Dangerous Decibels Educator Resource Guide and DVD


OHSU # 0532-C

Noise-induced hearing loss can be prevented!! The OHSU Dangerous Decibels® project mission is to significantly reduce the prevalence of noise-induced hearing loss and tinnitus (ringing in the ear) through exhibits, educational outreach, research and a variety of classroom materials and resources for educators.


The Educator Resource Guide is an illustrated, spiral paperback (8.5 x 11 and 105 pages) K-8 classroom supplement with hands-on activities, background information, and experiments. Activities cover the anatomy and physiology of hearing, how to prevent noise-induced hearing loss, and the physics of sound.
