  2. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    Timbre is perceived as the quality of different sounds (e.g. the thud of a fallen rock, the whir of a drill, the tone of a musical instrument or the quality of a voice) and represents the pre-conscious allocation of a sonic identity to a sound (e.g. "it's an oboe!"). This identity is based on information gained from frequency transients ...

    en.wikipedia.org/wiki/Timbre

    In music, timbre (/ ˈ t æ m b ər, ˈ t ɪ m-, ˈ t æ̃-/), also known as tone color or tone quality (from psychoacoustics), is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments.

    Different phonetic realizations of the same phoneme are called allophones.Specific allophonic variations, and the particular correspondences between allophones (realizations of speech sound) and phonemes (underlying perceptions of speech sound) can vary even within languages.

    Sound also resonates within different parts of the body, and an individual's size and bone structure can affect somewhat the sound produced by an individual. Singers can also learn to project sound in certain ways so that it resonates better within their vocal tract. This is known as vocal resonation. Another major influence on vocal sound and ...

    How sounds make their way from the source to the brain. Audition, the process of hearing sounds, is the first stage of perceiving speech. Articulators cause systematic changes in air pressure which travel as sound waves to the listener's ear. The sound waves then hit the listener's ear drum causing it to vibrate.

  7. Sound quality - Wikipedia

    en.wikipedia.org/wiki/Sound_quality

    The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, [2] processing and mastering done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it. [3]

  8. Colors of noise - Wikipedia

    en.wikipedia.org/wiki/Colors_of_noise

    The Federal Standard 1037C Telecommunications Glossary [1] [2] defines white, pink, blue, and black noise. The color names for these different types of sounds are derived from a loose analogy between the spectrum of frequencies of sound wave present in the sound (as shown in the blue diagrams) and the equivalent spectrum of light wave frequencies.

  9. Voice (phonetics) - Wikipedia

    en.wikipedia.org/wiki/Voice_(phonetics)

    There is a hypothesis that the contrast between fortis and lenis consonants is related to the contrast between voiceless and voiced consonants. That relation is based on sound perception as well as on sound production, where consonant voice, tenseness and length are only different manifestations of a common sound feature.
