For example, the phrase Another orange would usually be pronounced with a low pitch on the first syllable. However, it can sometimes be pronounced with a high pitch on the vowel A-. Pierrehumbert marks this high pitch also with H%. [7] (A low boundary tone at the beginning of an utterance is usually not marked by Pierrehumbert.)
A pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. "Pitch" is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen, also known as asphalt. At room temperature, tar pitch flows at a very low rate, taking several years to form a single drop.
The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.
Place theory is a theory of hearing that states that our perception of sound depends on where each component frequency produces vibrations along the basilar membrane.By this theory, the pitch of a sound, such as a human voice or a musical tone, is determined by the places where the membrane vibrates, based on frequencies corresponding to the tonotopic organization of the primary auditory neurons.
The sound may be soft or loud, low pitched or high pitched and appear to be coming from one ear or both. [48] Most of the time, it comes on gradually. [49] In some people, the sound causes depression, anxiety, or concentration difficulties. [48] Tinnitus is not a disease but a symptom that can result from a number of underlying causes.
Analysis Utility Branch Dose–response curves: Graph that shows the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time [2]
Pitch can indicate attitude: for example, Great uttered in isolation can indicate weak emotion (with pitch starting medium and dropping to low), enthusiasm (with pitch starting very high and ending low), or sarcasm (with pitch starting and remaining low). Declarative sentences show a 2–3–1 pitch pattern. If the last syllable is prominent ...
