We know railway noise. With 18 years experience from one of the world top competence centers in the field of railway acoustics Akustikdoktorn Sweden has the competence needed to analyse your needs, and come up with adequate solutions.\u00a0Bombardier Transportation Global Centre of Competence for Acoustics and Vibration,\u00a0<\/span>ett av v\u00e4rldens fr\u00e4msta kompetenscentra inom omr\u00e5det, har Akustikdoktorn kunnandet och n\u00e4tverket f\u00f6r att analysera era behov och ta fram effektiva l\u00f6sningar.<\/span><\/p>

Infrastructure:<\/u>\u00a0\u00a0<\/u>We work out the most effective noise control scheme with respect to cost and other constraints; including barriers, grinding as well as rail- and wheel damping measures<\/span>.<\/i> Resultatet \u00e4r typiskt en kombination av skr\u00e4ddarsydda program f\u00f6r sp\u00e5rslipning respektive hjulsvarvning och sp\u00e5rn\u00e4ra installationer av tex Top of Rail sm\u00f6rjautomater<\/a>, bullerplank, diffraktorer samt hjul- och sp\u00e5rd\u00e4mpningssystem<\/span>.<\/i><\/p>

Vibrations:<\/u>\u00a0<\/u> We also measure and assess ground vibrations and design a balanced combination of isolation measures to be applied in the ground as well as in building structures<\/p>

Railcar design:<\/u>\u00a0 <\/i>Vi st\u00f6ttar med kravst\u00e4llning vid upphandling av j\u00e4rnv\u00e4gsfordon<\/a> samt akustisk planering och kontroll av bullriga komponenter som dieselmotorer, HVAC system, kompressorer, motorer samt aero-akustiska k\u00e4llor. Vi tar fram tekniska specifikationer gentemot underleverant\u00f6rer, definierar program f\u00f6r uppf\u00f6ljning och kontroll samt f\u00f6resl\u00e5r effektiva bullerreducerande \u00e5tg\u00e4rder. F\u00f6r korgkonstruktioner f\u00f6rdelar vi ljudkraven p\u00e5 olika delsystem och fungerar som en kunnig part i konstruktionsarbetet. Akustikdoktorn har gedigen erfarenhet av multidiciplin\u00e4r konstruktion med s\u00e5v\u00e4l strukturella lastkrav, ljudkrav, brandkrav och viktkrav. Vi har erfarenhet av viktminimering<\/a>\u00a0med avseende p\u00e5 last och ljudreduktion och vet hur man b\u00e4st drar nytta av d\u00e4mp- och absorptionssystem. Vi tar fram ljudbudgetar och ber\u00e4knar akustisk prestanda<\/a>. Vi analyserar PA system med h\u00e4nsyn till krav p\u00e5 taluppfattbarhet (RASTI, STIPA) b\u00e5de i fordon och p\u00e5 perrong. Dessutom har vi erfarenhet av att minimera buller fr\u00e5n elmotorer.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
