What is sound? Sound is a wave‚ a pattern—simple or complex‚ depending on the sound—of changing air pressure. Sound is produced by vibrations of objects. The vibrations push and pull on air molecules. The pushes cause a local compression of the air (increase in pressure)‚ and the pulls cause a local rarefaction of the air (decrease in pressure). Since the air molecules are already in constant motion‚ the compressions and rarefactions starting at the original source are rapidly transmitted through

ventricles chambers are separated by four main valves called the atrioventricular (two valves)‚ pulmonary‚ and aortic valves. These valves help create the heart sounds often referred to as “Lub” and ‘Dub”. Thus‚ the Lub sound is the closing of the atrioventricular valve‚ and the Dub sound is the closing of the pulmonary and aortic valve. In this lab‚ we became familiar with the functions of the heart. We also determined

what is a wave? a wave is a disturbance which travels through a medium and transfers energy from one point to another without causing any permanent displacement of the medium itself. if a stone is dropped in a pond or swimming pool‚ ripples or waves are seen spreading on the surface of the water from the point where it was dropped. the water itself does not move in the direction of the ripples‚ but the waves transfers energy from one point to another. there are two major classes of waves ; mechanical

Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color‚ so we are equipped with ears for the detection of sound. We seldom take the time to ponder the characteristics and behaviors of sound and the mechanisms by which sounds are produced‚ propagated‚ and detected. The basis for an understanding of sound‚ music and hearing is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium

Namee: Paul G. Zamora (Homework in Performance Techniques) Sound Waves- A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air‚ water‚ or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration‚ such as a ringing telephone‚ or a person’s vocal chords. The vibration disturbs the particles in the surrounding medium; those particles disturb those next to them

we could ask from our daily life is that how come we can hear? What is it that we hear? Why do we hear it and deaf people don’t? How do we receive any sound? People use sound all the time. We rely on sounds to communicate. Unexpected noises may warn us of danger. The sounds we hear tell us a lot about our surroundings. Many animals also use sound. Even animals that live in water. Since only the very top of the ocean receives light from the sun‚ animals have difficulty using their eyes to find their
