Resumen
Noise generation in modern vehicles cabin is mainly due to the contact among small mechanical parts integrated on systems such as steering angle sensors. Currently, to ensure that the noise produced by the steering angle sensors is below the limits, it is necessary to carry out tests in an anechoic environment. This work aims to compare the steering angle sensors produced by two different ways (normal line production in factory and 3D printer technology) using a PU probe with a particle velocity and pressure sensor, as well as a software for graphical noise display (Scan and Paint feature).
This method is shown to be less susceptible to the surrounding environment noise as compared to the conventional microphones and it can be used in the assembly line for noise assessment of steering angle sensors.
