Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing ...
Sound propagates as mechanical vibration waves of pressure and displacement, in air or other substances. [5] In general, frequency components of a sound determine its "color", its timbre . When speaking about the frequency (in singular) of a sound, it means the property that most determines its pitch . [ 6 ]
Pitch is perceived as how "low" or "high" a sound is and represents the cyclic, repetitive nature of the vibrations that make up sound. For simple sounds, pitch relates to the frequency of the slowest vibration in the sound (called the fundamental harmonic). In the case of complex sounds, pitch perception can vary.
Ululation (/ ˌ j uː lj ʊ ˈ l eɪ ʃ ən, ˌ ʌ l-/ ⓘ, [1] [2] from Latin ululo), trilling or lele, is a long, wavering, high-pitched vocal sound resembling a howl with a trilling quality. It is produced by emitting a high pitched loud voice accompanied with a rapid back and forth movement of the tongue and the uvula. [3]
Treble describes tones of high frequency or high pitch, ranging from 6 kHz to 20 kHz, [1] comprising the higher end of the human hearing range. In music, this corresponds to high notes. The treble clef is often used to notate such notes. [2] Treble sound is the counterpart to bass sound.
More important than range in voice classification is tessitura, or where the voice is most comfortable singing, and vocal timbre, or the characteristic sound of the singing voice. [1] For example, a female singer may have a vocal range that encompasses the low notes of a mezzo-soprano and the high notes of a soprano.
Very high; see also in altissimo alto High; often refers to a particular range of voice, higher than a tenor but lower than a soprano alzate sordini Lift or raise the mutes (i.e. remove mutes) am Steg (Ger.) At the bridge (i.e. playing a bowed string instrument near its bridge, which produces a heavier, stronger tone); see sul ponticello amabile
For instance, two recognized sources of high-pitched sounds might be electromagnetic fields common in modern wiring and various sound signal transmissions. A common and often misdiagnosed condition that mimics tinnitus is radio frequency (RF) hearing, in which subjects hear objectively audible high-pitched transmission frequencies that sound ...
