Equipment for Measurement and Generation of Vibration,ed on the vibration parameter being measured, energy conversion principle, absolute or relative measurement and proximity of the transducer to the vibrating object. Then it goes on to describe many absolute measuring transducers or seismic transducers used to measure displacement, velocity, accelera

,Fundamentals of Acoustics,s associated with it. The chapter starts by describing the way humans perceive sound, followed by fundamental definitions for describing sound and aspects related to the physics of sound, as well as terminology used in acoustic measurements. It then proceeds to discuss sound wave propagation in 1-di

Equipment for Measurements in Acoustics,us parameters and technical and environmental considerations in the choice of microphones is discussed. This is followed by a description of various types of microphones available for the purpose of measurement such as carbon granule, condenser, electret capacitor, electrodynamic, piezoelectric, rib

Theory of Stress Analysis,on normal stress and strain due to axial loading of members. Different types of materials such as elastic and viscoelastic and their behaviour are described. The relationship between stress and strain for the case of axial loading, pure shear and biaxial loading are described in separate sections. T

,Basics of Experimental Modal Analysis,ucture through experiments. In any experimental modal analysis procedure, modal parameters are to be estimated from the measured frequency response functions (FRFs), i.e. from the output response and input force data and the quality of an experimental modal model is only as good as the quality of th

Vibration Experiments,n theory which has been described in Chapter 2. The presentation is such that an academician can mix and match these experiments to suit the laboratory courses being taught at undergraduate or postgraduate levels. The material will also be useful for researchers who would like to set up basic experi
