Acoustics is the science concerned with the production, control, transmission, reception, and effects of sound. Wolf Research continues to look into the many aspects of the fundamental physical processes involved in waves and sound and into possible applications of these processes in modern life in such areas as:
Aeroacoustics: study of aerodynamic sound, generated when a fluid flow interacts with a solid surface or with another flow.
Architectural acoustics: study of sound waves distribution in variously shaped enclosed or partly enclosed spaces with effects of sound waves on objects of different shapes which are in their way. Mostly concentrated on how sound and buildings interact, including the behavior of sound office buildings, factories and homes.
Biomedical acoustics: study of the use of sound in medicine, for example the use of ultrasound for diagnostic and therapeutic purposes.
Physical acoustics: study of the detailed interaction of sound with materials and fluids and includes, for example, sonoluminescence (the emission of light by bubbles in a liquid excited by sound) and thermoacoustics (the interaction of sound and heat).
Structural acoustics and vibration: study of how sound and mechanical structures interact; for example, the transmission of sound through walls and the radiation of sound from vehicle panels.
Ultrasonics: study of high frequency sound, beyond the range of human hearing.
Nonlinear Acoustics: study of large amplitude sound waves that propagate according to the Westervelt-Lighthill equation (in fluids) and analogous theories in other types of media.
