      abstract     = {This work aims to expand the understanding of sound
                      scattering in architectural spaces and the comprehension of
                      its influence on the auditory perception in concert halls.
                      The notion of scattering coefficient, which numerically
                      represents the physical phenomenon of sound scattering,
                      constitutes the main paradigm for the entire work. In a
                      first part, the scattering coefficient is presented in its
                      meaning and implications, providing both the mathematical
                      formulation and the empirical evaluation. Scattering
                      coefficients of new objects, such as pieces of furniture,
                      have been for the first time determined, hence the
                      foundations for a new scattering coefficient open database
                      is laid. A new solution for avoiding recurrent measurement
                      inaccuracies is presented by means of an improved
                      measurement setup, which consists of a revised scale model
                      reverberation chamber. The benefit of having more accurate
                      acoustic computer simulations by using a wider set of
                      experimental data for scattering coefficient is proved by a
                      case study of classroom acoustics. The implementation of
                      scattering coefficient in different room acoustic computer
                      software is shown and discussed by using a concert hall as a
                      case study. In a second part, the relationship between
                      scattering coefficient and auditory perception is explored.
                      Binaural impulse responses have been determined for three
                      different scenarios, such as two virtual enclosed spaces and
                      one real concert hall, and convolved with music samples to
                      be used in listening tests. Results from listening tests
                      show how changes in scattering coefficient of diffusing
                      surfaces affect the perception of music among the audience
                      in concert halls. A difference limen for scattering
                      coefficient is determined by means of auralized binaural
                      room impulse responses, which have been obtained under
                      different scattering conditions. Results from listening
                      tests are shown and discussed.},
