Government intervention is not always openly welcomed and can meet with very vocal opposition, especially in California. But after Southern California was recently shaken, rattled, and rolled by a 5.4 magnitude earthquake, building inspectors found very little evidence of any significant structural damage. Why is that? Because state government enforced building codes developed after the near catastrophic 6.7 magnitude Northridge quake over a decade ago vastly improved structural integrity, adding safety and security for the people living in this quake prone area and making the area a great example for potential quake epicenters worldwide.

Residents who live near wind turbines say to believe the annoying noise you have to hear it for yourself. Quick thinking German Engineers are coming to the rescue by combining passive noise reduction with active noise cancellation technology to make this energy source a welcome addition to our global energy needs.

Feeling the bumps and ruts in the road more and more these days? Maybe your shock absorbers need service or replacement. You can head to your local service shop and have them professionally inspected and possibly replaced, or perhaps you'd like to tackle the service yourself, this article shows what needs to be done.

Those who live near power transmission equipment and substations know all about the noisy buzz of power transformers and the effects of its drone on daily life. But alas, every noise problem has a solution. Read how one substation underwent noise reduction modifications and discover which approach worked, which didn't, and why.

Noise is all around and our governments set benchmarks for noise control levels and provide legislation to limit noise pollution. This informative Web page can lead you to many of the best sources on noise pollution including U.S. Congressional documents, Federal regulation codes, and noise related reports and articles.

Active and passive vibration control are traditional means to reduce noise and vibration in systems. Now a patented approach of Vibration Control by Confinement (VCC) promises a range of applications from micro motor spindles to military transport aircraft. The approach diverts regions of energy to reduce the flow of noise and vibration.

Today it's best to think about what could happen and implement security measures to stop even the unthinkable. The first line of defense for critical facilities, including embassies, nuclear plants, military bases, and corporate building, is barricade systems. See how one company is thriving in this new security marketplace.

Moving massive machinery along assembly lines with overhead cranes or conveyor and rail systems can be awkward and dangerous. Obstacles include motion limiting supports and rails. A better alternative might be air casters and bearings that float heavy equipment down the line on a cushion of air with just the nudge of a hand.

Summer is great for night-time viewing of the heavens. But when both amateur and professional astronomers try catching a glimpse of their favorite planet or galaxy from a deck, dock, or pier, they might experience unwanted vibrations. The solution is to add a helical isolator system to cushion fragile optics and to help them focus.

Acoustax, from Diamond Manufacturing, is a stackable, lightweight noise barrier designed to remedy a broad range of community and industrial noise problems. Certified tests prove Acoustax absorbs a broad frequency spectrum and prevents noise transmission through the barrier, making it ideal for use as noise walls, absorbing twice as much noise as painted concrete block.
