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 ...
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 ...
Sound waves may be viewed using parabolic mirrors and objects that produce sound. [9] The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy of ...
Sound measurement and analysis reached new levels of accuracy and sophistication through the use of electronics and computing. The ultrasonic frequency range enabled wholly new kinds of application in medicine and industry. New kinds of transducers (generators and receivers of acoustic energy) were invented and put to use.

By September 1916, Tucker's new microphones had been supplied to all sound-ranging sections. [6] In 1917, sound-ranging was further developed so that allowances could be made for poor weather conditions, as sudden gusts of wind could cool the wire: the most effective method found was to wrap the devices in several layers of camouflage netting.
