Original abstract

Vehicle noise is very actual topic today because there are very strict regulations given by EU. Noise on vehicle is produced by different subsystems of the vehicle and goal is optimize each of them to reduce overall acoustic emission. Locating noise sources of each subsystem is very important, because it helps to understand acoustic behavior of structure. Noise source localization can help in future research and development. Furthermore is really important to be able to locate noise sources with reliable and precise method. Acoustic Camera is one of the modern methods how to locate noise sources, the main idea is see what you hear. This article is about Acoustic camera application on the real noise location problems in automotive industry.

Czech abstract

Hluk vozidel je v součastnosti velmi aktuálním tématem, protože jsou zde přísmá legislativní omezení daná Evropskou Unií. Hluk vozidla je vytvářen různými konstrukčními podskupinami vozidla a cílem je upravit je tak, aby došlo ke snížení celkové hlučnosti vozidla. Lokalizace zdrojů hluku v jednotlivých subsystémech je velmi důležitá, neboť nám umožňuje lépe popsat akustické chování struktury. Použití akustické kamery je jednou z moderních možností jak lokalizovat a zobrazit zdroje hluku. Tento článek se zabývá aplikací akustické kamery na reálné problémy v automobilovém průmyslu.
