ACOUSTUCS – Part1

ACOUSTUCS – Part1

ACOUSTUCS – Part 1   Propagation of sound. Characterictics of sound waves. Wavefront , acoustic beam. Period and wavelength. Frequency of the sound. Longitudinal and transverse waves. Speed of sound.     As we know, the sound is the sensation caused by the vibration of the flexible body in agile environment. Parts of the agile environment transmit the vibrations through their mutual connection through intermolecular forces. The oscillation of every part of environment spread throughout the agile environment. Distribution of the periodic pressure variation on agile environment called … Read entire article »

Acoustics Part 2

Acoustics Part 2

ACOUSTUCS – Part 2 PHASE CHARACTERISTICS OF SOUND   Initial phase of the signal   This is the position of the body from which it starts its oscillation. It is measured in degrees. If the body has begun fluctuation from equilibrium position, its initial phase is 0. If we deviate it in extremely positive attitude and let him go, the phase is 90. If two strings, membranes, pendulums or air columns begin their movement with a temporary delay to each other, we see a shift … Read entire article »

REFLECTION

REFLECTION

REFLECTION     When the sound wave reaches the boundary of the medium in which it is distributed, can occur more than one process. Part of the sound is reflected. In this reflection the angle of incidence equals the angle of reflection. On the chart  is the angle of incidence, and  – of reflection.       The line perpendicular to the line of separation of the two circles is called normal. The angles of incidence and reflection are measured against it. The normal is the imaginary … Read entire article »

REFRACTION

REFRACTION

REFRACTION     Refraction of the sound is a change in the direction of propagation of the sound wave as a result of a change in the environment. Since the change in the environment leads to a change in the speed of sound, the sound front turns when going into a new environment.   Refraction should not be confused with diffraction, even though in both cases we have a change of direction of the wave. In the first case we have … Read entire article »

DIFFRACTION

DIFFRACTION

DIFFRACTION   Sound waves propagate spherically. For smaller wavelengths and greater distance from the source, we can perceive them as waves with a relatively flat front and a direction perpendicular to it. The ability of sound waves in meeting obstacles to go around them, penetrating into the area behind them, is called diffraction. Without a diffraction the sound would be audible only in a situation of direct sight to the sound source.By the diffraction we can hear sound … Read entire article »

Doppler Effect

Doppler Effect

Doppler Effect   As a rule, the speed of sound in daily life is much higher than our movement. But with faster movement, such as fast moving objects – cars, trains, the relative speed between the object and the listener will affect the frequency of the sound we perceive. Thus, if a sound source is moving relative to the recipient or conversely the frequency of the perceived sound is changed in proportion to the speed of movement. Trains, airplanes – there is … Read entire article »
