隔音屏(墙)的隔音效果才让汽车驾驶变得安逸

噪音被视为现代社会的三大公害之一,它能破坏人体神经,使血管痉挛,加速毛细胞的新陈代谢,从而加快衰老期的到来。而车辆在街道或高速道路中行驶时,无论周围环境抑或车辆本身都会不可避免的带来大量噪音,虽然它不足以令人致命,但是通常对会对车内人员造成影响,使人情绪变差,烦躁不安,尤其是对驾乘者来说,直接影响到其驾车过程中的安全性!

隔音墙

隔音墙(声屏障)主要用于高速公路、高架复合道路、城市轻轨地铁等交通市政设施中的隔声降噪、控制交通噪声对附近城市区域的影响,也可用于工厂和其它噪声源的隔声降噪。分为纯隔声的反射型声屏障,和吸声与隔声相结合的复合型声屏障,后者是更为有效的隔声做出来的。大多数的声屏障都选用吸声和隔声混合型的产品,该型产品的特点是对道路噪声的产生和传递特征有针对性地控制。如汽车与道路摩擦声或机车与轨道摩擦声在道路下部,声音有通过屏体上部绕射的特征,所以在设计上采用上下吸声,中间隔声的结构,这样可以有效地减弱噪声的绕射;声屏障的中间使用透明的反射型隔声板,能有效地中断声波的传播途径;同时也为司机和居民提供一个开阔的视野环境。建筑声学领域,通过声学治理,控制混响时间及室内声环境,满足专业场馆要求。根据声屏障应用环境,声屏障分为交通隔音屏障、设备噪音衰减隔音屏障、工业厂界隔音屏障。按材质分类又可以分为以下几类:金属声屏障(金属百叶、金属筛网孔)、混凝土声屏障(轻质混凝土、高强混凝土)、PC声屏障、玻璃钢声屏障等。按不同的用途又可以分为这样几类:铁路声屏障、公路声屏障、城市景观声屏障、居民区降噪声屏障等。
(Sound barrier (sound barrier) is mainly used in highway, elevated composite roads, urban light rail subway and other traffic and municipal facilities to reduce noise, control the impact of traffic noise on nearby urban areas, but also can be used in factories and other sources of noise insulation noise reduction. It is divided into pure sound insulation reflective sound barrier, and sound absorption and sound insulation combined with composite sound barrier, the latter is more effective sound insulation. Most of the noise barriers are made up of a mixture of sound absorption and sound insulation, which is characterized by targeted control of road noise generation and transmission characteristics. For example, the friction sound between the car and the road or the friction sound between the locomotive and the track in the lower part of the road, the sound has the characteristics of diffraction through the upper part of the screen, so the upper and lower sound absorption, the middle sound insulation structure is used in the design, which can effectively reduce the noise diffraction; the sound barrier in the middle of the use of transparent reflective sound insulation board, can effectively interrupt The transmission of sound waves also provides a wide field of vision for drivers and residents. In the field of architectural acoustics, reverberation time and indoor acoustic environment are controlled by acoustic treatment to meet the requirements of professional venues. According to the application environment of the noise barrier, the noise barrier is divided into traffic noise barrier, equipment noise attenuation noise barrier, industrial boundary noise barrier. According to the material classification can be divided into the following categories: metal sound barrier (metal louver, metal screen mesh), concrete sound barrier (light concrete, high strength concrete), PC sound barrier, glass fiber reinforced plastic sound barrier. According to different uses, it can be divided into several categories: railway noise barrier, highway noise barrier, urban landscape noise barrier, residential noise barrier and so on.)
 
当然除了公路行驶进行隔音墙降低隔音,车体本身也可以进行隔音处理,对车身进行隔音,可以提高车辆的舒适性。尤其是对音响有更高要求的车主来说,隔音更显得尤为重要,汽车行驶过程中,风噪,路噪,胎噪以及机件共振等带来的噪音严重影响车内音响的表现,安博士在消除震动杂音的同时,能够使立体音响达到最佳的发挥效果!
