BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Generally, high-volume undesirable sound is referred as noise pollution. During social celebrations, festivals, wedding ceremony, traffic etc high volume of noise is common and which is dangerous for the audio system of human beings. As per the guideline of Central Pollution Control Board (CPCB) of India, if the level of the ambient noise is greater than 50 dB continuously (especially silence zones), it can cause several health problems among the humans such as hearing loss, headache, high blood pressure etc. Therefore, something can be done to prevent our health from the undesired noise. People has to bear such noises against their will since they have no such option to avoid such inconvenience. There is noise cancellation earphone available in the market, but there appear to be no such device that can save user from unnecessary ambient noises.
[0004] There is, therefore, a need of a such device that can solve the above discussed problem.
