The Annals of Improbable Research (AIR) is a bimonthly magazine devoted to scientific humor, in the form of a satirical take on the standard academic journal. AIR, published six times a year since 1995, usually showcases at least one piece of scientific research being done on a strange or unexpected topic, but most of their articles concern real or fictional absurd experiments, such as a ...
Early auditory research included the early 19th century work of Georg Ohm and August Seebeck and their experiments and arguments about Fourier analysis of sounds. Later in the 19th century, German physicist Hermann von Helmholtz wrote Sensations of Tone describing the founding concepts of psychoacoustics, i.e. the relationship between the physical parameters of a sound and the percept that it ...
Acoustics is defined by ANSI/ASA S1.1-2013 as "(a) Science of sound, including its production, transmission, and effects, including biological and psychological effects. (b) Those qualities of a room that, together, determine its character with respect to auditory effects."
Tullio phenomenon, sound-induced vertigo, dizziness, nausea or eye movement was first described in 1929 by the Italian biologist Prof. Pietro Tullio.(1881–1941) [1] [2] During his experiments on pigeons, Tullio discovered that by drilling tiny holes in the semicircular canals of his subjects, he could subsequently cause them balance problems when exposed to sound.
Besides noise control, acoustical engineering also covers positive uses of sound, such as the use of ultrasound in medicine, programming digital synthesizers, designing concert halls to enhance the sound of orchestras [2] and specifying railway station sound systems so that announcements are intelligible.

Awarded Padma Shri in 1969. [13]
The field first emerged in venues like the journal Social Studies of Science by scholars working in science and technology studies and communication studies; it has however greatly expanded and now includes a broad array of scholars working in music, anthropology, sound art, deaf studies, architecture, and many other fields besides.
When the frequency of the sound field approaches the natural frequency of the bubble, it will result in large amplitude oscillations. The Keller–Miksis equation takes into account the viscosity, surface tension, incident sound wave, and acoustic radiation coming from the bubble, which was previously unaccounted for in Lauterborn's calculations.
