The right answer is 120dB.
The decibel (dB) is a dimensionless unit of magnitude used in telecommunications, electronics and acoustics.

Generally, the maximum advised dB for sound equipment is 90dB (you can see it in "safe" earphones). if you lessen to sounds higher than 90 dB for a long time, it could be hurtful for your ears.
