The handbook covers the topics of vibro-acoustics, noise, harshness and their related applications in detail. Various topics covered in this handbook are acoustics and vibration metrology, environmental noise measurements, building acoustics, acoustical meta-materials, underwater acoustics, soundscape approach, beam forming approach, 3D noise mapping, in-situ acoustical testing, etc. The handbook would provide a single window source of up-to-date information to the researchers, acousticians, noise and vibration control engineers, metrologists, industry, university graduates, masters, academicians, administrators, policymakers, regulators, and other stakeholders for a better understanding of vibro-acoustics, noise, harshness and related applications.
