To be specific, sound waves represent an end product of the process of speech production and a primary input utilized by a listener to receive the message sent by a speaker. Because sound plays a central role in the process of communication, it is imperative to understand the manner in which it is generated, altered, as well as quantified. Simply stated, a speech generation mechanism incorporates a line of assembly that works by creating basic sounds comprising a variety of combinations of hisses, buzzes, and pops (Tijdeman 2). After that, the sounds are filtered by effectuating the some adjustments to the lips, tongue, soft palate, and many other articulators. To begin with, a sound wave refers to a disturbance of air pressure incepted from vibrations. Specifically, this kind of vibration may be brought about by a guitar string, a tuning fork, air column in a pipe, a reed in a clarinet, steam that escapes from a radiator, the head of a kick drum, vocal cords, a loudspeaker diaphragm, or anything whose vibrations lie within the frequency range that can be perceived by a listener. The value of this frequency varies from 20 toapproximately 20,000 Hz (Stinson 550). Another point to note is that two conditions are needed for the production of sound. The first one as an elastic medium and the second one is vibratory disturbance. The most common kind of the former is air, and the fundamental purpose of the condition is to allow for the propagation of sound vibrations. In asserting that air is an elasticSurname 2medium, the implication is that just like any other form of matter, air tends to return to its initial shape after deformation by force. To gain an understanding of the manner in which sound is produced, it is prudent to perceive air as a medium that comprises a particle collection that is interconnected by the use of springs. These springs denote the restoring forces joined with air’s elasticity. Firstly, when a particular volume of air is undisturbed, the particles consisted in this medium exhibit uniform distribution, and elastic forces only apply to a resting state. The next thing to be noted is that when a vibrating object, for instance, a tuning fork, is inserted in a medium that exhibits elasticity, air pressure is disturbed through a series of reactions (Blackstock 120). As this object proceeds to the right, a particle adjacent to the tuning fork is also pushed to move towards the right. An elastic force is then created between the adjacent particles, and this generates a series ofparticle replacement towards the right direction. This system of displacement of a set of particles is the underlying concept behind the generation of sound.A rarefaction usually follows a compression wave of sound, and they are both propagatedoutwards at a particular velocity. It should be pointed out that the speed of sound changes according to the average density and elasticity of the medium through which sound propagation takes place. However, for air, the approximate figures for velocity and density are 36,000 centimeters per second and 784 miles per hour respectively (Policastro et al. 34). It is also worth to note that the pressure waveform of sound exhibits considerably large values during compression and low values during rarefactions. On the same note, it has been established that sinusoids are a characteristic of sound, and they are sometimes called simple periodic signals. In this name, the term ‘simple’ refers to the fact that only one frequency component exists. In like manner, the periodic pattern connotes the presence of a repeating pattern. In contrast, complexSurname 3periodic sound signals comprise repetitive sinusoidal patterns, and this kind of sound signals must comprise several frequency elements. The nature of sound propagation is dependent on a number of factors. Most importantly, the intricate relationship that exists between the pressure and density of the medium through which is propagated shapes the manner in which sound is generated. However, it is important to note that this relationship is what dictates the speed of sound, and it is influenced by the levels oftemperature existing in the medium. The second element that influences the fashion in which sound is propagated is the movement of the medium under consideration (Miller 130). In particular, if the medium is in active motion, this would either augment or cut down the speed of sound, which is contingent upon the direction in which the sound is moving. For instance, if sound is travelling in wind and the two move in the same direction, the speed of the former would be heightened. If the two move in opposite directions, then the speed sound would be decreased significantly. The next element that shapes the manner in which sound is propagated ismedium viscosity. However, one thing to be noted here is that for a significant number of media, such as water or air, disturbance by viscosity is considered to be negligible. It has been established that sound can be transferred though plasma, gases, and liquids in the form of compression waves, which are also known as longitudinal waves. However, in solids,sound is usually transmitted in the form of transverse waves. To enumerate, longitudinal waves involve the displacement of a medium in the same or opposite direction as the direction in which a wave travels. Longitudinal waves typically produce both rarefactions and compressions when they travel through a particular medium. In contrast, transverse waves involve oscillations that occur in a perpendicular direction to that of wave travel (Blackstock 150). In order to view soundwaves, objects capable of producing it and parabolic mirrors can be utilized. Another salientSurname 4point to be noted is that the energy an oscillating sound wave possesses undergoes back and forthconversion between the extra compression areas and lateral displacement areas.The next aspect of sounds that is worth exploring is its wave properties. In this regard, it should be mentioned that even though there exist several complexities regarding sound transmission, sound is usually divided into two fundamental components in the ears: time and pressure. These are the two divisions that form the basis of all kinds of sound waves because they can be employed to describe every sound a human ear perceives in an absolute manner (Policastro et
