Two years ago, a study said that the honking of automobiles on the road was a bigger noise polluter than the bursting of firecrackers with decibel levels touching 100 dB, as compared to the sound of the latter which hovered around 90 dB. Two-wheelers were among the biggest culprits, on account of the volume of such vehicles. The damage that constant exposure to vehicular noise inflicts is staggering. If the noise is within the range of 80-90 dB, it can damage the ears within eight hours. For sound levels exceeding 100 dB, listeners can get affected in under six hours, experts had revealed. Apart from irreversible hearing loss, it can trigger elevated stress levels, high blood pressure, heart disease, irritability, anxiety attacks, disrupted sleep patterns and more.
