This device uses a single transducer element with a dish or conical-shaped sound reflector to focus the signals, in a similar manner to a reflecting telescope. This type of hydrophone can be produced from a low-cost omnidirectional type, but must be used while stationary, as the reflector impedes its movement through water.
The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
Ecomusicology considers aspects of environmental sustainability within music production and performance. For example, the relationship between a demand for a certain musical instrument as well as the costs and impacts of its production, has been an area of interest for Ecomusicologists investigating the sustainability of the consumption and production of music or musical instruments.

A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...
In physics, sound energy is a form of energy that can be heard by living things. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.
In music, soundscape compositions are often a form of electronic music or electroacoustic music.Composers who use soundscapes include real-time granular synthesis pioneer Barry Truax, Hildegard Westerkamp, and Luc Ferrari, whose Presque rien, numéro 1 (1970) is an early soundscape composition.
The varying air pressure of sound waves imparts mechanical vibrations to the diaphragm which can then be converted to some other type of signal; examples of this type of diaphragm are found in microphones and the human eardrum. Conversely a diaphragm vibrated by a source of energy beats against the air, creating sound waves.
A pickup is an electronic device that converts energy from one form to another that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through ...
