Honking car horns, DJ sound & religious practice of using loudspeakers is order of the day in India. The Supreme court has already set time & decibel limits on the usage of loudspeakers. In any condition, One can not exceed more than 55 dB noise level. But challenge in India is Law- enforcement & common man's limited knowledge about side effects of high noise level. It is known fact that once continuous exposure to noise level more than 55 dB is one of the reason of heart attack.
To soundproof any window , 3 things to consider

- Present window sash/frame ( Vinyl i.e. uPVC/ OR, Aluminium/ OR, Wood) must be completely air tight as well as it should have noise reduction min. 30 dB.
- Glass- If it is single glazed, Sound proofing is not possible. Double glazing with lamination is must. You can check on the following interesting app by Saint Gobain Glass - Glass dBstation-what difference different glasses will make in reduction of barking dog noise.
