Many companies that have technological catch-up strategies have standardized and quantified the information and know-how accumulated at the imitation phase. However, excessive regulation has a negative impact on qualitative growth. Initial operation sound is the start noise of the car’s power seat, and developers are highly skeptical about the regulation. This study investigated the management status, influence factors, measurement levels, improvement methods, and degree of awareness. In conclusion, soft starters and limit switches are the most effective way to improve initial operation sound. The survey showed that only 37% perceived the difference when 30 people heard product with 10㏈ difference in the initial operation sound.
