ETYM AS. claeg; akin to LG. klei, Dutch klei, and perh. to AS. clâm clay, Latin glus, gluten glue, Greek gloios glutinous substance, Eng. glue. Related to Clog.
Very fine-grained sedimentary deposit that has undergone a greater or lesser degree of consolidation. When moistened it is plastic, and it hardens on heating, which renders it impermeable. It may be white, gray, red, yellow, blue, or black, depending on its composition. Clay minerals consist largely of hydrous silicates of aluminum and magnesium together with iron, potassium, sodium, and organic substances. The crystals of clay minerals have a layered structure, capable of holding water, and are responsible for its plastic properties. According to international classification, in mechanical analysis of soil, clay has a grain size of less than 0.002 mm/0.00008 in.
Types of clay include adobe, alluvial clay, building clay, brick, cement, kaolinite, ferruginous clay, fireclay, fusible clay, puddle clay, refractory clay, and vitrifiable clay. Clays have a variety of uses, some of which, such as pottery and bricks, date back to prehistoric times.
Soil that is plastic when moist but hard when fired. + prikaži više

Physiological sensation received by the ear, originating in a vibration that communicates itself as a pressure variation in the air and travels in every direction, spreading out as an expanding sphere. All sound waves in air travel with a speed dependent on the temperature; under ordinary conditions, this is about 330 m/1,070 ft per second. The pitch of the sound depends on the number of vibrations imposed on the air per second, but the speed is unaffected. The loudness of a sound is dependent primarily on the amplitude of the vibration of the air.
The lowest note audible to a human being has a frequency of about 20 hertz (vibrations per second), and the highest one of about 15,000 Hz; the lower limit of this range varies little with the person's age, but the upper range falls steadily from adolescence onward.
1. The sudden occurrence of an audible event; SYN. noise.
2. The particular auditory effect produced by a given cause; or
3. The subjective sensation of hearing something; SYN. auditory sensation, noise.
4. Audible vibrations transmitted through the air (or other medium)

ETYM French ton, Latin tonus a sound, tone, from Greek tonos a stretching, straining, raising of the voice, pitch, accent, measure or meter, in pl., modes or keys differing in pitch.
In music, the quality of sound—for instance, different strings of a violin may be able to sound the same note (pitch) given certain fingerings, but each string has a different tone. A tone can also be a plainsong melody; it is also the US term (or wholetone) for a note, an interval consisting of two semitones, for example the interval of C–D.
1. A steady sound without overtones; SYN. pure tone.
2. The quality of a person's voice; SYN. tone of voice.
3. The quality of something (an act or a piece of writing) that reveals the attitudes and presuppositions of the author.
4. A musical interval of two semitones; SYN. whole tone, step, whole step.
5. (Linguistics) A pitch or change in pitch of the voice that serves to distinguish words in tonal languages. + prikaži više

1. To adjust the pitch (of pianos).
2. To harden by reheating and cooling in oil; SYN. harden.
3. To make more temperate, acceptable, or suitable by adding something else; moderate; SYN. season.

Pertaining to sound.
Relating to frequencies within the range of perception by the human ear—from about 15 to 20,000 hertz (cycles per second). See also audio response, synthesizer.
