Crank It Down Program

Crank It Down Colorado Kids

Crank It Down is an outreach effort by NHCA to encourage local communities and schools to educate children and adolescents regarding the risk of noise induced hearing loss from hazardous noise exposures. Many of our members have conducted small local projects and/or direct and promote national campaigns for children and hearing conservation.

We hope this webpage will grow as a central resource linking curricula and promotions for different age groups. Please submit additional links and promotional items to share to the NHCA Task Force on Hearing Conservation Education for Children and Adolescents (
