Sound Waves

75

"Sound waves" are basically pressure waves - areas of higher and lower pressure, that propagate as a wave. You must have SOME means to create those pressure changes, and to do so quickly.

It sorta makes it fly and bounce around

Your ear hears every little thing. There is no known reason for that.

I researched this once an there is no known thing.

hope this helps.

A change in temperature will result in a change in the speed of sound. The frequency of a flute organ pipe is proportional to the speed of sound. For example, an increase in temperature will cause an increase in the speed of sound, and hence the pitch of the pipe will go up. A change of about 4oC will cause a change in the pipe's sound frequency of about 1%. That compares with a change of 6% between adjacent notes on the keyboard. Hence such a change would be significant.

The same effect occurs for the woodwind and brass instruments.

They both move energy through a field without moving a substance.

v = fλ

V/f = λ (wavelength)

V = 340ms-1

340/f = λ

In short you need to know the frequency of the particular sound wave to work out it's wavelength. once you know that you plug it into the above equation and you will get the wavelength of the wave.

They get distant and more quieter

A vibration.

You could buy a sound wave measuring device at most hobby shops. You might also find them at shops that carry musical instruments. There are also specialty sites online that carry them.

That depends a lot on the speed. Assume any appropriate speed, then divide the distance by the speed.

So called "White Noise" is purely random.

Noise that you hear that comes from from physical processes almost always has a pattern and is not white noise.

"Sound that is an imitation of another sound" can be an echo, a recording, or an imitation.

The waves that you hear are called sound waves - it doesn't matter whether it is emitted by a trumpet, or by any other object that you can hear.

People in a boat can talk to one another, to communicate.

DA conversion or D-to-A conversion.

Yes and no. For both it depends both on the frequency and dosage received in the exposure. Anything is lethal at high enough dosage!

The vocal folds in the larynx are what cause the vibrations needed for producing speech. If a person's larynx has been removed or their vocal folds are paralyzed, then an external source of vibration is needed to produce the starting sound. Then all they have to do then is to mouth the words just like they did when they could speak.

The velocity of a sound wave in air increases as the temperature of the air rises. This is because higher temperatures cause air molecules to move more quickly, facilitating faster transmission of sound waves. Specifically, the speed of sound in air increases by approximately 0.6 meters per second for each degree Celsius increase in temperature. Thus, warmer air allows sound to travel more efficiently.

The term that refers to something related to sound waves is "acoustic." It is derived from the Greek word "akoustikos," meaning "of hearing." Acoustic principles are applied in various fields, including music, architecture, and audio engineering, to study how sound is produced, transmitted, and perceived.

Leonardo da Vinci did not discover sound waves in the modern scientific sense, but he made significant observations about sound. He experimented with the propagation of sound in different mediums and noted how it travels faster in solids than in air. His studies laid the groundwork for later scientists to explore the nature of sound and its wave-like properties. Leonardo's holistic approach to understanding natural phenomena contributed to the broader field of acoustics.
