INDOOR NOISE FROM URBAN RAILBOUND TRANSPORT
(2016)- Abstract
- Methods for determination of indoor noise and vibrations from urban rail bound transport are presented in this work. Both measurement methods and empirical prediction methods are described. The data and results are taken from field measurements of noise and vibrations from the trams and metro trains of Oslo.
The methods applied should be universally adaptable. The general approach is to use empirical modelling based on large measurement series and statistical
analysis. A complete model consists of a description of outdoor noise and vibrations as well as transmission through buildings and a correct determination of the physical and perceived immision. The introduction, chapter 1, gives a description of this type of model. This is...

Article 1 gives a description of measurements and building of an empirical model for outdoor noise from trams The difference in groundborne noise and vibrations from two types of
metro trains is described in article 2. The general principles of empirical modelling as applied to indoor noise and vibrations from trams and metros are described in chapter 3. Articles 3, 4 and 5 deal with different technical aspects of the measurement of transmission of airborne sound through building
facades.The concepts behind these measurements are discussed in chapter 4. Chapter 5 and article 6 discuss transmission of vibrations into residential buildings. Chapter 5 describes weighted physical vibration levels from several metro trains and includes preliminary results from investigations of perceived
annoyance from vibrations. Article 6 includes considerations of spectrum shapes and variation between individual train passages. Chapter 6 and article 7 are about field measurement of the noise and vibrations inside residences.
Chapter 7 presents the works that are planned in the near future to extend and complete the models presented. (Less)
