Nonetheless, the sound level controls, noise mapping and noise abatement represent only a small part of the tools that can be used by the planner to fight noise pollution or a bad soundscape and get to a better environment.

A Positive example of good administration comes from the City of Brighton, UK that is actively collaborating with the University of Sheffield and the SONORUS network. The city of Brighton is considering the acoustic and soundscape as an integral part of the city and not as a secondary aspect. For example, the quality aspects of the soundscape have been investigated in the project of transformation made for the Valley Gardens in Brighton. The Valley Gardens are part of the city that presented high noise levels and those having a bad influence on the green areas present in the site. In the city of Brighton, Harry Witchel conducted an experiment that has strongly influenced the footprint of this work.

In this project I have collaborated with team members of the SONORUS network working on the path created by Harry Witchel in his study on the West Street Tunnel experiment (Witchel, et al. 2014).

The SONORUS network is a team of researchers from several different universities in Europe, including, Chalmers, Naples, Gent and Sheffield. Along with the universities there is the collaboration with various engineering consulting companies and city councils. The main test sites are: Brighton, Rome, Berlin and Antwerp. The aim of SONORUS is the planning of the acoustic environment of the cities that "supports wellbeing and health of the people living there" (SONORUS, 2013)

In this thesis is presented an empirical case that tries to demonstrate how is possible to impact the individuals' behaviour, by changing the characteristics of the soundscape. As for the West Street Tunnel experiment, where the subjects using the tunnel that connected West Street to the coast where find place all the venues of the nightlife of Brighton.

It has been decided to use three different music excerpts used in the West Street Tunnel Experiment and observe their effects on the subjects of the Concourse Bridge area within the University of Sheffield Campus. Thus observing how the subjects, unaware of being observed, responded to the three condition plus the "no music" conditions in terms of measurable variable recorded by video-camera. Then the data were collected from the recordings and inserted in a database that allowed running statistical tests on the sample.

The body of the work is divided into six chapters. The first three namely Chapter 2, Chapter 3 and Chapter 4, consist in a literature review. More precisely Chapter 2, reports some examples of the research that has been carried out in the field of soundscape structuring the literature review around the model created by Herranz-Pascual that stated that the soundscape research might be arranged around three major factors, as a matter of fact this part conducted us to place the research on the side of the activity, as it has resulted the least explored area. The Chapter 3 crosses the boundaries of the soundscape to quickly explore the field of market research that explores the effects of music on the clients' behaviour. In the Chapter 4, the West Street Tunnel experiment is exposed in more detail with the results obtained in the study. The Chapters 5,6,7 regard the Concourse Bridge Experiment that has been carried out and are respectively the sections containing the objectives, methods and results.

The final chapter include the discussion of the results obtained, according to the existing research and the future possible perspectives.

In the appendix A, is reported the full database extracted from the video recordings and in appendix-B is reported the preliminary design of the experiment with the preliminary
