margin: 0px;"><o:p></o:p></p> <p style="padding: 0px; margin: 0px;">規格參數：聲屏障高度在1m一5m間，覆蓋有效區域平均降噪達10～15dB(A)(125Hz～40000Hz，1/3倍頻程)，******達20dB(A)。<o:p></o:p></p> <p style="padding: 0px; margin: 0px;">　　針孔復聲鋁板技術參數：<br> 　　1、降噪系數：75MM空腔時NRC≥0.70；<br> 　　2、隔聲量：≥30dB(A)；<br> 　　3、人工加速耐候性(250h):無粉化；<br> 　　4、耐鹽霧腐蝕性：酸性1000h，外觀評級10級，無點蝕、起泡、剝落等腐蝕現象；<br> 　　5、抗拉荷載：≥1305N；<br> 　　6、防火等級：A級不燃<o:p></o:p></p> <p style="padding: 0px; margin: 0px;">特點：質輕無污染，防眩、抗老化、抗沖擊、抗凍融、吸聲系數穩定，耐潮濕、耐腐化、易彎易加工、易運輸，拆裝維護方便，性價比合理，并可噴涂各種顏色。<o:p></o:p></p> <p style="padding: 0px; margin: 0px;">用途：聲屏障主要用于高速公路、高架復合道路、城市輕軌地鐵等交通市政設施中的隔聲降噪、控制交通噪聲對附近城市區域的影響，也可用于工廠和其它噪聲源的隔聲降噪。<o:p></o:p></p> <p style="padding: 0px;
