At Glacier Bay, our innovative energy management technologies include the control of sound. Everyone loves quiet. Unless you are in the speaker business, chances are pretty good that your customers draw a direct line between low noise and high quality. Of course, getting noise levels down to where you'd like them to be can be a real challenge. Conventional sound damping materials rely on mass and volume to do their job. While we all want to stamp out noise, many situations cannot tolerate the added weight and space it takes to do the job right.

That is exactly the situation we found ourselves in when we began designing our diesel generators. We wanted small size, light weight and quiet operation. Getting all three was going to be a challenge using conventional materials. What was needed was a completely new approach to sound attenuation. A material that effectively dispersed the energy contained in sound waves without relying on lead sheets, filled vinyl, coated metals, concrete, sheet rock or other mass-dependent products. When we couldn't find what we needed, we decided to invent our own.

"Ultra-dB" is our trade name for a completely unique (patent-pending) way to kill noise. Rather than relying on mass to block the sound waves, Ultra-dB uses sheets of loosely connected particles to harness and disperse the energy. Upon being struck by a sound wave, these particles begin to vibrate, effectively transforming the energy in the wave into mechanical motion.  The structure of the particles ensures that each will vibrate at a slightly different resonate frequency allowing each one to dampen the motion of the particle next to it.  The end result is an acoustic insulation that is only about 50% the weight and thickness of conventional materials. Ultra-dB products can be tuned to specific frequencies and constructed from various materials to match the environmental requirements of the application. They are particularly well suited for transportation, industrial equipment, power generation or any application where high quality sound attenuation is required without excessive weight and space.
