Development of Active Noise Control System for Engine Booming Noise

Article of Honda R&D Technical Review Vol.15 No.2

Summary

Active noise control technology for booming noise has an issue in a balance between cost and performance, because it needs expensive high-performance processor as DSP for the purpose of many convolution operations. As a result, there are few applications of this type of technology to reduce booming noise.
The purpose of this paper is to propose a new algorithm significantly reducing the amount of arithmetic operations by focusing on the fact that booming noise is a narrow band noise. This algorithm enables us to employing inexpensive controller although adaptive signal processing is utilized. Also, the integration of this system with an audio system further improves the balance of cost and performance.
The system developed in this study has been applied in combination with an active control engine mount system to reduce booming noise generated in three-cylinder operation by a new model vehicle fitted with a new V6 engine provided with cylinder on demand, resulting in the achievement of excellent fuel economy and NV performance.
