Noise control.Noise control. To help customers understand the noise control principles underlying its proprietary elastomers, the company has published an eight-page booklet called "The four-fold method of norse and vibration control." The brochure discusses the basics of acoustical a·cous·tic adj. also a·cous·ti·cal 1. Of or relating to sound, the sense of hearing, or the science of sound. 2. a. Designed to carry sound or to aid in hearing. b. absorption, acoustical barriers, vibration isolation Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations. Despite construction distinctions the essence of all vibration isolation systems are similar. and structural damping damping In physics, the restraint of vibratory motion, such as mechanical oscillations, noise, and alternating electric currents, by dissipating energy. Unless a child keeps pumping a swing, the back-and-forth motion decreases; damping by the air's friction opposes the . (E-A-R Specialty Composites) Circle 122 on card |
