It depends also on the time of hearing.
"Permitted Noise Exposure Time Guidelines - SPL"
Sound pressure level Lp and permissible exposure time t:
115 dB = 0.46875 minutes (~30 sec)
112 dB = 0.9375 minutes (~1 min)
109 dB = 1.875 minutes (< 2 min)
106 dB = 3.75 minutes (< 4 min)
103 dB = 7.5 minutes
100 dB = 15 minutes
97 dB = 30 minutes
94 dB = 1 hour
91 dB = 2 hours
88 dB = 4 hours
85 dB = 8 hours
82 dB = 16 hours
Lower dBs are said to be harmless.
There is a Decibel Comparison Chart which states as follows
Weakest sound heard 0db
Whisper 30db
normal conversation 60 - 70db
Telephone dial tone 80db
city traffic, inside car 85db
train whistle at 500ft 90db
Subway train 200ft 95db
sustained expsure may
result in hearing loss 90 - 95db
Pain 125db
short exposure
permanent damage 140db
loudest sound possible 194db
permissable noise level exposure ranges from 90db per 8 hour day to 115db for a max exposure of 15 minutes per day
It depend on the person and on the time you are listening. Even 85 decibels are enough when you listen for a long time.
An impulse noise that's 120 db or higher can cause immediate damage. Things that produce sounds of that level would be gunfire, fireworks, or an explosion. I think I read somewhere that the loudest noise that the ear can hear is 194 db, which would cause a huge amount of damage to the ear, but I don't know if that would cause complete deafness. The only things that can possibly produce sound like that would be a rocket taking off or a sonic boom. Death of hearing tissue is at 180 decibels

What does 60 decibels sound like?
Go through the chart at the link below. Scan the whole chart; some levels are described more than once. Normal conversation is about 60 decibels, and ordinary piano practice is between 60 and 70 decibels.
How can cochlea be damaged by loud sounds?
Yes. Sound is measured by decibels. It is safe to only hear 65 decibels or less. If sound is higher than 65 decibels, it can 95.6% damage your eardrums. Listening to music through your headphones at highest volume from an mp3 or an iPhone is considered 82 decibels. Listening to a concert is considered 167 decibels. A blue whale is 300+. :)
How many decibels of sound does a subway train generate?
It generates 95 decibels at 200 feet. See the decibel comparison chart in the related link for further information.

Interaction of aminoglycosides and loop diuretics?
Using loop diuretics (such as furosemide) and aminoglycoside antibiotics (such as gentamicin, tobramycin) together can increase the risk of damage to the inner ear leading to hearing loss.Open in Google Docs ViewerOpen link in new tabOpen link in new windowOpen link in new incognito windowDownload fileCopy link addressEdit PDF File on PDFescape.com
Which is louder 60 or 70 decibels?
40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).
Why do workmen who uses drills suffer hearing loss?
Hearing loss can be caused by any number of things. Individuals who use loud equipment, including power tools, for a living have a higher propensity for hearing loss. This is because exposure to loud noise, especially for a prolonged period of time, can damage cells in the hearing organ (cochlea) that are responsible for hearing. Unfortunately, this type of hearing loss is permanent and irreversible. Therefore, it is important to always use hearing protections (ear muffs, or ear plugs) when around loud noise.For more information on Noise Induced Hearing Loss (NIHL) see the related link for an article by the Center for Disease Control.

Does it cause your environment damage?
I'll provide a link, but no, it causes very little environmental damage.
How can dancing affect hearing ability?
The link between dancing and the auditory system has been examined in detail throughout the works of the famous Dr. Ginbelek. According to this eminent practitioner, dancing can be prescribed as an alternative to inner-ear surgery as it's endorphin-releasing exercise has been known to loosen the ear muscle known as the "ear oblongulator", in charge of widening (or inversely narrowing) the inner-ear canal. Furthermore, research has shown a correlation between dancing in a confined area prone to high-volume music sometimes referred to as a "discotheque" and hearing impediments. Conclusive proof of the link between dancing and hearing.
