Abstract
As vehicles have evolved from simple to complex machines with specific configurations depending on their main role, the issue of interior noise has become a topic of interest. The present paper presents a model of experimental acoustic determinations made based on standardized acoustic emission factors for a vehicle in the N2G category, taking into account the volume of the vehicle, its speed, road configuration, and the distance from the receiver. Thus, significant conclusions are reached regarding the level of acoustic emissions in the vehicle cabin. Cumulative preliminary estimates were also made for the level of interior noise in the special purpose vehicle, monitored while stationary and in motion, in order to obtain an initial picture of the cumulative impact of noise and vibrations generated by acoustic sources originating from the operation of the vehicle. Noise tests were performed under realistic operating conditions during the intensive testing period.
