Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians.The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan …

It is one of the oldest Chinese instruments, with images depicting its kind dating back to 1100 BCE, and there are original instruments from the Han dynasty that are preserved in museums today. Traditionally, the sheng has been used as an accompaniment instrument for …

Audio engineers working in research and development may come from backgrounds such as acoustics, computer science, broadcast engineering, physics, acoustical engineering, electrical engineering and electronics.Audio engineering courses at university or college fall into two rough categories: (i) training in the creative use of audio as a sound engineer, and (ii) training in …

Anisotropy (/ ˌ æ n aɪ ˈ s ɒ t r ə p i, ˌ æ n ɪ-/) is the property of a material which allows it to change or assume different properties in different directions, as opposed to isotropy.It can be defined as a difference, when measured along different axes, in a material's physical or mechanical properties (absorbance, refractive index, conductivity, tensile strength, etc.).

Field theory interpretation. For an irrotational vector field in three-dimensional space, the inverse-square law corresponds to the property that the divergence is zero outside the source. This can be generalized to higher dimensions. Generally, for an irrotational vector field in n-dimensional Euclidean space, the intensity "I" of the vector field falls off with the distance "r" following the ...

Theory. A whispering gallery is most simply constructed in the form of a circular wall, and allows whispered communication from any part of the internal side of the circumference to any other part. The sound is carried by waves, known as whispering-gallery waves, that travel around the circumference clinging to the walls, an effect that was discovered in the whispering gallery of …

Architectural acoustics (also known as building acoustics) is the science and engineering of achieving a good sound within a building. Architectural acoustics can be about achieving good speech intelligibility in a theatre, restaurant or railway station, enhancing the quality of music in a concert hall or recording studio, or suppressing noise to make offices and homes more …

Stanford University has many centers and institutes dedicated to the study of various specific topics. These centers and institutes may be within a department, within a school but across departments, an independent laboratory, institute or center reporting directly to the dean of research and outside any school, or semi-independent of the university itself.
