Vibration refers to the oscillatory motion of particles or objects around an equilibrium point. It occurs in various forms, including mechanical vibrations in machines and structures, acoustic vibrations in air or other media, and seismic vibrations in the ground. In engineering, the study of vibration focuses on understanding the causes, effects, and control mechanisms of these oscillations.
Sound is the propagation of mechanical waves through a medium, typically air, caused by vibrating objects. In engineering, the study of sound focuses on understanding its generation, transmission, and effects on human health and the environment.
How are sound and vibration measured? Sound and vibration data acquisition devices are utilized for capturing, analyzing, and understanding the acoustic and mechanical behavior of various systems and environments. Vibration measurement instruments serve a wide range of purposes across multiple industries and applications, from automotive, manufacturing, environmental monitoring, and research and development. Vibration measurements and trends can be used as an indication of machine health, and accurately measuring vibration using an accelerometer or other vibration sensor can help predict machine failure and schedule maintenance.
When selecting a DAQ device for sound and vibration measurement, factors such as the number of input channels, sampling rate, resolution, compatibility with sensors, software support, and budget constraints are crucial. Digilent and Measurement Computing offers solutions to directly measure IEPE-type vibration sensors, accelerometers or voltage inputs with no added signal conditioning using USB data acquisition (DAQ) devices.
