  1. 1. The future noise mapping model in Sweden

    University essay from KTH/Teknisk akustik

    Author : Johanna Sturk; [2022]
    Keywords : Mechanics; Acoustics; Noise Emission; Noise Mapping Model; CNOSSOS; Nordisk beräkningsmodell; Mekanik; Akustik; Buller; Beräkningsmodell; CNOSSOS; Nordisk beräkningsmodell;

    Abstract : An extensive technological shift is currently taking place to mitigate climate changeand this trend is particularly noticeable in the transport sector. This is interestingfrom an acoustical perspective, since it changes the noise environment in society. READ MORE

  3. 2. Reflected Train Noise in Swedish Noise Prediction Methods, a comparison between measurements, Nordic Prediction Method, Nord2000 rail and CNOSSOS

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Ka Hou Karl Ho; [2020]
    Keywords : Nord2000; NMT; Noise prediction method; sound propagation model; source model for railway noise; reflected sound; Nord2000; nordiska beräkningsmodellen för tågbuller; bullerberäkningsmodell; Ljudutbredningen modellen for tåg buller; källsmodell för tåg buller; fasadreflektioner;

    Abstract : The Swedish law requires a set of noise limit for residential buildings for health and safety. Conventionally, the Nordic Prediction Method (NMT) is used to predict the noise. However Nord2000 and CNOSSOS is going to be introduced to replace NMT. READ MORE

  4. 3. On long-range and high frequency propagation alongparallel strip conductors in layered media : A simplified yet accurate method using the mode matching technique in the spectral domain

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Benjamin Oakes; [2013]
    Keywords : ;

    Abstract : Electrical arcing in the railway environment radiates wideband noise that can disturb nearbysensitive electronics e.g. signaling systems. High frequency disturbances follow conducting wiresand rails. READ MORE
