| Abstract(in English) | In recent years, smart devices with integrated microphones, which are similar to earphones called hearable devices, have become widespread. It can be connected to a smartphone via Bluetooth, and in the future it is possible to connect to a vehicle and drive while wearing it. Therefore, we verify the possibility of reducing road noise by introducing an Active Noise Control (ANC) system into the hearable device. Since road noise is unsteady noise, a feedforward type control method is suitable, but due to its shape, it is necessary to reduce the distance between the reference microphone and the error microphone. However, noise reduction may be degraded due to the effects of causality constraints. As a method for improving this problem, a feedforward ANC system using FPGA capable of high-speed calculation has been proposed. Therefore, in this paper, we construct a head-mounted ANC system using this system and examine its effectiveness using an actual environment. |
