We have many years of combined experience in Acoustics, and Shock Consulting. Technology development is something that we are specialists at. We specialize in solving problems, or any issues relating to Noise, Shock, and Acoustical Consulting Services. QRDC, Inc. patented technology using our professional engineers improves noise and vibration characteristics of products or components, helping manufacturers solve noise and vibration problems and reduce production costs, while saving end users maintenance and energy costs.
some fixed time (see harmonic motion). Sound is produced by the vibrations of a body and is transmitted through material media in pressure waves made up of alternate condensations (forcing of the molecules of the medium together) and rarefactions (pulling of the molecules of the medium away from one another). In sound the vibration is longitudinal, for the movement is to and fro along the direction in which the sound is traveling. When a sound wave of one frequency strikes a body that will vibrate naturally at the same frequency, the vibration of the body is called sympathetic vibration. A reinforcement of sound resulting from sympathetic vibration is called resonance. When the vibrations of a sound-producing body cause another body to vibrate in the same frequency, not normally its own, the vibration is known as forced vibration. Heat is commonly defined as the energy of molecules, part of which consists of the energy of their vibrational motion.
Vibration isolation technology is our specialty implemented with our expertise in mechanical engineering. We have ground breaking techniques for Vibration and noise control. All of our employees have educations from top universities. Mechanical engineering is our core compentency Structural Analysis, and Structural noise. Industrial problems can result in an Acoustics problem at your facility. We are your premier service provider. Industrial noise can be solved by actively utilizing Vibration monitoring techniques.
