You had an initial audiogram, which determined for each ear, your degree of hearing loss. The audiogram measured the lowest volume or decibel that you could hear pure tone signals at different frequencies. The softest sounds you heard at each pitch at least 50 percent of the time (your hearing threshold) was considered your hearing level. The results of an audiogram can be clarified when combined with other tests, such as the ability to recognize or understand words, as well as hearing capability in noisy environments. Keeping a Journal One of the better tools that can help you and your audiologist ensure you reach your hearing goal is a Sound Experience Journal, as provided by your AudigyCertified™ expert. When creating your journal, you first defined what three hearing situations you wanted to track and the expected sound environment for each situation (loud, moderate, or quiet). We recommend you keep up on your journal, so you’ll maximize your hearing experiences within your selected lifestyle. You can do this by following through the journal and listing the specific activity performed (e.g., dining in a restaurant) and describing the experience. We encourage you to list any new sounds heard and the quality of those sounds. “Noon, Room, Pool” In addition to keeping a journal, you’ll be asked to perform sound comprehension tests with a companion at home.

Please send your information to [email protected]. It’s Too Loud. You’re Not Too Old. It’s a Noisy, Noisy, Noisy, Noisy World There’s really no avoiding it—we live in a world full of all sorts of noise and distraction. Since the onset of the Industrial Revolution, our world—once a tonal palette of songbirds, rolling waves and blustery breezes—has become an unrelenting (not to mention unnatural) environment of electric hums, screeching semis and factory clang. Of course, this barrage of noise is one we’ve grown accustomed to. More appropriately, we have become desensitized by the racket that surrounds us, both mentally and physically. Ironically, we often use a product, like an MP3 player, Walkman or Discman, to 1 in 5 U.S. adolescents now suffer from hearing loss. 1988 and 1994, compared with their reported hearing loss between 2005 and 2006, uncovered a 31 percent increase in hearing loss among those between 12 and 19 years old.” Hearing Loss Can Affect Development Researchers say this means one in five adolescents now suffer some sort of hearing impairment. The reported hearing loss in the study is classified as slight to mild, but can nonetheless negatively affect a child’s socialemotional development, impair their speech and language development, as well as impede their academic performance. Tip for Parents: Apple has created a function that limits the volume on your child’s iPod or iPod Shuffle. Once the volume is locked, a combination is required to change the setting. Go to http://support.apple.com for details. insulate us from the external noises of the world, by drowning them out with even louder sounds channeled directly into our ears. It’s really no wonder that hearing loss is so widespread—it affects tens of millions of people in the U.S. alone. And though hearing loss is largely considered an affliction that exclusively affects older generations, hearing loss among U.S. adolescents is sharply on the rise. Though many would be quick to cite the earbuds themselves as the primary offender in causing hearing loss among adolescents, it is more likely prolonged exposure to high levels of noise in addition to the earbuds that causes the damage. This extended exposure to loud noise causes hearing loss by destroying the cilia (small hairs) in the inner ear. Cilia respond to different frequencies, sending different sounds to the brain for interpretation. According to the latest research published When the cilia are destroyed, the brain in The Journal of the American Medical is unable to interpret the information it Association, “the prevalence of hearing has received, resulting in an individual’s loss among U.S. adolescents between inability to understand speech.

Additionally, the study found that “adolescents and young adults typically underestimate symptoms of loud sound, tinnitus and temporary hearing impairment during music exposure and underreport concern for these conditions.” Prevent Hearing Loss Now So, what’s the solution? Many Audiologists would recommend a worthwhile investment in your child’s or grandchild’s hearing—and ultimately their social and academic future—by swapping out their MP3 player’s stock earbuds for a set of custom-molded earbuds, specially designed by a hearing care professional whose goal is to provide the listener with optimum sound in the safest way possible. Custom earmolds’ individually-created tips are made specifically for the wearer by lab experts, while the acoustic design of custom MP3 earmolds optimize the sound quality of standard in-ear headphones that come with MP3 players (and other similar audio equipment). Custom earmolds allow a perfect fit—even for exercise—guaranteeing an excellent acoustic seal, while, more importantly, “Adolescents and young adults typically underestimate symptoms of loud sounds, tinnitus and temporary hearing impairment during music exposure and underreport concern for these conditions.” making lower volumes more satisfying to the listener to protect their hearing. Though the nature of popular music will always change as time goes on, an adolescent’s relationship with it most certainly will not. Why not give them the opportunity to enjoy it for a lifetime, by giving them the education and tools they deserve to maintain their optimum hearing health? After all, music— much like our hearing and communication— is a gift that we can share across generations. Your AudigyCertified™ professionals would love to ensure that your family’s enjoyment of these gifts is anything but lacking. Source: JAMA, August 18, 2010— Vol. 304, No. 7 “Change of Prevalence in Hearing Loss in US Adolescents” The Speed of Sound Have you ever thought about why inhaling from a helium balloon gives your voice that temporarily goofy Donald Duck voice? It can be explained by understanding how fast sound moves through different objects. The speed of sound is measured by the velocity of a sound through a medium, such as a gas or solid. For example, the speed of sound in air is 768.095 mph at a temperature of 68°F. At sea level, this means sound moves faster than 750 miles per hour. In general, the denser the medium, the faster sound travels. Sound travels faster through steel than through wood, and it travels four times faster through water than through air. That’s why your voice sounds so much higher when you inhale helium. Since helium is much denser than air, it travels at a much higher rate causing it to sound high-pitched. The Big Boom Theory A sonic boom is the sound of an object moving faster than the speed of sound. This means the sound is moving faster than 750 mph (at sea level). As a jet flies through the air, it creates a wave of pressure in front. If the jet travels less than the speed of sound, air particles have enough time to part in front of it, much like waves part in front of a ship. However, when the jet flies faster than the speed of sound, also referred to as Mach 1, the pressure waves are compressed and overlap, resulting in what’s known as a sonic boom. The loudest sonic boom every recorded was 144 pounds of overpressure– created by an F-4 fighter jet flying just over Mach 1 at an altitude of 100 feet. There were no injuries, which is amazing, since just five pounds of overpressure can cause minor damage to buildings. Recently, an experimental jet set a record for hypersonic flight, traveling at Mach 6—six times the speed of sound! It’s Too Loud. You’re Not Too Old.
