Describe a time when you faced a challenge in optimizing the acoustic and vibrational performance of automotive vehicles. How did you overcome this challenge?

In my previous role as an Automotive NVH Engineer, I faced a challenge in optimizing the acoustic and vibrational performance of a new model of electric vehicles. The main issue was excessive noise and vibration in the cabin, which affected the overall comfort of the vehicle. To overcome this challenge, I conducted extensive testing and analysis using NVH simulation software such as LMS Test.Lab. I identified the sources of noise and vibration, which were mainly attributed to the electric powertrain and suspension system. I worked closely with the design and development teams to implement several solutions, including adding additional insulation materials, fine-tuning the suspension components, and improving the sealing of the cabin. Through iterative testing and optimization, we were able to significantly reduce noise and vibration levels, resulting in a much quieter and smoother driving experience for the customers.
