“…The Royal Decree 286/2006 [BOE, 2006] establishes regulations to protect the security and health risks of workers from noise exposure. Although this Royal Decree is usually applied in industries and companies with loud noise levels [Fernández et al, 2009], [Fernández et al, 2010b], [Fernández et al, 2010a], it is important to consider also the noise exposure of the workers driving to or from the work place, and also, professional drivers, taxi drivers, policemen, etc. It is important to know the noise sources of the car and their influence on the noise heard by the driver.…”

One of the most important noise causes in our cities is the traffic. The noise generated by the vehicles is not only due to the engine, but there are some other noise sources. Among them the tyre/road noise can be highlighted.Coherence and array based techniques have been used in some research to locate the noise causes and identify the main noise sources. Nevertheless, it is not usual in the literature to find the application of this kind of techniques in the car sector. This Thesis starts taking into account the possibility of using this kind of measurement techniques in cars, to demonstrate their feasability and their quality to evaluate the noise sources under two different conditions: when the car is stopped and when it is in movement.Selective Intensity was chosen as coherence technique, evaluating the coherence between the noise in the driver's ears and the intensity radiated in different points of the engine.Array based techniques carry out the best results to noise source location. Statistically Optimized Near-field Acoustical Holography (SONAH) is the measurement technique chosen for noise source location and characterization in the engine at low frequency. On the other hand, Beamforming is the technique chosen in the case of medium-high frequency and to characterize the noise sources when the car is in movement.The proposed techniques not only can be used in actual measurements, but also provide a lot of information and are very versatile to noise source characterization.
