Abstract

A new way which can reduce environment noise underground in mine tunnel is produced. By analysis of the noise in central water pump house, point out that noise underground is mainly consist of base frequency and harmonic frequency coming from electric motor and transformer, with its frequency coverage below 650Hz. Acoustic spread environment in mine tunnel is similar to that in duct. Therefore, it is suitable to reduce noise by active noise control method. According to installation situation of equipment and noise distribution characters, feed forward FXLMS algorithm is used. Simulated results based on Matlab proved that there is an average of 13dB reduction using active noise control system.
