The definition is also sometimes extended to include sounds made by humans in a directly biological way. For instance, music that is created by the brain waves of the composer can also be called biomusic as can music created by the human body without the use of tools or instruments that are not part of the body ( singing or vocalizing is ...

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 ...

Sounds used by animals that fall within the scope of bioacoustics include a wide range of frequencies and media, and are often not "sound" in the narrow sense of the word (i.e. compression waves that propagate through air and are detectable by the human ear).
His sound recordings were acquired by the BBC and established the BBC's library of natural history sound. [3] He never lost his strong German accent. [3] His work was parodied by Peter Sellers. [3] Koch retired in 1951, but continued to make expeditions to record wildlife sounds, visiting Iceland when he was seventy-one.
Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. "Vocalizations" in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx) as opposed to by the lips, teeth, and tongue, which require substantially less motor control.

The intensity range of audible sounds is enormous. Human eardrums are sensitive to variations in sound pressure and can detect pressure changes from as small as a few micropascals (μPa) to greater than 100 kPa. For this reason, sound pressure level is also measured logarithmically, with all pressures referenced to 20 μPa (or 1.973 85 × 10 ...
