Contrary to the popular belief about the sad fate of the galley slaves, they were not usually put at the oars. Each word is created from a limited set of units of speech — vowel and consonant sounds — phonemes.

Musical pitch intervals are also logarithmic units on a frequency scale, such as octave [log 2], semitonecentetc. Note that in the equal temperament the ratio of frequencies of sounds in perfect fifth 1.

Unlike the piano, which is tuned to equal temperament, the strings of a violin are tuned against each other in intervals of perfect fifths.

At the beks of two sound transmission media, elastic energy can be transmitted by the surface waves of different types. Aristotle, Euclid, Ptolemy and Francis Bacon; source: The sand remains in those areas creating various patterns.

How do they, well, almost perfectly, play together? Different number of phonemes is used in different languages.

Tempo is also an important characteristic of a particular piece. As any wave in physics, sound is characterized primarily by its amplitude and frequency or wavelength, which is the reciprocal of the frequency. However they could not be used to play military music to inspire combatants or to assist in communication in battle because probably no one would hear the sounds of lyres, citterns, lutes and harps on the battlefield.

A base log scale is used for the Y axis of the bottom left graph, and escaka Y escal ranges from 0. Recomendar esta calculadora de equivalencias: Scientific substantiation of this phenomenon dissonance was given by the German scientist Heinrich von Helmholtz, who introduced the concept of a natural scale and overtones. Depending on the poetic style, in poetry, syllables of certain length, stress and strength are put together in an orderly fashion. Density, elasticity and temperature of the medium, in which the sound travels.

For classical and Western music, this system that divides the octave into 12 parts, all of which are equal on a logarithmic scale, is the most common for the past several hundred years. Now, if they do not use a tuning fork, musical instruments in orchestras are tuned to a oboe not only because escalw historical reasons, but because oboe tuning is considered very stable.

Then, most probably, wind instruments appeared, as obvious evolution from seashells and horns of hoofed animals, from a simple whistle or a pipe made of a piece of hollow cane or a green willow twig to modern flutes, oboes, trumpets, saxophones and organs. However, humans relatively poorly distinguish sounds by their loudness. A sound-absorbing screen is sometimes used to reduce beld reflections from the walls behind the microphone. This hinders communication and understanding.

Logarithmic scales of measurement Non-Newtonian calculus. Logarithmic scales are also used in slide rules for multiplying or dividing numbers by adding or subtracting lengths on the scales. This was corrected by Pierre-Simon, marquis de Laplace who considered the process of sound propagation as an adiabatic process.

Their originals existed in the form of oral poetical speech. Humans cannot hear infrasound like elephants nels whales or ultrasound like dolphins and bats. A closer geographically and historically examples are European literary monuments: In addition to these characteristics of music sounds, there are specific musical terms that describe the performance techniques staccato and legatowhich affect the perception of music.

If both the vertical and horizontal axes of a plot are scaled logarithmically, the plot is referred to as a log—log plot.

Before the advent of computer graphics, logarithmic graph paper was a commonly used scientific tool. Scientists estimate the distribution of information received by humans through various channels approximately as follows: The plates of the violin body have a number of resonances, that is, they vibrate more easily at certain frequencies and enhance string vibrations A significant contribution to the development of physiological and musical acoustics was made by the outstanding German physicist, physician, physiologist, psychologist and acoustician Hermann Ludwig Ferdinand von Helmholtz.

When sound, like any other wave, is passing through a medium with non-uniform variable characteristics, it can be refracted, reflected, focused or scattered. Chladni figures To make this experiment we need an audio frequency generator or a computer with an application to generate sound signals, an audio amplifier, an electro-acoustic transducer loudspeakera rigid metal plate and some sand or other sand-like material sugar, chalk, flour, semolina. We are talking about poetry, of course.


The propagation of sound is determined by four factors: Some animal species are able to hear well beyond the hearing range of humans. Many people cannot live one minute without music and scientific studies show that music addiction is as real as drug or sex addiction.

The top left graph is linear in the X and Y axis, and the Y-axis ranges from 0 to Owls, foxes and cats can hear the action of tiny little animals like mice on much greater distance than humans can do because they make their daily diet.

Logarithmic scale

The viscosity of the medium. Wikipedia People were interested in how the sound propagates, how it can be recorded and in other features of sound since time immemorial. In addition, diffraction is possible around objects if their sized is comparable or less than the wavelength of the sound waves.

An example of such waves is ripples spreading out when a stone is dropped into water. It should be noted that there is no movement of particles of the medium; the particles just oscillate relative to their equilibrium position. This has the interesting property that as the scale grows to infinity, logarithmic addition converges to maximum. In this system, the frequencies of sounds related to each other by the ratios of small whole numbers octave — 1: Music Judging by archaeological finds of primitive musical instruments, music accompanied modern humanity since its evolving betweenandyears ago in Africa.

Indian system divides the octave by 22 unequal steps, therefore the Indian traditional music sounds strange to the Western ear.

Logarithmic scale – Wikipedia

Helmholtz explained their appearance by non-linearity of the mechanical ebls of the human inner ear. Due to the fact that the sound can propagate only through the material environment, the sound in gaseous and liquid media as well as in plasma is transmitted in the form of longitudinal waves of compression and expansion.

Another reputable Greek scholar Aristotle suggested the finiteness of the speed of sound in air.
