Ever wonder why jingle bells rock? Perhaps because acoustical and audio engineers have developed technologies to help control noise and enhance the listening experience. Sound absorbers, noise barriers, and silencers for ventilation systems are just some of their ear-friendly innovations. This week's activity will ring your rock stars' chimes. Happy holidays! |
| Lesson: Sound Booth Construction
 In this activity, students in grades 7-9 explore the sound-dampening capability of materials by designing and prototyping model sound booths. They learn about how sound is reflected and absorbed, and how it travels through various materials, providing an overview of sound dampening propagation in the context of engineering.

Feature: The Real Story of Auto-Tune
 Auto-Tune is a type of sound-editing software responsible for the electronic warbling that makes many of today's popular music artists sound robotic. But it's not just a fun effect applied to vocals. The tech behind it is a powerful tool created by an engineer looking for petroleum reserves deep under our oceans. Take that, T-Pain!

| K-12 News: Nearly Half of Schools 'Failing'
 Nearly half the nation's public schools failed to meet federal benchmarks this year, up from 39 percent in 2010 and marking the largest washout rate since the No Child Left Behind Law took effect a decade ago, a new national report calculates. That's still well below the 82 percent failure rate that U.S. Education Secretary Arne Duncan predicted earlier this year, but the nonpartisan Center for Education Policy's findings still indicate an alarming trend.
