High levels of noise are common in industrial settings, can act as a barrier to effective communication, cause loss of productivity, and in some cases be a safety hazard. Barriers and dampers are some of the typical passive control measure means. which however are unable to control low frequency sounds. The noise cancellation concept presented in this project employs active noise control principles through the use of an innovative industrial acoustic mitigation system ready for real time applications. The system uses microphones placed within the enclosing walls, process Digital signal processing (DSP) signals with a microcontroller and uses loudspeakers to produce anti-noise. Noise controlling active systems designs by embedded signal processing techniques has been the focus of interest of many designing and simulations. Among DSP methods, the system is capable of cancelling undesirable industrial noise over a given frequency range making the workplace healthier and safer by creative advanced selfish noise control techniques. The expertise of this technique is the real-time change and inexpensive module arrangement of materials which can be bought from the market easily. This project proposes a practical answer for those industries which are in need of efficient and flexible noise reduction techniques which also can easily be scaled. In conclusion, industrial practical operation noise control has advanced quite appreciably with the introduction and levels of use of this real time acoustic mitigation systems. Its applicability and effectiveness are useful in promoting health and safety in work settings where noise pollution is present.
