Use of Automated Methods for ESE Drive File Convergence

As vehicle cabin sealing and sound deadening efficiency improve, annoyance sound levels from sources such as wind and tire noise are mitigated. Unfortunately, natural engine noises that are critical to driver and passenger visceral experience are also blocked. In order to deliver desired feedback from the engine, we compensate through sound tubes to the engine bay or ESE. ESE has proven to be the more refined and effective method of achieving the desired interior cabin sound quality but the tuning process is exhaustive. Current technologies require that each vehicle configuration (architecture, trim level, etc.) demand manual, iterative tuning loops which is time and energy intensive. Proposed is a method to automatically complete the iterative tuning process and converge to a desired sound profile. This process has proven to cut time spent tuning by 75% and is beneficial over manual tuning because it delivers a final calibration that meets concrete, objective targets rather than subjective evaluator decisions.
