Is it that the louder the sound, the louder the vibration. The quieter the sound, the less the vibra

The magnitude of loudness is mainly dependent on the intensity of the sound and is also related to the amplitude of the sound. The greater the amplitude, the greater the loudness; The lower the amplitude, the less loudness. In addition, loudness is also related to the distance from the emitter, and the closer to the emitter, the louder it becomes.

The sound intensity of a point in space reached by a sound wave refers to the sound energy passing through a unit of time perpendicular to the unit area of the sound wave propagation direction. The unit of sound intensity is watt meter2. For 2000 Hz sound, an intensity of 2 10-12 W2 can be heard, but for 50 Hz loudness.

It takes 5 10-6 Wm2 to hear, and it feels like the two sounds are of the same loudness, but they are twice as different in intensity. For the same frequency sound, the loudness does not have a linear relationship with the increase of sound intensity, the loudness only increases to 2 times when the sound intensity increases to 10 times, and the loudness increases to 100 times to 3 times.

It is the hertz that resonates with the object and causes the object to vibrate, so that as long as there is an object of the same frequency, whether the hertz is large or small, it will vibrate.

Decibels are the vibrations that produce air that cause objects to vibrate.

Quite right. The magnitude of sound refers to the intensity of sound corresponding to the amplitude of the sound wave. The greater the amplitude, the louder the sound and the greater the amplitude of the vibration.

No, the magnitude of your vibration should be the amplitude, and the magnitude of the sound is also related to the frequency!

Yes Generally, the sound we hear is a longitudinal wave, and the louder the sound is, the louder the vibration.

The amplitude of the vibration of the object determines the intensity of the sound. The three characteristics of a sound are pitch, loudness, and timbre. We call the intensity of the sound that can be perceived by the human ear as loudness, which is related to the amplitude of the vibration of the object, the greater the amplitude, the louder, the smaller the amplitude, the smaller the loudness.

The pitch of the sound is called the pitch, and the pitch is related to the vibrational frequency of the object, the higher the frequency, the higher the pitch, and the smaller the frequency, the lower the pitch.

The principle of the vibration of an objectThe repetitive motion of an object around a balanced position. A part or the whole of an object is deformed by a force, and the deformed part has the force to return to its original state. After the applied force disappears, the restoring force causes the deformed object to move to the equilibrium position, and the deformation potential energy is gradually converted into kinetic energy, and when the object reaches the equilibrium position, the deformation potential energy is zero and the kinetic energy is maximum.

Due to the action of inertia, the object continues to deviate from the equilibrium position in the opposite direction to the original deformation direction, resulting in a new deformation, and the kinetic energy is gradually converted into deformation potential energy, and the deformation potential energy is the largest when the kinetic energy is zero, and the distance from the equilibrium position is also the largest. This is repeated to form the vibration of the object.

Yes, the frequencies that can be accepted by the human ear are certain, too high or too low.

People can't hear it, and there is no necessary relationship between pitch and frequency.

The amplitude of the vibration is large, the louder the sound, the faster the vibration speed and the higher the frequency.

The sound is produced due to vibration, and the hearing range of the person is 20Hz 20000Hz, and the generation wave below 20Hz and the ultrasound wave above 20000Hz are inaudible to the person.

Vibration + frequency.

You're just running fast.

Bees have wings that vibrate quickly.

Will buzz you have arms can.

Does it ring?

The higher the vibration frequency, the higher the pitch of the sound, and the greater the amplitude of the vibration, the louder the sound. The louder the amplitude, the louder it is.

There are three characteristics of sound (i.e., distinguishing different sounds).

1. Loudness: 1) The greater the amplitude of the object, the greater the loudness.

2) The closer you are to the emitter, the louder it is.

3) Reduce the dispersion of sound, and also increase the loudness.

2. Tone: It is only determined by the frequency of the vibration of the vocal body, and the higher the frequency, the higher the tone (tone, girls are generally higher than boys).

3. Timbre: There is the self-determination of the vocal body.

No, the higher the amplitude, the louder it is.

Whereas, frequency is only related to the pitch of the pitch.

If a wave has an infinite amplitude and can be heard by the human ear, its decibel count is also infinite.

And it can be heard by the human ear, and the vibration frequency of the wave of the sound that can be heard by the human ear is 20Hz---20000HzWhat is the frequency of the vibration of running like this?

Of course, frequency has nothing to do with amplitude. Back to my profession, I'll give you an example, two years ago, scientists discovered a star that was swallowed by a black hole, relying on fluctuations when it was swallowed. The frequency of this wave is only 3 Hz, but its energy is greater than that of the whole earth.

The louder and louder the sound. The vibration of the object is the action element of the sound, so the greater the amplitude of the vibration, the louder the sound, this vibration can be understood as the acoustic amplitude, that is, the greater the amplitude, the louder the sound, and the stronger the weakness will be.

Characteristics of sound.

1) Loudness: The volume of the sound (commonly known as the volume) that people subjectively perceive is determined by the "amplitude" and the distance between the person and the sound source, the greater the amplitude, the greater the loudness, and the smaller the distance between the person and the sound source, the greater the loudness. (Unit: dB dB).

2) Tone: The high and low of the sound (treble, bass), determined by the "frequency, the higher the frequency, the higher the pitch (frequency unit Hz (Hertz), hertz [url, the human ear hearing range 20 below is called infrasound, above 20000Hz is called ultrasound) For example, the sound of the low end or higher sounds, such as thin strings.

3) Timbre: Also known as the sound product, the waveform determines the timbre of the sound.

4) Musical sound: a regular and pleasant sound. Noise:

From a physical point of view, the sound produced by the sound emitter vibrates irregularly; From the perspective of environmental protection, all sounds that interfere with people's normal work, study and rest, as well as sound deficits that interfere with the sounds that people want to hear.

5) Pitch, loudness, and timbre are the three main characteristics of musical sounds, and people distinguish sounds according to them.

The faster an object vibrates, the greater the frequency at which sound is produced.

The repetitive motion of an object around a balanced position. A part or the whole of an object is deformed by a force, and the deformed part has the force to return to its original state (restoring force, or deformation potential energy).

For example, the elastic force of a solid and the surface tension of a liquid can be used as a restoring force, and there can also be an external restoring force, such as the tension of a string or membrane.

There are three characteristics of sound (i.e., distinguishing different sounds).

1. Loudness: 1) The greater the amplitude of the object, the greater the loudness.

2) The closer you are to the emitter, the louder it is.

3) Reduce the dispersion of sound, and also increase the loudness.

2. Tone: It is only determined by the frequency of the vibration of the vocal body, and the higher the frequency, the higher the tone (tone, girls are generally higher than boys).

3. Timbre: There is the sound body's own decision, such as the sound of the trumpet and the piano is different.

The loudness of the sound is related to the amplitude of the emitter's vibration. The greater the amplitude of the vibration, the louder the sound; The lower the amplitude of the vibration, the less loud the sound.

In addition, loudness is related to the distance of the listener from the emitter. The farther away the sound is, the more divergent it becomes, and the farther away it is from the emitter, the less loud it is!

the larger; The smaller this question is very simple, there are Shenma questions to ask: by the way: the height of the sound is called the pitch and frequency related to the frequency (the speed of the vibration of the sound source is expressed by the frequency) unit:

The quality and characteristics of a hertz (Hz) sound are called timbre. The timbre is different, and its waveform is different Loudness, pitch and timbre are the three quantities that reflect the characteristics of sound, which are called the three elements of sound.

The greater the amplitude of the vibration of the object, the stronger the sound, and the smaller the amplitude of the vibration, the weaker the sound. The faster the vibration frequency, the higher the sound of collapse, and the slower the vibration, the lower the sound.

Amplitude refers to the maximum possible value of the physical quantity of vibration, usually expressed as a. It is a physical quantity that indicates the range and intensity of vibration.

In mechanical vibration, the amplitude is the absolute value of the maximum displacement of the object from the equilibrium position when it vibrates, and the amplitude is numerically equal to the magnitude of the maximum displacement. Amplitude is a scalar quantity, and the unit is expressed in meters or centimeters. Amplitude describes the magnitude of the vibration amplitude of an object and the intensity of the vibration.

In AC circuits, current amplitude or voltage amplitude refers to the maximum value of current or voltage change, also known as the peak value of voltage or current.

In acoustic vibration, the amplitude is the maximum value of the difference between the sound pressure and the pressure at rest. The leakage circular amplitude of a sound wave is measured in decibels. The amplitude of the sound wave determines the sound intensity.

The amplitude of a simple harmonic vibration is constant, it is a constant determined by the initial conditions of the harmonic vibration (initial displacement and initial velocity). The energy of the harmonic vibration is proportional to the square of the amplitude. Therefore, the square of the amplitude serves as a sign of the harmonic vibration intensity.

The amplitude of the stable phase of the strong ignition vibration is also a constant, and the amplitude of the damping vibration decreases gradually.

Amplitude modulation

Also known as amplitude modulation, amplitude modulation, AM (amplitude modulation) refers to a modulation method that makes the amplitude of the carrier change according to the change law of the desired transmitted signal, but the frequency remains unchanged. Amplitude modulation is widely used in cable or radio communications and broadcasting.

Generally, a higher frequency signal is used at the modulation end, and its vibration amplitude changes as a function of the modulation signal, and then countermodulated at the demodulation end.

The advantage of amplitude modulation is that the amplitude information of the low-frequency signal can be included in the high-frequency carrier signal, which is conducive to the propagation of the signal.

Well, it is loudness, and the strength of the sound is called loudness. The unit is decibels (dB), and loudness is also related to the distance from the sound source and whether the sound is concentrated.

By the way, I will also tell you: the high and low of the sound is called the pitch and frequency (the speed of the vibration of the sound source is expressed by the frequency) Unit: Hertz (Hz) The quality and characteristics of the sound are called timbre. The timbre is different, and the waveform is different.

Loudness, tone and timbre are the three quantities that reflect the characteristics of sound, which are called the three elements of sound.
