Can listening to loud music during an aerobics class damage my hearing?
You probably won’t permanently damage your hearing after just one session, but repeated noise exposure definitely can cause permanent hearing loss. If your ears are ringing and/or feel plugged after the session, you probably have a temporary hearing loss. You can visit the EAR FAQ site here for more detailed information. I also placed a link here (about 90kb’s to download). to a pdf document with his response.
