LISTENING TO MUSIC REDUCES PAIN IN MICE, AND POSSIBLY HUMANS...

As far back as the 1960s dentists documented an apparent analgesic.

i.e., pain relieving, effect in patients who were exposed to noise during and after medical procedures

but the underlying mechanisms were unclear.

That makes a certain amount of sense even without a scientific explanation.

Sounds, particularly those of entertaining music, serve to distract people

from whatever else is going on around them and that might be enough on its own to relieve pain.

research from scientists at the Department of Anesthesiology and Pain Medicine and the University of Science and Technology

 of China appears to confirm that noise has a physical effect on pain signals

in the brain which extends beyond simple distraction. Their findings were published in the journal Science.
