Introduction Sound waves are essential to human life, as they are vital in countless aspects of life, such as they are primarily in the dissemination of information. Sound waves are applied in several areas, such as in navigation, tracking of ships, and aircraft with the help of sonar, a device for detecting sound waves. These devices are useful in conducting effective communications. In the field of entertainment too, sounds are used in cassettes, radio and many more. However, it needs to be noted that during the propagation of the sound waves, the waves get reflected, refracted and as well as ... Read More

Introduction Sound refers to a particular form of energy that mainly produces a hearing sense in the ear. Sounds are mainly created because of the vibration of the objects as well as the movement of the air molecules. For example, the sounds that are created from the vocal cords and other sounds are made from the elastic body particle movements. Sound requires a medium, for instance, solid, air or liquid for travelling. For this particular reason, they communicate with each other through the usage of "Communications Carrier Assembly" (CCA) as in space because in space there is no medium to ... Read More

Introduction Sound wave reflection at the barrier as if from the source of imagination at a similar distance behind the obstruction. Sound reflection provides rise to reverberation, echo and diffusion. Distinct surfaces possess distinct powers of reflection as calculated by the reflection coefficient or absorption coefficient. Concave surfaces centre on the waves of sound thereby focusing the sound in particular areas and convex surfaces or shapes generally disperse the sound by fostering good diffusion. It is demonstrated that symmetrically drawn surfaces create symmetrical reflections, as the most prominent instance is the whispering gallery. This sound travels along the cliffs through ...

Introduction The sound waves refer to a simple pressure of air that is mainly created by the monument of the molecules in the air. The vibration of the air takes away the sound from the source that is a specific frequency as well as amplitude. The wavelength is also an exterminator of the sound frequency. Besides this molecule, movement denotes the sound frequency along with the amplitude of the wave of sound. A person can hear the sound with a frequency between 20 to 20000 Hertz. In order to travel sounds need a propagation medium to take away the ... Read More

Introduction The vibration, which is travelling through the air or any other medium in the form of an “audible mechanical” wave, is determined as the production of sound. The sound is produced from a “vibrating body” that can be of any medium: air, water, vacuum or an empty space. This phenomenon can be further explained through the example, that during the drum struck, the flexible membrane of the drum vibrates to produce sound. The production of sound is due to the expansion and compression of air on the other side “membrane that vibrates”. Here, the difference in sound waves found ... Read More

Introduction Sound is created when any material vibrates and propagates through a medium for creating sound waves. It is defined as a form of energy and important senses of the human body. Some vibrations are clearly visible and some are not. The object placed to the vibration distracts the particle's state of equilibrium in a particle media and vibration constantly transfigures from one particle to the other. Vibration is defined as the periodic motion of back and forth of the elastic body's particles or medium. Sound is a sequence of pressure waves, which is transmitted through a compressible medium. What ... Read More

Introduction Human beings have the ability to create the sound that starts with the larynx, the voice box which is in the neck. In the vocal cords, there are several small membranous structures which pass across the larynx. An individual can hear that is produced by the vibration of different objects. For example, by plucking the “strings of a guitar” the surrounding air molecules are vibrated then a sound has produced that hurt the ear. In other cases, when a tight band has stretched the vibration of sound created also produced a sound. The frequency of sound is very important ... Read More
