Acoustic screen dimmer, for transformer electricity located in buildings, characterized by a screen consist facing the inlet duct and ventilation air leaving a perimetral hole to flow. All lines are lined by acoustic absorbing. In such fader acoustic screen incorporated address changes or bends which together with the absorbent material, attenuates the noise caused by ventilation processing centers. Design and sections lines are designed so that noise transmitted abroad without reducing the air flow is reduced. (Machine-translation by Google Translate, not legally binding)
