How Hearing Loss Occurs

Hearing loss can result from damage to structures or nerve fibers in the inner ear that respond to sound. This type of hearing loss, termed “noise-induced hearing loss,” is usually caused by exposure to excessively loud sounds and cannot be medically or surgically corrected.

Sound intensity is measured in decibels with a sound level meter. Noise-induced hearing loss can result from a one-time exposure to a very loud sound (at or above 120 decibels), blast, impulse, or by listening to loud sounds (at or above 85 decibels) over an extended period. The louder the sound, the shorter the time period before hearing damage occurs.

Signs and Symptoms of Hearing Loss

Because the damage from noise exposure is usually gradual, a person might not notice or might ignore signs of hearing loss until more pronounced symptoms of permanent hearing loss become evident.3 Noticeable signs of hearing loss can include the following:

  • Muffled or distorted hearing
  • Difficulty hearing sounds such as birds singing, crickets chirping, alarm clocks, watch alarms, telephones, or doorbells
  • Difficulty understanding speech during telephone conversations or while participating in group conversations
  • Pain or ringing in the ears (tinnitus) after exposure to excessively loud sounds

If a child or adolescent experiences any of these signs, he or she should tell a parent, teacher, or other trusted adult. Often, family members, coworkers, or friends are the first to notice hearing problems in others. The only accurate way to determine the extent and degree of hearing loss is through evaluation by an expert trained to test hearing (audiologist) or other qualified professional.

How Much Noise Is Too Much?

Noise exposures add up throughout daily activities. However, certain events, behaviors, and environmental factors in and out of the school setting can expose young people to unsafe sound levels:

  • Exposure to sound levels that exceed safe listening levels, such as at rock concerts or band practice, can cause hearing damage if it occurs frequently or for long periods of time.
  • Listening to portable media devices such as compact disc and MP3 players at high volume levels (above 85 decibels) for long periods of time can cause similar damage.
  • In the school setting, children and adolescents can be exposed to sounds that can damage their hearing, such as in band or shop class or attending school events (dances, athletic events) with excessive sound levels.
  • Construction and maintenance activities in or around the school can also expose students to harmful sound levels.

Communicating with People with Hearing Loss

Successful communication requires the efforts of all people involved in a conversation. Even when the person with hearing loss utilizes hearing aids and active listening strategies, it is crucial that others involved in the communication process consistently use good communication strategies, including the following:
  • Face the hearing impaired person directly, on the same level and in good light whenever possible. Position yourself so that the light is shining on the speaker’s face, not in the eyes of the listener.
  • Do not talk from another room. Not being able to see each other when talking is a common reason people have difficulty understanding what is said.
  • Speak clearly, slowly, distinctly, but naturally, without shouting or exaggerating mouth movements. Shouting distorts the sound of speech and may make speech reading more difficult.
  • Say the person’s name before beginning a conversation. This gives the listener a chance to focus attention and reduces the chance of missing words at the beginning of the conversation.
  • Avoid talking too rapidly or using sentences that are too complex. Slow down a little, pause between sentences or phrases, and wait to make sure you have been understood before going on.
  • Keep your hands away from your face while talking. If you are eating, chewing, smoking, etc. while talking, your speech will be more difficult to understand. Beards and moustaches can also interfere with the ability of the hearing impaired to speech read.
  • If the hearing impaired listener hears better in one ear than the other, try to make a point of remembering which ear is better so that you will know where to position yourself.
  • Be aware of possible distortion of sounds for the hearing impaired person.They may hear your voice, but still may have difficulty understanding some words.
  • Most hearing impaired people have greater difficulty understanding speech when there is background noise. Try to minimize extraneous noise when talking.
  • Some people with hearing loss are very sensitive to loud sounds. This reduced tolerance for loud sounds is not uncommon. Avoid situations where there will be loud sounds when possible.
  • If the hearing impaired person has difficulty understanding a particular phrase or word, try to find a different way of saying the same thing, rather than repeating the original words over and over.
  • Acquaint the listener with the general topic of the conversation. Avoid sudden changes of topic. If the subject is changed, tell the hearing impaired person what you are talking about now. In a group setting, repeat questions or key facts before continuing with the discussion.
  • If you are giving specific information — such as time, place or phone numbers — to someone who is hearing impaired, have them repeat the specifics back to you. Many numbers and words sound alike.
  • Whenever possible, provide pertinent information in writing, such as directions, schedules, work assignments, etc.
  • Recognize that everyone, especially the hard-of-hearing, has a harder time hearing and understanding when ill or tired.
  • Pay attention to the listener. A puzzled look may indicate misunderstanding. Tactfully ask the hearing impaired person if they understood you, or ask leading questions so you know your message got across.
  • Take turns speaking and avoid interrupting other speakers.
  • Enroll in aural rehabilitation classes with your hearing impaired spouse or friend.
