To avoid hearing loss, please set the playing equipment volume to minimum before 
connecting  the headphone (or earphone). After wearing the headphone (or earphone), 
increase the volume to a proper level. The noise is calculated by dB. The noise above 85 dB 
leads to hearing loss. 
Please pay attention to your operation habit. The relationship of  volume & hearing time 
and hearing loss as below: the higher the volume is, the shorter the hearing time should be. 
The more proper the volume level is, the longer the hearing time  can be. The long time 
hearing at high volume level leads to permanent hearing loss.
This dB table lists the comparison of some normal sounds and the potential hurt level to 
your  hearing.
