It is also important to consider the volume. So, if adults can perceive noise at a volume of 85 dB for 8 hours without harm to their hearing, then the time for children is reduced. In general, experts recommend setting the volume level for a child in the region of 60-70 percent.
As for the actual children’s headphones, they must be chosen with care. So, according to a study by a clinic at the University of Colorado, almost half of the models selected by scientists were not suitable for children due to poor performance of the 85 dB volume limit: somewhere this level even reached 100-105 dB.
