Continuous exposure to noise can generate a detrimental effect in health. However, it is considered as an inherent issue on industrial processes or even on commercial areas where heavy traffic and congestion are difficult to supervise. Hence, it has been tried to be reduced through passive mechanism, such as absorbing materials, which result to be ineffective cancelling low frequencies. Additionally, it could be unpractical when there are space limitations. In order to overcome these drawbacks, active control approaches have been developed in which a secondary sources array is required to cancel the main source by destructive interference. Due to the fact that a secondary source is expected to be equal in amplitude and opposite in phase, secondary sources need a particular control algorithm to achieve the desired superposition. In this work active noise control strategies are analysed, simulated and implemented. Furthermore, adaptive algorithm Least-Mean-Square is presented as the most convenient classic control strategies. For this purpose, Diesel and Electric motors under operating range from 200 to 3000 RPM (revolution per minute) are evaluated considering noise levels around 90 dB.
