Wave - Wikipedia

The amplitude of a wave may be constant (in which case the wave is a c.w. or continuous wave), or may be modulated so as to vary with time and/or position. The outline of the variation in amplitude is called the envelope of the wave. Mathematically, the modulated wave can be written in the form: (,) = (,) ⁡ (− +) ,where (, ) is the amplitude envelope of the wave, is the wavenumber and is ...

A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases. Loudness is measured in units called decibels decibel, abbr. dB, unit used to measure the loudness of sound. It is one tenth of a bel (named …

Laser Doppler vibrometer - Wikipedia

A laser Doppler vibrometer (LDV) is a scientific instrument that is used to make non-contact vibration measurements of a surface. The laser beam from the LDV is directed at the surface of interest, and the vibration amplitude and frequency are extracted from the Doppler shift of the reflected laser beam frequency due to the motion of the surface. The output of an LDV is generally a continuous ...

Whole body vibration - Wikipedia

Whole body vibration (WBV) is a generic term used when vibrations (mechanical oscillations) of any frequency are transferred to the human body.Humans are exposed to vibration through a contact surface that is in a mechanical vibrating state. Humans are generally exposed to many different forms of vibration in their daily lives.

Amplitude of vibration of WBV machines. Vibration machines are meant to vibrate. And any vibration, be it for these machines or for anywhere else on earth, is measured by two key parameters - vibration amplitude and vibration frequency.The amplitude of vibration of your machine will play a critical role in determining the goodness of vibration quality that your body gets exposed to.

What’s the Amplitude of that Vibrator? | Solutions In Motion

That said, when asked “hey what’s the amplitude of the 1200 VMSAC pneumatic vibrator?” you can’t fire back, ”Oh it’s 0.157 of an inch” sorry, it just doesn’t work that way. Amplitude is not an independent parameter of the vibrator, it very much depends on the structure to which it’s mounted and the freedom of movement of that ...

The benefits of vibration - Vibration Trainers from ...

The amplitude of a vibration exercise machine is simply a measurement of how far the platform which the user stands, on actually moves. This is the physical distance of travel of the platform, typically measured in millimetres (mm). This measurement is vertical for oscillating machines and sideways for triplanar or spiral rotational machines.

Forced Vibrations & Resonance – free vibrations, damping ...

Free vibrations are oscillations where the total energy stays the same over time.This means that the amplitude of the vibration stays the same. This is a theoretical idea because in real systems the energy is dissipated to the surroundings over time and the amplitude decays away to zero, this dissipation of energy is called damping..
