Short animal sounds examples
Intensity: to indicate musically whether a sound is loud or soft, we use the intensity shades, Italian terms whose abbreviations are usually written below the staff. When you want the intensity to change gradually, you use the regulators, signs that indicate that the intensity increases or decreases progressively.
When a body vibrates, i.e. when we hit it or shake it, it emits waves that are transmitted through the air to another medium until they reach our brain through the ear, which is where we actually perceive the sound. Although our eyes do not pick up these vibrations, sound is a physical phenomenon that can be measured and analyzed with a series of special devices. If we try to talk underwater there is a big difference to how we talk out of the water, this is because the waves are transmitted through the air at a speed of 340 meters per second, while in the water they do it much faster, at almost 1500 meters per second. Thus, whales and dolphins communicate perfectly at distances of up to 30 kilometers. Sound waves have different characteristics depending on the height, intensity, duration and timbre of each sound, so for example a body that emits a high-pitched sound vibrates faster than one that emits a low-pitched sound. The frequency of vibration of such movement is measured in Hertz (Hz).

A sound wave is a succession of compressions / dilations of molecules. In this animation, it is observed that the molecules vibrate around their equilibrium position and do not move much, only a few micrometers.
This animation shows the float (plug) moves at the mercy of the perturbations (waves), but always returns to the primitive position. The same principle applies to sound waves: each molecule oscillates around its equilibrium position.General characteristicsMost often a sound wave is a longitudinal mechanical wave, as the molecules move parallel to the direction of wave propagation. In solids, there may also be transverse components.In addition, when the sound wave is transmitted in a homogeneous, isotropic, unobstructed medium, the wave from an ideal source would propagate identically in all directions, it is called spherical. However, at a significant distance from the source, the sound wave can be assimilated to a plane wave since the wave front (set of molecules oscillating in the same vibrational state) tends to be rectilinear. As an example for comparison, the planet Earth is round but, nevertheless, on a human scale it is flat.PeriodThe period, which is labeled T, is the time interval that exists between two successive identical vibrational states of a point in the medium in which the wave propagates.
Is the sound of the flute long or short?
Do you recognize the difference between a long and a short sound? A short sound can be produced by snapping your fingers. On the other hand, if you slowly rub one object against another you can produce a long sound. This quality of sound is known as duration.
Pitch is the quality that allows us to distinguish between a high-pitched sound and a low-pitched sound. The timbre of a sound is the quality by virtue of which we can distinguish two sounds of equal frequency and intensity emitted by two different sound sources.
The blow produced by a hammer maintains a temporal interval (duration) in which the sound persists without discontinuity…. The noise produced by the blow of the hammer is distinguished by the quality of the sound corresponding to:
Intensity It is the quality that allows us to distinguish between loud or soft sounds. In addition to the amplitude, the perception of intensity is influenced by the distance of the sound source from the listener and the listener’s hearing ability.
The sound of the whistle is long or short
In physics, sound is any phenomenon involving the propagation of mechanical waves (whether audible or not), through a medium (fluid or solid) that is generating the vibratory motion of a body.
Sound propagation involves energy transport without matter transport, in the form of mechanical waves propagating through a solid, liquid or gaseous elastic medium. Among the most common are air and water. Sound, sound waves, do not propagate in a vacuum, unlike electromagnetic waves. If the vibrations occur in the same direction in which the sound propagates, it is a longitudinal wave, and if the vibrations are perpendicular to the direction of propagation it is a transverse wave.
Certain characteristics of fluids and solids influence the sound wave. That is why sound propagates faster in solids and liquids than in gases. In general, the higher the compressibility (1/K) of the medium, the lower the speed of sound. Also density is an important factor in the speed of propagation, in general the lower the density (ρ), all else being equal, the lower the speed of sound propagation. The speed of sound (v) is related to these quantities by the formula:
