Science online How can the human ear differentiate between the sounds
The speed or velocity at which sound travels through a medium is dependent upon the density and the elasticity of the medium. The three important terms that are the basics for understanding the physics of sound are sound pressure, sound power, and sound intensity. Sound pressure is defined as the difference between atmospheric pressure and the.

Sound will also travel through a solid, but in that case the interactions of the particles are different than in a fluid, and the constant that takes the place of tension is a different one: Young's modulus. But the formula looks the same: vsound in solid = Y ฯโโโ (2.1.2) (2.1.2) v s o u n d i n s o l i d = Y ฯ.

Sound is a longitudinal, mechanical wave. Sound can travel through any medium, but it cannot travel through a vacuum. There is no sound in outer space. Sound is a variation in pressure. A region of increased pressure on a sound wave is called a compression (or condensation).

A sound is a form of energy, just like electricity, heat or light. Sound is one of the important senses of the human body. Some sounds are pleasant, and some are annoying. We are subjected to various types of sound all time. Sound waves are the result of the vibration of objects. Let's examine some sources of sounds like a bell.
Sound Waves PASCO
On the atomic scale, sound is a disturbance of atoms that is far more ordered than their thermal motions. In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects ( Figure 17.2 ).

Loudness, Intensity, Pitch and Quality of Sound Teachoo
Sound is a type of mechanical wave or an oscillation of matter. A wave is a disturbance that travels from one location to another in a medium. The key here is that the points in the medium oscillate in place while the disturbance itself travels. For example, consider a wave done by a crowd at a ball game.

Sound. Sound is a vibration or disturbance that travel through any medium by transferring energy from one particle to other and can be heard when it reaches a person's or animal's ear. For example when an object vibrates it transfers its energy to the surrounding particles and makes them to vibrate.These particles again collide with the other.

Sound is a form of energy that transfers through particles of matter as compression waves.Sound waves are longitudinal mechanical waves that oscillate in the direction the wave is traveling.
Amplitude, Frequency and Time Period of Sound Teachoo Concepts
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]

17.2: Sound Waves. Sound is a disturbance of matter (a pressure wave) that is transmitted from its source outward. Hearing is the perception of sound. Sound can be modeled in terms of pressure or in terms of displacement of molecules. The human ear is sensitive to frequencies between 20 Hz and 20 kHz.
