Vides zinātne autotransports frekvences attālums troksnis skaņas intensitāte

description

Bakalaura darba mērķis ir raksturot autotransporta radīto trokšņa frekvencionālo sadalījumu pilsētas vidē. Izpētīt autotransporta trokšņa līmeņa frekvencionālo novērtējuma mainību pilsētā pie dažāda vieda plūsmas dinamikas, kustības ātruma, ātruma paātrinājuma un palēninājuma. Apskatīt, kā troksnis mainās pie noteiktiem attālumiem un diennakts periodiem. Pētījums veikts intensīvā ceļa satiksmes posmā, Jūrmalas pilsētā, autoceļa posmā - Lienes iela. Izvēlētā pilot teritorija ir viena no Latvijas tūrisma iecienītākajām vietām, kuras teritorijā noteiktos gada laika periodos būtiski palielinās transporta plūsma. Nozīmīgākais trokšņa avots ir vieglās automašīnas. Mērījumi tika veikti izmantojot viedtālruņa palīdzību ierakstot satiksme skaņu. Iegūtie dati tika apstrādāti ar specifisku “Audacity”, lai detalizētāk analizētu frekvencionālo sadalījumu, dažādu frekvenču dominanci un izplatību.
