Read full description of the books Theory and Applications of Instantaneous Intensity Analysis: Advanced Analysis Method for Engineering Acoustics:
The Fourier transform has become one of the most analytical tools, which is used for the sound intensity analysis and acoustic measurement in many industrial areas. But this method has the limitation that sound sources to measure need to be stationary and it does not provide true characteristics of time varying signals. Instead of the Fourier transform, advanced analysis methods such as the short-time Fourier transform, the Wigner-Ville distribution and the wavelet transform were proposed. These instantaneous spectrum analysis methods can be applied for obtaining the instantaneous intensity of non-stationary signals. This book shows the basic concepts of the Fourier transform and other instantaneous spectrum analysis, and also gives the theory and applications of instantaneous intensity analysis methods including their advantages and disadvantages. The instantaneous structural intensity analysis and other acoustical analysis methods, which provide readers useful techniques for engineering acoustics, are also presented.
Read information about the authorTakaaki Musha (born September 17, 1951) is a Japanese research engineer. He received M.E. and Ph.D. degrees from Shinshu University, Nagano, Japan, in 1977 and 1994, respectively, both in material science and mechanical engineering. He joined the Advanced Space Propulsion Investigation Committee (ASPIC) in 1994, which was organized under the Japan Society for Aeronautical and Space Sciences, the purpose of which was to study non-chemical space propulsion systems.
He has been working for the Technical Research & Development Institute of the as a research engineer on naval systems. He is a member of the Institute of Electrical and Electronics Engineers (IEEE) , the Japan Society of Mechanical Engineers and the Marine Acoustics Society of Japan. He has published numerous articles in scientific and engineering journals. In addition to acoustics, his research interests include physics of faster-than-light (also known as superluminal) phenomena, anti-gravitational propulsion, and non-conventional energy sources. From 1992 to 1996, he conducted experiments to confirm the Biefeld-Brown effect solely and later cooperated with the research group of the Honda R&D institute, and obtained positive results. He also derived the formula to explain the electrogravitic effect from the weak-field approximation of Einstein's General Relativity Theory; a formula that was similar to the formula obtained by Boyko V.Ivanov, which was derived from the Weyl-Majumdar-Papapetrou solutions of the General Relativity Theory.
Former senior research scientist at the Technical Research and Development Institute of the Ministry of Defense, Japan.
Director of the Advanced-Science Technology Research Organization (Japan)
Editor-in-Chief, Journal of Space Exploration (Mehta Press)
