Development of impact noise reduction algorithm using active noise control

초록

In this study, the algorithm to reduce an impact noise was developed using an active noise con-trol (ANC). When the impact sound with a large magnitude in an instant was used in a conven-tional ANC, the convergence performance was degraded and it is not possible to ensure stability. The reference signal was accurately calculated using Prony’s method that was considered to damping coefficient of the impact noise. A floor noise generated by standard heavy impact source was re-duced at the error microphone.
