Objective: VIPER is a European Joint Doctorate network focused on research in VIbroacoustic
of PERiodic media.
In this chapter sound therapies, vibroacoustic
therapy, and biofeedback and resonant frequencies have been introduced in a very superficial manner.
Techniques to Diagnose Power Transformer.
The analysis inspects the vibroacoustic
performance (that is, frequency response) of a vehicle by simulating the fluid-solid interaction (air and the trim components) within the passenger cabin (the acoustic cavity).
It is used to predict interior noise and vibration in automobiles, aircraft and construction equipment cabs, as well as the radiated noise from ships and the vibroacoustic
environments for spacecraft.
These defects generate changes in the vibroacoustic
Castelo Branco and Rodriguez first documented vibroacoustic
disease among airplane technicians, commercial and military pilots, mechanical engineers, restaurant workers, and disc jockeys for exposure to large pressure amplitude and low frequency sound ([greater than or equal to] 90 dB sound pressure level, [less than or equal to] 500 Hz) (Castelo Branco & Rodriguez, 1999; Maschke, 2004).
Wigram (1996) developed his ideas during Vibroacoustic
Therapy research, and later published them as a list of the potential elements in sedative music and a list of the potential elements in stimulating music (Wigram, Pederson & Bonde, 2002).
diagnostics of the developing defects].
There is extensive evidence that such exposures can lead to a variety of diseases, including vibroacoustic
disease is a well-documented occupational hazard caused by exposure to high levels of infrasound and low-frequency sound.
Research of lawfulness of an impulse and vibroacoustic
wave transmission and in solving diagnostic problem lead to necessity of selecting not only information positions for installation of sensors but to evaluate the character of vibration impulse under defects, to set diagnostic regime, determine frequency area of measuring and manner of processing vibroacoustic
information to obtain characteristic diagnostic facts.
