The intensity of sound below 70 decibels (dB) - such as ringing phones, everyday conversation, the noise in the restaurant, do not pose the risk of hearing impairment (regardless of duration of hearing). Anything louder than 85 dB-like sound of the motor, workshop tools, lawn mowers, can eventually cause loss of hearing.

As for the intensity of the resulting sound through earphones can reach 87-100 dB, and when I hear the voice on the intensity for 8 hours per day can increase the risk of hearing loss significantly.
