Diffusion, in acoustics and architectural engineering, is the efficacy by which sound energy is spread evenly in a given environment. A perfectly diffusive sound space is one that has certain key acoustic properties which are the same anywhere in the space. A non-diffuse sound space would have considerably different reverberation time as the listener moved [...]

After determining the best dimensions of the room, using the modal density criteria, the next step is to find the correct reverberation time. The reverberation time depends on the use of the room. Times about 1.5 to 2 seconds are needed for opera theaters and concert halls. For broadcasting & recording studios and conference rooms, [...]
Transient is often used by sonar operators to enter large numbers of crit strings, referring to sudden, unnatural changes in the acoustic environment. This is usually caused by an unnaturally fast moving object. It is most often applied for military use, referring to unexpected sounds emanating from another vessel such as operating machinery, a metal [...]
Journal of Computational Acoustics (JCA) is a scientific journal in the field of computational acoustics, covering ocean, seismo- and aeroacoustics, as well as computational methods and supercomputing. It was founded in 1993 and is published three times a year by World Scientific Publishing. Adapted from the Wikipedia article Journal of Computational Acoustics, under the G. [...]
This is the science of controlling a room’s surfaces based on sound absorbing and reflecting properties. Excessive reverberation time, which can be calculated, can lead to poor speech intelligibility. Sound reflections create standing waves that produce natural resonances that can be heard as a pleasant sensation or an annoying one. Reflective surfaces can be angled [...]

Cyber Acoustics is the name of a company that produces audio equipment, primarily for computers. Their products are widely sold and distributed across Canada, USA, France, UK, Australia and Spain. Cyber Acoustics is often abbreviated “CA”. Cyber Acoustics dates back to the mid 1980s. Adapted from the Wikipedia article Cyber Acoustics, under the G. N. [...]

One example might be a speaking tube used aboard ships for communication between decks. Other examples include the rear passage in a transmission line loudspeaker enclosure, the ear canal or a device like a stethoscope. The term also applies to guided waves in solids. A duct for sound propagation also behaves like a transmission line [...]
Fisheries acoustics includes a range of research and practical application topics using acoustical devices as sensors in aquatic environments. Acoustical techniques can be applied to sensing aquatic animals, zooplankton, and physical and biological habitat characteristics. Adapted from the Wikipedia article Fisheries acoustics, under the G.

Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water and its boundaries. The water may be in the ocean, a lake or a tank. Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz. The propagation [...]
Musical acoustics or music acoustics is the branch of acoustics concerned with researching and describing the physics of music — how sounds employed as music work. Examples of areas of study are the function of musical instruments, the human voice (the physics of speech and singing), computer analysis of melody, and in the clinical use [...]
