  1. 1. Epidemiological survey of moderators moderators for railway noise annoyance

    Master-uppsats, KTH/Teknisk akustik

    Författare :Tagiadin Assenai; [2023]
    Nyckelord :Akustik; psykoakusti; bullerstörningar; järnväg; ljudstörningar;

    Sammanfattning : The disturbance caused by railway noise has been investigated in this paper. A total of 127residents living near the Västra Stambanan were interviewed, and the noise levels from NordiskaBeräkningsmodellen were compared with the perceived disturbance. The results of the studyindicate a correlation between indoor noise levels and disturbance. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Sammanfattning : 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.

    Nyckelord :;

    Sammanfattning : Bridges are one of the most important structures in our infrastructural system today.The modern society depends on these structures which in majority are nearingthe end of their design life. Therefore, the need for monitoring of bridges is increasing. LÄS MER

  5. 4. The future noise mapping model in Sweden

    Master-uppsats, KTH/Teknisk akustik
