Transport noise is detrimental to the comfort of passengers on the one hand, and to the peace and quiet of the population on the other hand, either outside (or in the environment) or inside buildings.

As far as public perception of transport noise is concerned, a distinction must be made between intermittent noise from passing trains, taking off or approaching aircraft and almost continuous noise along a busy street or motorway.

In a poorly insulated building, where the apartments are adjacent, the noise emitted by traffic disrupts the activity of the inhabitants and interferes with their sleep. Moreover, if there is a vibratory source located in one of the apartments, the sound waves resulting from its vibration will propagate by solid state to the hearing of the inhabitants.

If the vibration is high, it can be felt throughout their entire body. Similarly, noise generated by an acoustic source (equipment) located in that building can not only impact speech intelligibility, but also affect the quality of the sound heard and the quietness.

Artificial intelligence (AI) appears as a science whose goal is to enable a machine to perform tasks that humans perform with their intelligence.  Its use is the ultimate alternative that will allow industries to predict the lifetime of equipment and ensure the efficient operation of its sub-assemblies. In the future, AI will be able to contribute to the detection of the causes of vibrations or abnormal sounds on a vehicle or equipment.

Health effects of noise are the effects that sounds (audible or inaudible) can have (in the short, medium or long term) on health (directly or indirectly). They are the consequence of more or less regular, suffered or deliberate exposure to repetitive or quasi-continuous noise generated by various mobile, static and natural sound sources.
