      • Sound is POWERFUL
      • People tend to want more sound in order to feel it.
      • Listen to enrich
      • How loud is loud?
        • Sound is measured in decibels (dB)
          • Long term exposure to loudness = temporary/permanent hearing damage
          • Young people believe only people 50+ receive hearing damage.
          • Hearing loss is irreversible
      • How the ear works
        • Sound goes into ear canal and hits ear drum
        • Then vibrates bone within
        • Hair cells stimulated that leads to connection in the brain
        • Loss of hair cells = worse hearing
      • Hear what?
        • 10-15% loss = mild
        • 40-50% = moderate
        • 60-80% = severe damage
      • Signs of damage
        • Temporary threshold shift
          • “noise hangover”
        • Ring of the ears
          • Tenetis
            • perception of sound that is not actually real, but rather from hearing damage
        • Can’t hear high frequencies
        • Ear protection
          • Does not change fidelity of sound but rather volume (db)
          • Ear plugs can reduce sound by 30 db
          • Cotton and toilet paper does not work 🙂
          • Once you get used to wearing it, the sound overall becomes normal.
        • Do not get to close to speakers
          • 10 feet rule between one’s self and the speaker
        • Turn down volume
        • Take a break from loud sound
        • Avoid stimulants
          • Can amplify the effects of loud sound

          • Noise exposure in orchestra often exceed the safe levels of sound because of the enclosed environment.
        • Marching Bands
          • Marching band members are exposed to high levels of sound.
            • Percussionists are especially exposed high levels of sound that reach peak sound pressure.
          • Employers of marching bands have the duty of protecting their employees’ hearing.
