Does listening to a square dance subwoofer affect the hearing of a one year old child? How long should I stop listening? How many decibels of sound does not affect a one-year-old child?

The impact is very large, the baby listening to music is good, but their body functions are still developing, if the stimulus is too large, it will cause damage to them, it is best to listen to light music, and the volume should not be too large. To 1-year-old baby to listen to audio equipment playing out of the music time should not be too long, about 15 minutes a day can be. The optimal volume range is 40 to 60 decibels.
