Abstract (en)
[origin: WO2020077382A1] The present invention relates to the field of sound attenuating, absorbing or reflecting panels, such as plastic or concrete panels, sound attenuation barriers or other wall structures. The present invention provides a mould with at least one protrusion configured to form at least one feature of the panel during production and provides an absorptive layer in a predetermined orientation relative to the protrusion. Panel material is added to the mould and then the panel is formed so as to retain the absorptive layer within at least a portion of the panel.
