This is a list of onomatopoeias, i.e. words that imitate, resemble, or suggest the source of the sound that they describe. For more information, see the linked articles. Human vocal sounds Achoo, Atishoo, the sound of a sneeze Ahem, a sound made to clear the throat or to draw attention ...
Noise (economic), in a theory of pricing developed by Fischer Black; Noise (spectral phenomenon), various random or unwanted signals, including acoustic noise Noise, any unwanted sound; Noise (signal processing), including in electronics; Communication noise, factors that impair human-to-human communication
A long list of noise measures have been defined to measure noise in signal processing: in absolute terms, relative to some standard noise level, or relative to the desired signal level. They include: Dynamic range, often defined by inherent noise level; Signal-to-noise ratio (SNR), ratio of noise power to signal power
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
The Latin synonym is "sonic", after which the term sonics used to be a synonym for acoustics [5] and later a branch of acoustics. [5] Frequencies above and below the audible range are called " ultrasonic " and " infrasonic ", respectively.
The symbolic properties of a sound in a word, or a phoneme, is related to a sound in an environment, and are restricted in part by a language's own phonetic inventory, hence why many languages can have distinct onomatopoeia for the same natural sound. Depending on a language's connection to a sound's meaning, that language's onomatopoeia ...
In other words, the signal has equal power in any band of a given bandwidth (power spectral density) when the bandwidth is measured in Hz. For example, with a white noise audio signal, the range of frequencies between 40 Hz and 60 Hz contains the same amount of sound power as the range between 400 Hz and 420 Hz, since both intervals are 20 Hz ...
Because of the nature of onomatopoeia, there are many words which show a similar pronunciation in the languages of the world. The following is a list of some conventional examples: The following is a list of some conventional examples:
