Applying Health Skills Advocacy. Work with classmates to create a campaign that raises awareness about hearing loss. Brainstorm ways teens can reduce exposure to damaging noise levels and protect their hearing. Use effective strategies to promote hearing protection. Reviewing Facts and Vocabulary 1. Identify the three main parts of the ear and the structures that can be found in each part. 2. Define the term tinnitus. 3. Examine the effects of health behaviors on hearing: What effect can loud noises have on hearing? Thinking Critically 4. Analyzing.

Under what circumstances might you need to protect yourself from sensorineural hearing loss? How might you do so? W O R D P R O C E S S I N G Use a word- processing program to record ideas and plan your campaign. See health.glencoe.com for tips on how to get the most out of your word-processing program. Lesson 4 Ears and Hearing Protection 379 Problems of the Ear earing loss can be divided into two categories: conductive H and sensorineural. Conductive Hearing Loss In conductive hearing loss, sound waves are not passed from the outer to the inner ear, usually because of a blockage or injury to the inner ear. For example, middle-ear infections may lead to rupture of the eardrum. Persistent buildup of fluid within the middle ear, often caused by infection, is most common in children. Sensorineural Hearing Loss Sensorineural hearing loss results from damage to the cochlea, the auditory nerve, or the brain. is a condition in which a ringing, buzzing, whistling, roaring, hissing, or other sound is heard in the ear in the absence of external sound. Tinnitus can occur as a result of natural aging, health conditions such as high blood pressure, or overexposure to loud noise. To protect your ears from this condi- tion, lower the volume of the source of noise. Wear earplugs in noisy environments, when operating machinery, and at loud con- certs or sporting events. Limit the length of time you are exposed to loud noise to reduce the chance of permanent damage. Tinnitus Consideration. Treating all people with consideration and respect is the first step toward forming a friendship with someone you have just met. These qualities are just as important when meeting and communicating with a person with a disability, such as a hearing impairment. Consider the difficul- ties a hearing impairment would cause. List suggestions for communicating with a hearing- impaired person in ways that would show consideration and respect.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
