Simultaneous measurement of the vibration levels of the hydraulic steering pump and its supports on the outside of the vehicle, and the sound pressure at various points both inside and outside. From this point on, diagnose the causes of noise transmission from source to receiver and propose the most optimal solutions.

In order to reduce the noise generated during the movement of one of the trailers by transporting cargo containers, the trailer noise is measured by moving at appropriate distances with both full and empty containers. Based on the results, the causes of the problem noise are determined and the correction is designed.

Assessment of the contributions of the different subsystems of the CH-150 model to the noise received in the driver’s position and at an external point, with the objective of determining the modifications necessary to the vehicle in order to reduce the sound pressure level received at these two points. Carrying out measurements with the vehicle stationary according to the TPA methodology to know how much noise comes directly from the holes and what part comes from the vibration of the structure.

Determination of the vibration power transmitted from the engine to the vehicle bodywork CH-150 of AUSA, through its different connection points. Evaluation of the power transmitted by the main motor-body connection points using the Mobility and Source Descriptor Method, allowing to find some solution that reduces the current vibration level.

Development of a computer application made in Matlab language, so that from the data supplied by the user can make calculations for the characterization of their gear changes and representation of the results obtained. Complete characterization of a gearshift system that allows to establish the necessary modifications to achieve the vibro-acoustic requirements that the client establishes for these mechanisms.

Measurement of sound pressure at different points and under controlled operating conditions of the Ferrari 456 model. Application of the methodology of Investing models in order to know the noise level of each of the surfaces of the cabin in order to be able to treat it and, at the same time, predict the improvement obtained with the modifications made.
