How Sound Works

Sound is a complicated idea because it involves so many different factors. The ear processes sound by quickly moving it through the different bones in the ear. For example when a person hears an acoustic guitar, the bones of the ear pick up the sound waves as they travel through the air and process those sounds so the individual hears it. There are also situations where the sound changes, such as with ultrasound technology. Sound is used in different ways and for different things beyond the simple idea of music.

How We Perceive Sound

• Temporal Bone and Ear : explains the bones in the ear and what each one does.
• How We Perceive Sound : describes the process in which the ear picks up sound and processes it.
• Sound-Equalization in Relation to the Way We Perceive Sound : focuses on the way sounds equalize prior to the ear processing the waves.
• Sound : offers a look at how music and science play a role in sound processing.
• Sound is Energy : explains how sound is made and what happens to sound as it moves.

The Physics of Sound

• The Physics of Sound : describes different things the cause sound to change.
• The Nature of a Sound Wave : explains the different parts of a sound wave and what they do.
• Traveling Waves : focuses on the ways that sound waves travel and move.
• Sound Waves and the Eardrum : describes how the ear process sound waves.
• Speed of Sound in the Air : gives the formula that determines the speed of sound.

Applications of Sound

• Applications of Sound : explains different types of sound and how it’s used.
• How Ultrasound Works : describes the way that an ultrasound works and the different properties of it.
• What is Noise Cancellation? : offers a definition and description of noise cancellation.
• Horn Speaker : gives a history of the horn speaker and how it evolved over time.
• Advanced Applications of Sound in Medicine : looks at the way in which medicine uses sound, such as with ultrasounds.

History of Sound/ How Sound Has Progressed

• A History of the Study of Sound : explains how historians documented sound over time.
• The Wave Theory of Sound : focuses on the acoustic side of sound history.
• History of Electricity : looks at how electricity changed the processing of sound.
• The Digital Revolution : offers a look at digital processing and what that did to sound.
• Sound Changes : describes general changes to sound and how it changes due to different factors.

Everything in the world makes sound, from a classic fender strat guitar to a person walking down the street. Technology is constantly evolving and as it evolves, sound is changed. The idea of acoustic music still exists, but today digital and electronic sounds in music are also popular. It’s obvious that sound will keep changing and evolving in the future. Scientists and physicists are always working on new applications for sound in terms of medicine and other areas. No one knows what the future of sound holds, but it will be interesting to see how it continues to change.
