Loud music, whether it comes from radios, headphones or at the disco, could severely impair one's hearing. A study done in a general hospital has warned that prolonged exposure to loud music could damage the eardrums. When exposed for several hours to 120db- A (the intensity of sound measured at a disco), permanent hearing loss might result.
In a earlier UP-PGH study on noise-included hearing damage, a team of
doctors had themselves exposed to the music at a disco. Prior to the exposure, their hearing was tested and recorded as normal. After one hour at the disco where the sound intensity was measured at 120db A, they were again tested and “temporary shift in the hearing impairement for a day or two. After a couple of days, their hearing was back to normal.
For those who seem to be permanently attached to their headphones, the research cautioned to keep the volume down. “When the volume is constantly set at full blast for long durations, and directed right it can do damage inside the ears- the listener may permanently lose his hearing.
