Mechanical vibrations caused by charged cell membranes and walls is a leading hypothesis for acoustic emission generation. Myosins and other mechanochemical enzymes which use chemical energy in the form of ATP to produce mechanical vibrations in cells may also contribute to sound wave generation in plant cells. These mechanisms may lead to ...
The musical leaf is one of any leaves used to play music on. It goes by many names, including leaflute , leaf flute , leaf whistle , gum leaf , and leafophone . In Cambodia, it is called a slek ( Khmer : ស្លឹក ) and is played by country people in Cambodia , made from the leaves of broad-leaf trees , including the sakrom and khnoung trees.
Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans). [1] This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they ...
The AP results in the accumulation of Ca2+ ions. If the hairs are then left alone, the Ca2+ will dissipate. If another hair is stimulated within 30 seconds of the first hair, however, another AP will fire and the [Ca+] will reach a threshold triggering changes in cell turgor in the petiole. This will cause the trap to swiftly snap shut ...
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [1] [2] [3] psychophysics, [4] organology [5] (classification of the instruments), physiology, [6] music theory, [7] ethnomusicology, [8] signal processing and instrument building, [9] among other disciplines.
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
The incorporation of bird song in music is one of the most widely studied forms of biomusic. Notable in this regard is the French composer Olivier Messiaen who began incorporating accurately transcribed bird songs into his music in 1952. One obstacle facing the use of bird songs in music is their complexity and usually very high register.
