•Exposure or repeated exposure for an extended period of time to music and other sounds that are too loud can cause damage to your hearing resulting in temporary or even permanent “noise induced hearing loss”.
•Symptoms of hearing loss increase gradually with prolonged exposure at high levels of loudness.
Initially, you may not even be aware of the loss unless detected with a hearing test.
