The regulations regarding the ventilation of environments underline the importance of guaranteeing not only adequate air exchange, but also maximum acoustic comfort inside homes. In urban areas, it is sometimes difficult to ventilate spaces through ventilation holes without being disturbed by city noise and traffic. For this reason, it becomes essential to use accessories that allow both regulated air exchange and the reduction of external noise. The vast range of silencers and acoustic reducers under the La Ventilazione brand responds effectively to this need, combining the functionality of the ventilation grill with a sound-absorbing system in a single device, promoting the natural exchange of air through the ventilation holes present in the facades of buildings and avoiding the propagation of noise.
