How Your Brain Understands What Your Ear Hears

helps students learn how audio and visual cues can help communication, how loudness is measured, how changes in the "hearing pathway" may affect hearing, and how to prevent hearing loss. Animations (under "student activities") show an ear hearing the Gettysburg Address in 5 languages, a graphic display of pitch and volume, and how sounds are converted into electrical impulses and sent to the brain.

Interesting Fact:

Scientific research has shown that the brain never stops changing and adjusting to its environment.1 This ability is important for acquiring new knowledge and for compensating for deficiencies that result from age or injury. The ability of the brain to “reprogram” itself is called plasticity. Special brain exercises, or training techniques, exploit brain plasticity to help people cope with specific language and reading problems.
