Highway sound barriers
Highway sound barrier, also known as noise wall, sound-absorbing barrier, anechoic shutters, is a sound-absorbing material for the core material, the use of colour steel sandwich panel acoustic components assembled into the absorption, acoustic isolation barrier. Colour steel sound barrier sound-absorbing acoustic components can be processed into several kinds of sound-absorbing and sound-insulating acoustic units such as louvered, perforated, micro-perforated and slotted holes. Shutters and perforated sound-absorbing colour steel composite panels have better sound insulation performance in medium and high frequencies, and colour steel composite panel acoustic components without slotted holes have better sound insulation performance in medium and low frequencies. Therefore, different structural forms of sound barrier can be selected according to the noise characteristics.
