What is the difference between tone and timbre in physics in junior high school?

The second year of junior high school, page 37 of the first volume of the new people's education edition, the question type is exactly the same, it should be 7654321 because when the bottle is struck, the air column in the bottle vibrates, not the water vibrates, the larger the air column vibrates, the higher the vibration frequency, so the more water, the smaller the vibration frequency, so the tone is low, so it should be 754321

I don't know which version of your textbook you are, do I?

The query spacing correlation experiment uses control variables, and the method of controlling variables has been tested a lot, but the line is selected. For example, experiments to explore the factors related to the amount of pressure.

1234567 from left, because the percussion is pronounced by the part of the glass bottle that is not filled with water--- the length of the glass bottle is low pitched. If it is blown, the air column inside the bottle vibrates and makes a sound, and it is also 1234567 from the left. Because the law of vibration sounding is:

The sound source is long and low-pitched.

The bottle is full, the sound is very dull, the scale is naturally low, so it's 7654321 (from left to right).

You can experiment with a glass.

1234567, because the sound of a bottle with less water is muffled, i.e. 1 (dou) and so on should be 1234567

1234567, the air column becomes smaller, the frequency increases, and the pitch increases.

The more water in the bottle, the lower the vibration frequency and the lower the pitch.

The more water, the lower the pitch, and if you blow more water, the higher the pitch. Quite the opposite.

If it's a knock, it's 7654321, it's the water vibrating, if it's blowing, it's 1234567, it's the air column vibrating.

Pitch: Indicates the pitch of the voice. The pitch mainly depends on the frequency of the vibration of the sound source, and we can change its frequency by changing the characteristics of the emitter itself (such as length, tightness, size, amount, thickness), which can affect its pitch.

The human ear's perception of how high or low a sound is called pitch. Tone is mainly related to the frequency of sound waves. The higher the frequency of the sound waves, the higher the pitch.

Timbre and shout: Indicates the quality of the voice. Generally speaking. The sound emitted by different objects is different, for example, the sound of different people shouting is different, and their timbre is different.

Timbre is the characteristic that distinguishes people from two voices with the same loudness and the same tone, or the comprehensive response of the human ear to sound waves of various frequencies and intensities. Timbre is related to the vibrational waveform of the sound wave, or to the spectral structure of the sound.

Nature of sound: 1Pitch:

It is determined by the frequency of vibration. 2.Hours:

The length of time the object is shaking. 3.Strength and weakness:

Determined by amplitude. 4.Timbre:

The pitch of the voice is called pitch.

Tone definition: The faster an object vibrates, the higher the pitch of the sound it makes. The slower the vibration, the lower the pitch of the sound is one of the three main sail bystander properties of sound, namely volume, pitch, and timbre.

It indicates the degree to which a person's hearing can distinguish the tone of a sound. The pitch is mainly determined by the frequency of the sound, but also has to be closed with the intensity of the sound. For pure tonal oak of a certain intensity, the tone rises and falls with the rise and fall of frequency; The pitch of a certain frequency of pure tone and low frequency pure tone decreases with the increase of sound intensity, while the tone of high-frequency pure tone increases with the increase of intensity.

Tone Analysis: Pitch is mainly determined by the frequency of the sound. For pure tones of a certain intensity, the pitch rises and falls with the rise and fall of frequency; Pure tones of a certain frequency

Girls have a higher pitch than boys, but boys have louder voices than girls.

The pitch is related to the vibrational frequency, and the higher the frequency, the higher the pitch, like the sound waves of bats, the higher the frequency. And vice versa, loudness? The magnitude of the sound, the amplitude of the vibration.

Pitch is related to the frequency of vibrations, and the faster the frequency, the higher the pitch. Loudness is related to the amplitude of the vibration, and the greater the amplitude of the vibration, the louder the loudness. Generally, girls speak in a high pitch, and boys speak loudly.

Loudness is the magnitude of a sound, and pitch is the level of the sound, just like a song when you amplify the sound is to turn up the loudness. In life, we say who speaks with a loud voice, that is, his pitch is high, I hope it can help you understand.

Loudness refers to the volume of sound. A big sound can be said to be loud, and a small sound can be said to be a small loudness! Pitch refers to the pitch of the sound. For example, the bark of a cow or a donkey is a low tone, and the sound of a cat is a high pitch!

Loudness refers to the magnitude of the sound and is related to the amplitude (amplitude of the vibration).

Pitch refers to the pitch of the sound and is related to the frequency (how fast or slow it vibrates).

For example, a baritone singer sings loudly in the front (loud and low), and the three sopranos in the back sing softly (loud and low pitch).

Loudness: The magnitude of the sound, which is related to the amplitude of the emitter, the greater the amplitude, the louderness.

Pitch: The pitch of the sound, which is related to the frequency of the emitter, the higher the frequency, the higher the pitch.

Loudness is the magnitude of the sound like snare drums and kick drums.

Pitch is the difference between a bass and a soprano.

Loudness refers to the magnitude of the sound and is related to the amplitude of the vibration.

Pitch refers to the pitch of the sound and is related to the frequency of vibrations.

For example, a mosquito calls a loud voice with a high pitch and low loudness. (You can feel it, the mosquito call is small, but it is very high-pitched).

Whereas the tiger barks, the voice is low in pitch and loud. (The tiger's cry is deafening, but the voice is deep).

Loudness is the magnitude of the sound, like your speaker. It has to do with the amplitude of the vibration.

Pitch is the pitch of the sound, for example, the higher the pitch of the melody, the more vibrations in the same time.

Loudness is the magnitude of the sound, that is, the amplitude of the generator;

Pitch is the number of times a body vibrates per second, that is, the frequency, the higher the pitch, the sharper the sound, for example, a man's voice is low, that is, the pitch is low; A woman's voice is thrier, i.e., low-pitched.

Loudness is the magnitude of the sound, which is equivalent to the volume. (depending on the amplitude).

Pitch refers to the pitch of the sound, just like do rai mi in **. (depending on frequency).

Loudness refers to the magnitude of the sound and is related to the amplitude of the vibration. The louder the louder, the farther the sound travels.

Pitch refers to the pitch of the sound and is related to the frequency of vibrations. The higher the pitch, the harsher the sound sounds.

Loudness is the size of the sound, for example, so-and-so is very noisy. Pitch is the high and low of the voice, such as screaming.

Loudness refers to the magnitude of the sound.

Pitch refers to the speed of the frequency.

I hope to choose it.

Loudness refers to the magnitude of the sound, which is related to the amplitude of the vibration, the greater the amplitude, the louderness, and the distance from the sound emitter.

Pitch refers to the pitch of the sound, which is related to the frequency of vibration, the faster the frequency, the higher the pitch.

Loudness is the amplitude of the vibration, i.e., whether you sound loud or small, while the pitch is high or low depending on the vibrational frequency.

Loudness refers to the size of the voice, refers to the size of the sound we usually say, such as speaking loudly and singing loudly, which refers to the loudness, which is related to the amplitude of loudness and vibration.

Pitch refers to the pitch of the voice, refers to the sharpness and depth of the voice we usually speak, such as boys speak in a business is generally low, girls speak in a general sharp, and the pitch is related to the frequency of vibration.

I hope it can help you, study hard every day!

Loudness is the magnitude of the sound, and pitch is high or low.

Loudness is strength and pitch is high or low.

Eat up the physical characteristics of sound – loudness and timbre.

The three elements of sound: pitch, pitch, and timbre are not very explained in junior high school, because these need to be described by teaching professional signals. Here I will briefly talk about these three elements in essence.

Pitch: refers to the energy of the sound, including loudness and intensity, this is the sum of the energy of all the components of the sound, which describes the sound from a macroscopic perspective, which is relatively easy to understand.

Tone and timbre are not so easy to distinguish, because this involves sound frequency and spectrum, which is relatively specialized, so junior high school cannot describe it too carefully.

Tone: Sound frequency, that is, the number of times the sound changes per second, which is generally for a certain frequency component of the sound, because a sound is usually not composed of a frequency sound, so to describe the sound frequency, it is necessary to decompose the sound into many components of a single frequency sound.

Timbre: refers to all the frequency components contained in the sound, as well as the amount of energy generated by each frequency component, popular understanding, the determination of timbre, is composed of how many kinds of single-frequency sounds, the amount of energy accounted for by each single-frequency sound, and one of the two changes will change the timbre, which is the analysis of the signal from the frequency domain.

Your question, in fact, the pitch has changed, the timbre has also changed, and both are related. As far as the normal feeling is concerned, it is also "the sound is different", and you already know what the sound of broken and unbroken ceramics is, you can judge, not purely refer to the tone or timbre change, you can judge. This question itself is not scientific, so there is no need to delve too deeply.

It can be seen from this that the questioner does not understand the sound at all.

It feels like the tone is more accurate, and bad porcelain and good porcelain have different frequencies and different sounds after being struck, and the same is true for watermelons.

Pitch refers to the degree to which a person perceives the tone of a voice. It mainly depends on the frequency of the sound, and the person's perception of the tone, which increases with the frequency and decreases with the frequency. However, people's subjective perception of tone is not necessarily determined by the frequency magnitude, it is also related to the intensity of the sound.

Timbre, once called a sound product, is people's perception of the sound quality of a voice. There is no timbre in a pure tone, and timbre is spoken of as a compound sound.

The porcelain damage is to look at the tone, the timbre of the watermelon.
