Do you use earplugs?

I thought this would be interesting to know. Heres some info:
On the decibel scale the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB.
An increase of only a few decibels has a dramatic effect on the danger to hearing – this is because each increase of 3 dB(A) represents a doubling of sound energy (and halves the time you should listen for). As an example, being on a dance floor for one hour at 100 dB(A) delivers the same amount of noise energy to the ear (and therefore potential damage) as being on a slightly less noisy dance floor at 97 dB(A) for two hours. There is a big difference in the length of time you can listen for if you turn the volume down.
20 dB(A) is a quiet room at night
60 dB(A) is ordinary conversation
70 dB(A) is a city street
80 -110 dB(A) is a night club
110dB(A) is a pneumatic drill nearby
110 - 120 dB(A) is a rock concert
130 dB(A) is an aeroplane taking off 100 metres away
140 db(A) is a the threshold of pain for many people
Sounds over 80dB can damage your hearing. By law if your workplace has noise over 85 its required to tell you and provided earplugs i think. Earbuds can reduce the noise, you can a pair for £10-15 that reduce noise by 10-20dB across the board.

I use ER20s (reduce sound by 20dBs)
....what?
