Now, blasting music period will damage your hearing. There are tiny hairs in your inner ear. Sound is vibrations and those hairs react to the vibrations to create the sounds you hear.
I don't understand how anyone can think the pain in their ears is nothing at all. It hurts my ears at church when I sit in the first 5 rows, close to the speakers. I sit in the back so my hearing isn't damaged. I don't want to be deaf before I'm 50.
Using earphones to listen to music does not damage out brains. However, it can damage our ears, especially when the volumes are not regulated well. There are many types of earphones that give off different quality sound and people should be careful when using them. Your eardrums can slowly be damaged and you should watch for early signs of deafness.
