Metal Acoustic Barrier

metal acoustic barrier is a noise reduction measure with metal plates as the main body and sound-absorbing and sound-insulating materials installed inside. By physically blocking and converting sound energy, a sound shadow zone is established between the noise source and the sound reception point, achieving a noise reduction effect that attenuates the direct sound by 10~20 decibels.
