Charakteristiky NVH \u0161pir\u00e1lov\u00fdch prevodoviek s\u00fa hlavn\u00fdm faktorom pri v\u00fdvoji nov\u00fdch produktov hnacieho \u00fastrojenstva. NVH mo\u017eno kvantifikova\u0165 pomocou vlnovej anal\u00fdzy, r\u00e1dovej anal\u00fdzy a \u0161tatistickej energetickej anal\u00fdzy. Tieto techniky sa zvy\u010dajne pou\u017e\u00edvaj\u00fa vo frekven\u010dnej oblasti, ale mo\u017eno ich pou\u017ei\u0165 aj v oblasti re\u00e1lneho \u010dasu.
Najz\u00e1kladnej\u0161ia met\u00f3da NVH vyu\u017e\u00edva mod\u00e1lnu anal\u00fdzu na kvantifik\u00e1ciu prenosov\u00e9ho \u0161umu.

Jedn\u00fdm z najd\u00f4le\u017eitej\u0161\u00edch aspektov NVH je integrita sign\u00e1lov\u00e9ho re\u0165azca. Sign\u00e1lny re\u0165azec je ovplyvnen\u00fd n\u00e1razom ozuben\u00fdch kolies a buden\u00edm hlavnej skrine prevodovky. Prv\u00fdm krokom pri kvantifik\u00e1cii NVH je vytvorenie sign\u00e1lov\u00e9ho re\u0165azca. To je mo\u017en\u00e9 dosiahnu\u0165 porovnan\u00edm sign\u00e1lov, ktor\u00e9 s\u00fa zaznamenan\u00e9 na anal\u00f3govo-digit\u00e1lnom prevodn\u00edku alebo pevnom disku. Potom sa pomocou r\u00fdchlych Fourierov\u00fdch transform\u00e1ci\u00ed sign\u00e1ly preved\u00fa z \u010dasovej dom\u00e9ny do frekven\u010dnej dom\u00e9ny.
Pre anal\u00fdzu NVH je d\u00f4le\u017eit\u00e9 z\u00edska\u0165 reprezentat\u00edvny prototyp s\u00e9riov\u00e9ho vozidla. To je nevyhnutn\u00e9 u\u017e v ranej f\u00e1ze n\u00e1vrhu, preto\u017ee zmeny v kone\u010dnom produkte si \u010dasto vy\u017eaduj\u00fa podstatn\u00e9 \u00fapravy dizajnu.
Pri \u0161pir\u00e1lov\u00fdch prevodovk\u00e1ch je hlavnou v\u00fdhodou konfigur\u00e1cie s reverzn\u00fdm modulom to, \u017ee v\u00fdroba radi\u00e1lnej prevodovky je ekonomickej\u0161ia.
