Quiet vehicle development, the reduction of traffic speed and density (e.g. at night-time), the construction of new roads away from residential areas and the installation of anti-noise barriers (roads, railways, industry) have positive effects on the reduction of the average level of noise pollution.
Razvoj manj hrupnih prometnih sredstev, omejevanje hitrosti vožnje in gostote prometa (npr. v nočnem času), gradnja novih prometnic, odmaknjenih od bivališč, namestitev protihrupne zaščite na hrupne objekte (ceste, železnice, industrija), ugodno vplivajo na zmanjševanje povprečne obremenitve s hrupom.
