The Scream Response
Screaming is a universal sound that is designed to evoke a response. New research not only identifies what kind of sound can be defined as a “scream,” but it also pinpoints how the brain responds to it. While most people would characterize a scream as being loud and high-pitched, it is the “roughness” of the sound (how fast the sound changes in loudness) that is its defining characteristic. While speech patterns only have slight differences in loudness, screams can modulate very quickly. Researchers found that it is this “acoustic roughness” that activates the region of the brain (amygdala) that processes the fear response. The rougher the sound is, the more terrifying the brain interprets it as being.

Secondhand Smoke Threatens Teens Hearing
Many teens are already at high risk for permanent hearing loss due to exposure to high-volume music coming from their mp3 players and concert venues. Now, there is also research suggesting that those exposed to secondhand smoke as children have a higher risk of suffering from low- and high-frequency hearing loss during their teens. This finding comes as troubling news to the estimated 60 percent of children in this country who are exposed to some kind of secondhand smoke. It may be even more concerning that, when researchers studied the health data of 1,533 children between the ages of 12 and 19, 80 percent of the adolescents with hearing loss were unaware that their hearing was comprised. Testing is recommended.
Teen that are exposed to passive smoke should be more closely monitored for hearing impairment. They also should be educated about risk factors of hearing loss, such as noise pollution and second-hand smoke.
