  1. 1. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Soraya Hosseinvash Azari; [2023]
    Keywords : Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

    Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE

  3. 2. Road traffic noise simulations based on 3D city models

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Wenjing Liu; [2023]
    Keywords : 3D city model; 3CIM; CNOSSOS-EU; noise simulation; city noise evaluation; data tailor; FME; SoundPLAN; Geomatics; Earth and Environmental Sciences;

    Abstract : Urban development and densification cause noise problems that can have a negative impact on human health. In 2002, the European Union (EU) stated the European Noise Directive (END) with the purpose to evaluate environmental noise levels (including the sources road, railway, and air traffic) in the member states every 5 years.

  4. 3. 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

  5. 4. Computational sound propagation models: An analysis of the models Nord2000, CONCAWE, and ISO 9613-2 for sound propagation from a wind farm

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jôse Lorena Guimarães da Silva; [2017]
    Keywords : Nord2000; CONCAWE; ISO 9613-2; noise propagation; noise wind turbines.;

    Abstract : The recent goals from some countries to become renewable energy based and reduce carbon dioxide emissions have caused the wind industry to grow. Together, the size of the wind farms and the noise emission have grown, while the noise emission regulations have to be fulfilled. READ MORE

  6. 5. Prediction of Sound Propagation From Power Transmission Plant

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Sun Jingchao; [2013]
    Keywords : ;

    Abstract : In ABB, Soundplan is the usually used software to predict the industrial noise for power transmission plants. However, the sound sources in Soundplan are modeled as point sources between which there are no sound reflections. For the real situation, the sound sources are very big and can be regarded as noise barriers. READ MORE
