Index Chalkboard scraping

Scraping a chalkboard (also known as a blackboard) with one's fingernails produces a sound and feeling which most people find extremely irritating. [1]

  2. Sounds by type

Acoustic resonance

Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies).

See Chalkboard scraping and Acoustic resonance

Applied Acoustics

Applied Acoustics (French: Acoustique Appliquée, German: Angewandte Akustik) is a bimonthly peer-reviewed scientific journal.

See Chalkboard scraping and Applied Acoustics

Blackboard

A blackboard or a chalkboard is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk.

See Chalkboard scraping and Blackboard

Brainstem

The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord.

See Chalkboard scraping and Brainstem

Chalkboard paint

Chalkboard paint is a specialized paint that creates a chalkboard-like coating that can be utilized as a writing surface in the same manner as a traditional chalkboard.

Christoph Reuter

Christoph Reuter (born 28 November 1968) is a German University professor for systematic musicology at the University of Vienna.

Cotton-top tamarin

The cotton-top tamarin (Saguinus oedipus) is a small New World monkey weighing less than.

Delta wave

Delta waves are high amplitude neural oscillations with a frequency between 0.5 and 4 hertz.

See Chalkboard scraping and Delta wave

Ear canal

The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.

See Chalkboard scraping and Ear canal

Equal-loudness contour

An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones.

See Chalkboard scraping and Equal-loudness contour

Fight-or-flight response

The fight-or-flight or the fight-flight-freeze-or-fawn (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.

See Chalkboard scraping and Fight-or-flight response

Frontiers in Psychology

Frontiers in Psychology is a peer-reviewed open-access academic journal covering all aspects of psychology.

See Chalkboard scraping and Frontiers in Psychology

Garden fork

A garden fork, spading fork, or digging fork (in the past also an asparagus fork, the same name as a very different utensil) is a gardening implement, with a handle and a square-shouldered head featuring several (usually four) short, sturdy tines.

Grima

Grima may refer to.

See Chalkboard scraping and Grima

Ig Nobel Prize

The Ig Nobel Prize is a satiric prize awarded annually since 1991 to celebrate ten unusual or trivial achievements in scientific research.

See Chalkboard scraping and Ig Nobel Prize

Journal of the Acoustical Society of America

The Journal of the Acoustical Society of America (JASA) is a monthly peer-reviewed scientific journal covering all aspects of acoustics.

Macaque

The macaques constitute a genus (Macaca) of gregarious Old World monkeys of the subfamily Cercopithecinae.

See Chalkboard scraping and Macaque

Musicology

Musicology (from Greek μουσική 'music' and -λογια, 'domain of study') is the scholarly study of music.

See Chalkboard scraping and Musicology

Nail (anatomy)

A nail is a protective plate characteristically found at the tip of the digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals.

See Chalkboard scraping and Nail (anatomy)

New Scientist

New Scientist is a popular science magazine covering all aspects of science and technology.

See Chalkboard scraping and New Scientist

New World monkey

New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae.

See Chalkboard scraping and New World monkey

Primate

Primates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers; and the simians, which include monkeys and apes.

See Chalkboard scraping and Primate

Psychoacoustics

Psychoacoustics is the branch of psychophysics involving the scientific study of sound perception and audiology—how the human auditory system perceives various sounds.

See Chalkboard scraping and Psychoacoustics

Psychonomic Society

The Psychonomic Society is an international scientific society of over 4,500 scientists in the field of experimental psychology.

Reticular formation

The reticular formation is a set of interconnected nuclei that are located in the brainstem, hypothalamus, and other regions.

See Chalkboard scraping and Reticular formation

Shrillness

Shrillness is a word used to describe the quality of sounds that have a high-pitched, strident, raucous, screeching or harsh character, such as those produced by a trumpet or piccolo, but it can also be used to describe a widely recognised and puzzling phenomenon whereby certain sounds are perceived as psychologically painful or aversive to a degree that cannot be accounted for simply in terms of frequency content or loudness. Chalkboard scraping and Shrillness are sounds by type.

See Chalkboard scraping and Shrillness

Sound

In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid.

See Chalkboard scraping and Sound

Vancouver Sun

The Vancouver Sun, also known as the Sun, is a daily broadsheet newspaper based in Vancouver, British Columbia, Canada.

See Chalkboard scraping and Vancouver Sun

White noise

In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density.
