How Loud Is Too Loud: Decibel levels of common sounds
Decibels are in essence a measure of volume
The volume or intensity of sound is measured in units called decibels (dB), generally on a scale from zero to 140 (any higher than 140 and you are in trouble immediately). The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss. Hearing loss can occur with regular exposure to noise levels of 110 decibels or more for periods longer than one minute.
So How loud is too loud?
The risk of sound damaging your hearing is in fact based on how loud and for how long. Continued exposure to noise at or above 80-85dB over time can cause hearing loss, however, the exposure length in that case would be hours. Generally speaking, if you have ringing in your ear or your hearing seems dull after you have been exposed to sound (including loud music) or noise you have exposed yourself too much. However, it is important for me to point out that you may still be damaging your hearing even if you don’t have these symptoms.
If loud music ever feels way too loud or causes pain in your ears, leave the room or turn it down immediately. Without noise measuring equipment it is impossible to tell what noise level you are being exposed to. So, a handy rule of thumb is that if you can’t talk to someone two metres away without shouting, the noise level could be damaging. Speaking of noise measuring equipment, you can download plenty of sound measuring apps for your Android or Apple smartphone. Download one and use it to understand the sound around you.

Long Term Exposure To Noise Over 85 dB Can Cause Hearing Loss
No more than 15 minutes of unprotected exposure to 100 decibels is recommended. Long-term exposure to 80-85 decibels or over can cause hearing loss. Protect your hearing, because once the damage is done, it is done. It is important that you realise that the noise we speak of is any sound, it isn't just what you think is noise. Music presented at the right dB level will do just as much damage to your hearing. Once you go past 85dB, you are on the clock.
Don't forget, sound is sound, at the right volume level that music you love will damage your hearing
