On Noise Reduction

It's simply what we call as unwanted sound. Your voice or somebody else's voice, your music or somebody else's music - anything that goes beyond the normal limit of sound a human eardrum can take. N-O-I-S-E. But more than that, noise is something your car produces causing a worse form of pollution in town.

Road noise is said to be a large contributor of driver fatigue. Who wouldn't get a drowsy feeling while driving your car amidst blaring horns? And what usually follows? A CRASH!

About 20 percent of road toll is caused by driver fatigue but with Cascade Audio Engineering's (CAE) floating barrier system, the statistics need not increase. CAE floating barrier system is made out of multilayered composite material that absorbs noise. It provides a physical barrier that stops sound from entering your car's cabin.

Fuel-cell vehicles like General Motors' EV1 offer the same convenience. They use electricity produced by fuel cells, a reaction of hydrogen and oxygen combined, to power motors in its wheels. Since they only emit water, they're also called zero-emission vehicles. Plus, they are smooth, quiet and pleasurable to drive like any other electric-powered vehicles. Maybe having an Acura Integra wheel cylinder is a factor to consider. Let's scrutinize the advanced technologies used by GM, as detailed in Wikipedia. These include the following:

• Aluminum frame
  
• Dent resistant side panels
  
• Anti-lock brakes
  
• Traction control
  
• Heat pump
  
• Keyless entry and keyless ignition
  
• Special one-way thermal glass to allow better heat rejection
  
• Regenerative braking
  
• Very low drag coefficient
  
• Superlight magnesium alloy wheels
  
• Self-sealing and low rolling resistance tires
  
• Automated tire pressure loss warning system
  
• Magnesium framed seats
  
• Time programmable cabin heating or cooling settings

By the way, General Motors never offered EV1 in the market. Nowadays, they're taking the lead in developing concept cars including a car that can drive by itself. Now that would surely make great noise! Sshh…
