A famous deaf percussionist, Evelyn Glennie, described sound as "a specialized form of touch".
Sound can travel through solids, such as metal, through liquids, such as water, and finally through gas (usually air!).
If you turn your volume up loud enough you can blow out your speakers because the energy is so great it will literally rip the speaker diaphragm apart.
You have tons of opportunities open to you in terms of education, hobbies, and leisure activities that allow you to express yourself in individual ways.
Have you ever listened to loud music or noise and then noticed a ringing in your ears when you were done? From the study of physics we learn that an object produces sound when it vibrates in matter. Low-frequency waves produce low-pitched sounds (such as the rumbling sounds of distant thunder) and high-frequency waves produce high-pitched sounds (such as a mouse squeak). Sounds audible to the human ear usually range from as low as 20 Hz to as high as 20,000 Hz in a young child (the upper range, in particular, decreases with age). How loud something is, is measured in decibels (dB): a measure of the energy content or power of the waves proportional to amplitude. The decibel scale begins at 0 for the lowest audible sound, and increases logarithmically, meaning that a sound of 80 dB is not just twice as loud as a sound of 40 dB, but has 10,000 times more power! It is very important to know that the human ear differentiate between the sounds that reach it through the different factors which are the sound pitch , the sound intensity and the sound quality . You  should know that the sound pitch is a property by which the ear can distinguish between the rough and the sharp voices .
You know that the sound is described as high pitched or low pitched , where the high pitched sound is sharp ( soft ) , And the low pitched sound is rough ( hard ) . When the sharpness of the voices increases , the level of the voice ( the sound pitch ) gets higher . The sound pitch depends on the frequency of the sound source , And the sound pitch increases by increasing the frequency and vice versa . It is very important to know that the sound intensity is the property by which the ear can distinguish between the sounds either strong or weak . You notice that the shouting is stronger than the whispering , And the drum produces strong sound when it is beaten strongly , and it produces weak sound when it is beaten softly . You should know that the sound intensity at a point depends on the distance between the ear , and the sound source . You should know that it depends on the density of the medium through which the sound travels . It is very important to know that the sound quality ( type ) is the property by which the human ear can distinguish between the different sounds according to the nature of the source even if they are equal in the intensity and the pitch .
You  should know that the harmonic tones are tones that accompany the fundamental tone , But they are lower in the intensity and higher in the pitch , and differ from one instrument to another . When you go to the ear doctor to have your hearing test, you are asked to perform a detection experiment with pure tones.


Examples are shown in the graph (which plots threshold sound pressure level vs frequency) for someone with normal hearing and for someone with hearing loss like that which happens typically with age. Various technologies are designed around the fact that people are insensitive to sounds outside the 20Hz-20kHz range, including telephones, CD players and MP3.
There are other technologies that also take advantage of differences in hearing thresholds. Here's an example of a more complicated sound that is made up of three frequency components. The pinna is the large bit of skin on the side of your head that focusses sound waves into your auditory canal.
When the ossicular chain presses against the oval window, it gives the fluid in the cochlea a good push. Although there are more outer than inner hair cells, most of the ascending nerves from the VIIIth cranial nerve, the auditory nerve, receive their input from the inner hair cells.
About the hair cell movie: The movie shows an outer hair cell which has been patch clamped using a whole cell recording pipette at its basal end. Electron microscope picture of a chinchilla's hair cells after hearing was damaged by acoustic overstimulation. This creates a drop in pressure, which pulls in more surrounding air particles, creating another drop in pressure, which pulls in particles even farther out. We hear different sounds from different vibrating objects because of variations in the sound wave frequency. High frequency pure tones sound like high pitches and low frequency pure tones sound like low pitches. Frequency is expressed in units of Hertz (Hz), which is the number of cycles of sound pressure change per second. For each pure tone frequency, the doctor determines the sound pressure level that is just barely detectable. Notice that for very low frequencies (on the left) and very high frequencies (on the right), the pure tone must have a very high amplitude to be heard. In fact, the MP3 sound format takes advantage of a number of properties of human hearing that were all first demonstrated using detection and discrimination psychophysics. Some companies have, for example, developed devices to make sounds that many adults cannot hear. The graphs on the left plot sound pressure level (SPL) as it varies, increasing and decreasing, over time. For example, the controls on a stereo are designed around the Fourier frequency decomposition. When the short pendulum swings a lot you can draw the inference that there is considerable high frequency, or rapid, alternation back and forth of the stick.
The malleus or hammer (on the left in the EM picture) is attached to the tympanic membrane. This causes a local change in fluid density which propagates through the scala vestibuli, around the outside of the scala media to the end of the cochlea.


These inner hair cells are responsible for capturing what we hear and communicating sound to our brain. The effects of sound damage on the outer hair cells are devastating, as the cells are now missing.
Those air particles in turn move the air particles around them, carrying the pulse of the vibration through the air.
A higher wave frequency simply means that the air pressure fluctuation switches back and forth more quickly.
In other words, we usually do no hear very high or very low frequencies unless they are very high in amplitude. The graphs in the right are called the Fourier spectra of the sounds, and they plot sound pressure level versus frequency.
Adjusting the bass alters the level of the low frequency signals, while adjusting the treble alters the level of the high frequency signals. When the long pendulum swings a lot you can draw the inference that there is considerable low frequency, or slow oscillation back and forth of my hand. At the end of the scala vestibuli, there is a small opening that connects up the two outer scala.
The outer hair cells change their shape and rigidity to control the motion of the basilar membrane, amplifying weak sounds and attenuating loud sounds. The low frequency envelope of RatC is played into the stimulus input socket of the patch amplifier, with a peak-to-peak amplitude of about 100 mV. The next time you go to a loud club or rock concert, consider wearing earplugs or some kind of hearing protection. These air particles then collide with the particles in front of them, which in turn collide with the particles in front of them, and so on. It is a cool fact that any sound signal can be decomposed as a sum of pure tones or frequency components. The hair cell changes length - but at constant volume - because it has a motor molecule in the membrane along the cell sides which responds to membrane voltage by changing area. The Fourier spectrum graph plots the intensities (sound pressure levels) of the separate pure tones that make up (when summed together) the entire sound signal.
The level of air pressure in each fluctuation – the wave’s amplitude – determines how loud the sound is. The Fourier spectrum is essentially a plot showing the amplitudes of swing for each of the pendula.
