(EN) INTERFERENCE NOISE-CONTROL UNIT
(FR) UNITÉ DE COMMANDE DE BRUIT D'INTERFÉRENCE
Abstract
(EN)
The present inventive concept relates to an interference noise-control unit, for installation on a sound arresting wall for reducing noise from trains or cars. The interference noise-control unit comprises: a housing to be secured on a sound arresting wall. The housing comprises a hollow compartment comprising at least one first channel and at least one second channel, wherein the first channel has a first channel height A and a first channel length B, and wherein the second channel has a second channel height A' and a second channel length B', and wherein the first channel height A is different from the second channel height A'.
