The invention provides a light sound insulation fireproof wallboard which comprises an acoustic black hole board, films, sound absorption layers and surface layer boards are sequentially arranged on the two sides of the acoustic black hole board, acoustic black hole cavities are formed in the two sides of the acoustic black hole board, at least mass blocks and damping blocks are arranged in the acoustic black hole cavities, the mass blocks are connected with the films, and the damping blocks are connected with the films. The damping block is connected with the bottom of a cavity body of the acoustic black hole cavity; according to the light sound-insulation fire-resistant wall plate, by means of the good broadband sound insulation effect of the acoustic black hole structure and the low-frequency resonance sound absorption effect of the thin film with the additional mass block, a noise reduction system composed of the acoustic black hole plate and the thin film with the additional mass block has the good low-frequency interval noise reduction capacity, and meanwhile the noise reduction effect is good. A medium-high frequency interval sound insulation system is formed by the sound absorption layer and the surface layer plate, so that the sound insulation frequency band of the whole wall plate covers high, middle and low frequency intervals, the purpose of noise reduction of the whole frequency band is achieved, and the sound insulation performance of the wall plate can be remarkably improved.
本发明提供了一种轻质隔声耐火壁板,包括声学黑洞板,所述声学黑洞板的两侧均依次设置薄膜、吸声层、表层板,所述声学黑洞板的两侧具有声学黑洞腔,所述声学黑洞腔中至少设置质量块、阻尼块,所述质量块与薄膜连接,所述阻尼块与声学黑洞腔的腔体底部连接;本发明所述的一种轻质隔声耐火壁板,利用声学黑洞结构的良好宽频带隔声效果,具有附加质量块的薄膜的低频共振吸声作用,使得声学黑洞板与具有附加质量块的薄膜组成的降噪系统,具有良好的低频区间降噪能力,同时,通过吸声层和表层板形成中高频区间隔声体系,使得本申请的整个壁板的隔声频带覆盖高中低各个频率区间,达到整频带降噪目的,能够显著地提高壁板的隔声性能。
