For an in-car audio system, road noise is unavoidable—it will always be there. How do we solve this problem? Of course, many different methods have been tried for the solution. Some systems that were already in existence used the simple technique of automatically boosting the sound level when the car starts running or applying equalization to adjust the sound beforehand assuming that noise will be present.
However, these primitive functions are not commonly used now. Since our ears are very sensitive, there was a feeling of something being wrong. For example, when the car accelerates, the increase in volume is delayed slightly, and when the car stops, the level goes down very unnaturally. Or in the case of fixed equalization, the sound balance is unnatural since the frequency content of the noise is not considered.
To solve the effects of noise in the car cabin took nothing less than a revolution. It took more than ten years for Road EQ to become a reality, from the initial idea to the final installation in AlpineF#1Status. There is nothing more depressing for an engineer than to pour out their heart and soul into developing a technology and seeing customers not accept it. That’s why I’ve approached this problem with the idea of creating a function that once customers use it, they can’t get along without it. When I was a university student, I studied hearing aids, and researched how to make it easier to hear and distinguish sounds in difficult audio situations. In reality, this has been my life’s work. And that’s a primary reason why I embraced this challenge so wholeheartedly. |
