Operation BANG

Handouts for students/parents

Dear Parents,

A guest speaker came to your child’s classroom today and spoke to the students about the prevention of hearing loss caused by exposure to excessive noise. For your reference, it is well documented that the incidence of noise-induced hearing loss in children is dramatically increasing (Montgomery and Fujikawa, 1992). This same study further indicated that by the time the students had reached the eighth grade the incidence of hearing loss had more than TRIPLED in a ten-year period.

The Students Learned:

Everyday examples of excessive noise exposure include:

  • The loudness level at an average rock concert is 120 dB. At this level, the unprotected ear may sustain some degree of permanent hearing loss after only 10 minutes of exposure.
  • On average, the user of a stereo headset sets the volume level at 100 dB. This is the equivalent loudness level of a chainsaw – which can diminish the ability to hear after only two hours.
  • A monster truck or tractor pull event easily reaches a loudness level of 110 dB and can damage hearing ability after no more than 30 minutes.
  • Many retrofit car stereos reach a loudness level of 150 dB – more intense than most gunfire – and may cause a measure of instant, permanent hearing loss.

The Students Learned:

Protecting oneself from a noise-induced hearing loss does not mean that you take away all the fun. Rather, it is a matter of developing behavior patterns that protect your hearing so you can continue to fully enjoy the activities. In today’s instruction, the students learned three ways to protect their hearing:

  • Turn down the volume
  • Walk away from the noise
  • Use earplugs or earmuffs

The Students Learned:

There is a simple test to determine that the volume of a stereo headset is at a safe level. If the child/user of the stereo headset can understand what is being said when a person talks to him/her standing at arm’s length, then the volume is probably at a safe level.

As a parent, there is no substitute for your awareness and good example. Turn down the volume. Avoid loud noise. Use hearing protection when mowing the lawn or using power tools. Your child can be one who reaches adulthood with a good ability to hear!

There is no cure for noise-induced hearing loss but it is preventable!

    1. I can’t hear anything else except the music
    2. I can hear someone if they yell in my ear
    3. I can hear someone talking to me arm’s distance away
