because sound travels pretty slow. thats why if your in the very back at a rock concert, and you see the drummer hit a drum, and you hear the drum a half a second or so later. in marching band, you want the sound to line up for the audience. to achieve this, listen back, and center. usually the drumline. if your in the audience and it sound discordant, its not your fault.

Amplitude. As the amplitude of the sound wave increases, the sound becomes louder.

A person who uses sound waves to make images of the body is known as a sonographer or ultrasound technician. They operate ultrasound machines to capture images of internal organs and tissues for diagnostic purposes.

What we perceive as "sound" is in fact a neural reaction to changes in air compression that our brains interpret as "sound". Air is compressed by some mechanical action (such as a speaker moving inwards and outwards), and the outer ear acts as a bit of a lens to capture and guide these compressed air waves to the inner ear, where the tympanic membrane reacts to these vibrations by vibrating (like the skin of a drum head, but in reverse - this is why it's called an "eardrum"). This vibration is transmitted to nerves that are very close to the ear, which in turn send electrical nerve impulses to the brain, which interprets these as "sound".

If you think about this for a moment, the question "if a tree falls in the forest, and nobody is around to hear it, does it make a sound?" becomes answerable. If nobody hears it, it doesn't create a "sound", only compressions in surrounding air. For the tree to make a falling sound, someone would have to be present and their brain would have to interpret these compression waves as "sound".

The correct term is the tympanic membrane. It serves as a barrier between the outer and middle ear and vibrates in response to sound waves, transmitting these vibrations to the tiny bones in the middle ear.

Sound waves are not a form of radiation. Radio waves, microwaves, and gamma rays are all forms of electromagnetic radiation that can travel through space. Sound waves, on the other hand, require a medium (such as air, water, or solids) to propagate.

Sound waves are not matter; they are the transmission of energy through a medium such as air, water, or solids. Sound waves are produced by vibrations and travel through the medium in the form of pressure variations that we perceive as sound.

vibrate at its natural frequency. WHS AOEC

Its wavelength increases and its frequency decreases

Sound waves are propagated as compression waves in air (and in other gases). They will be produced by any object vibrating at appropriate frequency. As far as humans are concerned, we can hear frequencies from about 25 HZ up to 15 kiloHz, though the upper register gets less efficient as you age. For music or speech transmission we use a loudspeaker which is some sort of diaphragm actuated by a moving coil which responds to electrical signals in this frequency range, and the diaphragm produces the compression waves simply by moving in and out. Sound waves travel at about 720 mph in air at normal temperature and pressure.

All "waves" are energy. In this case, music is a tremendously complex series of waves caused by air compression of differing frequencies, phase, and amplitude. But they are still waves, caused by movement of the air - basic physics tells you that moving air has force (however small) and therefore energy.

The tranducer/microphone converts the vibrations of the waves into electrical audio signals, the vibrations cause a diaphragm inside the transducer to vibrate which in turns create pulses of current that can be interpreted later as the recorded audio.

that isnt a question...?

Perhaps the question was to be something like: "What is happening when a sound wave bounces off an object and returns in the direction from which it came?"

Answer: The sound is echoing.

Curtains help absorb sound waves, whereas sound waves bounce off solid walls, so a curtained room will be more quiet.

Ultrasound

A measurement equal to one wave per second is one hertz (Hz). It represents the frequency of a wave cycle occurring once every second.

The loudness of a sound is directly proportional to the amplitude or intensity of its soundwaves. This means that the greater the amplitude of the soundwave, the louder the sound will be perceived.

The frequency of sound is only determined by the source. It is constant, regardless of how much you change the speed of the sound (by changing the medium it travels in) or the wavelength. It is also got something to do with the amplitude of the wave for more information put: the amplitude of a soundwave. Into google and will find many more things that will help u.

The walls of Hall auditorium may not be smooth due to the construction materials used, such as textured paint or wall panels, to improve acoustics by reducing sound reflections. The textured surface helps to diffuse sound waves, preventing echoes and enhancing the overall acoustic quality of the space.

The energy in a sound wave is both kinetic and potential.

Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy.

Just as in the spring there is compression and rarefaction, so there is elastic potential energy.

In fact, these two are equal, potential energy = kinetic energy, just like a spring.

Just like in a vibrating spring, the total energy is constant and equal to the average kinetic energy plus the average potential energy.

A howl can sound like something like "Aroo"... It starts like a grumble in the throat, then it begins at a low "arr", then a more high pitch with the "oo". Finally it goes back down to a low sound "ooow".
