The shifted noise structure of the electric vehicle brings an option to add new noises. This opens an opportunity to create new and pleasant driving experience for your customers. From this perspective, sound quality engineering is the key tool to develop high-performing sounds within the vehicle. This technology is currently gaining ground in many industries.
It all starts with the acquisition of realistic sound data, including for instance binaural recording. Secondly, to be able to analyze the acquired sounds, you can proceed with audio replay, using different filtering and analysis through different sound quality metrics. And finally, you shall organize a Jury testing, which is based on subjective audio perception. Sound quality engineering combines objective analysis metrics with subjective analysis. This strategy will provide you with detailed insights to find answers to questions like – what do the customers like to hear? What sounds do they prefer in different corners of the world?
Another application, where sound quality is currently gaining importance, is the exterior artificial sounds generated by the acoustic vehicle alerting system (AVAS). This system warns pedestrians of an approaching vehicle. Developing new exterior warning sounds is something of a novelty. Different countries around the globe currently impose new certification requirements for electrical cars. Car producers need to design and certify warning sounds that the electrical cars must exceed traveling at low speeds. And at the same time, automotive OEMs are highly concerned about the perception of the new vehicle sounds. Designing new artificial sounds that reflect the brand DNA requires the right toolset for sound quality engineering.
