Abstract

What are the best materials to use for blocking out unwanted noise from the environment? You can build a test box (or test frame) around an audio speaker. Use a sound level meter to measure the speaker output. Use different materials to cover the walls of your test box (or frame), and see which materials do the best job at blocking the sound. For a more advanced project, perform your tests using different sound frequencies. Are some materials better at blocking certain frequencies than others? Which sound frequencies are most difficult to block? Why? (Boyd, 2004; Wandro, 2004)

Career Profile
Any time you hear music at a concert, a live speech, the police sirens in a TV show, or the six o'clock news you're hearing the work of a sound engineering technician. Sound engineering technicians operate machines and equipment to record, synchronize, mix, or reproduce music, voices, or sound effects in recording studios, sporting arenas, theater productions, or movie and video productions.

Career Profile
What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically… Read more
Career Profile
If you turned on a faucet, used a bathroom, or visited a public space (like a road, a building, or a bridge) today, then you've used or visited a project that civil engineers helped to design and build. Civil engineers work to improve travel and commerce, provide people with safe drinking water and sanitation, and protect communities from earthquakes and floods. This important and ancient work is combined with a desire to make structures that are as beautiful and environmentally sound, as they… Read more
Career Profile
Do you dream of building big? Civil engineering technicians help build some of the largest structures in the world—from buildings, bridges, and dams to highways, airfields, and wastewater treatment facilities. Many of these construction projects are "public works," meaning they strengthen and benefit a community, state, or the nation. Read more
