4dB;而隔声砂浆25mm抹面条板,其隔声量较裸露条板墙高8dB。Horeq sound insulation mortar is a new acoustic building material.The sound transmission losses in the acoustic lab of 3 wall structures（bare wall slab,wall slab with normal mortar,wall slab with sound insulation mortar） were introduced and compared.According to test result,the sound transmission loss of 25mm wall slab can be improved about 4dB by brushing normal mortar,and it could be improved 8dB by brushing Horeq sound insulation mortar.
