Pink noise it's self will not cause damage to your hearing. However it is how loud and how long you play the sound for. If you listen to pink noise with a volume level under 85db SPL(Sound Pressure Level) is quite unlikely to cause any damage to your hearing, even if listening to it continuously =)
How much db noise produce pain to human?
Anything over 85db can cause hearing loss, and small firearms produce about 120db. Whether or not these produce pain depends on the individuals sensitivity. to sound. A rocket on launch pad produces around 180db on launch which causes irreversible damage. It is also important to note how the intensity of sound changes with its db level. Sound at 190db is 10 times more intense then 180db So a sound at 200db would be equal to 20 rocket launches.
