Such a definition, it would be fair to say, matches the popular and standard definition of sound in the West; the primary definition of sound in the 10th edition of the Concise Oxford English Dictionary is “vibrations which travel through the air or another medium and are sensed by the ear” (sound waves are those traveling vibrations). More fully stated, sound may be defined as a pressure ...
Feb 9, 2024 · Rhythm: Where Synchronicity Meets Sonics and Science. Rhythm is the symphonic pattern of all life and the basis of biological evolution. Frequencies, timbres, and the passage of beats through time ...
Aug 23, 2021 · Andrea investigates the evolutionary and biological bases of rhythm cognition and flexible sound production, and the role they played in the origins of music and speech in our species. He performs sound recordings and behavioural non-invasive experiments in several animal species (mostly seals) as a comparative effort to understand the evolutionary history of human capacities.

It discusses the different types of brain waves, first discovered in the 1920s by Hans Berger, including alpha, beta, delta, theta, and gamma waves; the rhythm of heart beats; the wave motion of peristalsis that travels all the way down the alimentary tract from throat to rectum; the different wave motion in the locomotion of animals such as worms, snakes, centipedes, and millipedes; and the ...
It permeates the entire being, and according to its particular influence either slows or quickens the rhythm of the blood circulation; it either wakens or soothes the nervous system. It arouses a person to greater passions or it calms him by bringing him peace. According to the sound and its influence a certain effect is produced.
Oct 31, 2023 · The speed of sound waves differs based on altitude, temperature, and medium. At sea level and a temperature of 20º C (68º F), sound waves travel in the air at about 343 meters per second. As is true for all waves, there are four main characteristics of a sound wave: frequency, wavelength, period, and amplitude. Frequency is the number of ...

The sound wave may also be reflected from the object or it may diffract around the object. Thus, a sound wave propagating outward from a vibrating object can reach the eardrum of a listener causing the eardrum to vibrate and initiate the process of hearing. Sound waves can be mathematically described in two ways, that is, in two domains.
