A normal car releases around 85 dB of noise and a bike releases around 90 dB of noise. India is already the second most populous country in the world and a lot of people own either a four-wheeler or a two-wheeler vehicle or both. Traffic Noise- Except for the new generations of electric cars and bikes almost all the vehicles release a high amount of noise. Noise pollution is a consequential event so noise pollution definitely has a source and we will be looking further into the sources of noise pollution. Noise pollution is generally a by-product of action. So to get a clear reference on the decibel scale we can look into a few examples:ΔΆ0 to 25 dB is a whisper, 30 dB is noise at a quiet home, 60 dB is a normal conversation and 80 dB is the level of noise where it becomes physically uncomfortable for people. The system of the physical unit or the SI unit for measurement of noise is decibel (dB). Noise is non-harmonious and but even music played loudly can also become noise. Noise can be defined as unwanted or undesired sound.
