Why does conch have a sound?

Question 1: Why is there a sound in the conch shell? When the conch shell is buckled on the ear, you can hear the sound in the conch shell, and you can hear the sound like the tide, which is the sound of intracranial blood flow. Because of the principle effect of vibration.

According to the principle of physics, if the frequency of vibration or sound from the outside of the conch is the same as the natural frequency of the inner cavity of the conch, * * will occur. * * * will amplify the sound. When we put the conch on our ears, we hear this * * * sound, or amplified sound. In fact, it's not just conch, we can also hear the sound of * * * when we put a paper box or an empty thermos bottle to our ears.

I heard it in fairy tales before. It was the sound of waves. Some people even say that this is the sound of ancient waves. Of course, this is just a story. Some people say that this is the sound of air flow, or the wind. This is only a small part. Yeah.

The sound of conch is similar to that of organ, wind instrument and flute. Any sound around the conch, including the rustling of the air outside the conch, will make the air inside the conch vibrate. The vibration frequency that conch can gather and amplify is the same as the natural frequency determined by its inner cavity. Even the faintest sound will be enhanced. Because the air in the conch fluctuates, people can hear the sound like waves. Others say it's the sound of your own blood flowing.

So, so, the sound you hear in the conch is actually mainly from the vibration in the air and the sound of blood flowing in your blood vessels.

Question 2: Why is there the sound of the sea in the conch? I put the conch close to my ear, and I clearly heard the sound of the sea tide from the conch like a ghost. What happened?

Jane said that although many of you may be disappointed at first, what you really heard in the conch was not the sound of the sea, but the noise.

Tiny noise is everywhere in our lives, but because of the excellent brains that you and I have evolved for hundreds of thousands of years, this noise is usually not noticed by us unless the surrounding environment is too quiet. If you want to hear the sound clearly, you need to amplify it. Without using electronic equipment, the right singer can also amplify his voice within a certain range.

Let's do a simple little experiment, pout your mouth into an O shape, and then tap your finger on your cheek or throat. You will hear a sound, expanding or contracting the O-shape or bulging your cheeks. This kind of tapping will produce different sounds. This is a simple Helmholtz buzzer (Helmholtz buzzer was originally shaped as a container with a narrow neck or a small mouth. When it is affected by sound waves, there is a proper opening in the mouth, and the air in the cavity vibrates, which is the basic form of singing cavity.

The conch you get to the ear has a hard and curved inner surface, which is very suitable for reflecting sound. This effect is the same as what you just achieved with your lips. The sound of running water around us, the sound of roommates dragging their feet upstairs, and the sound of the wind blowing through the leaves outside the window are all amplified and enhanced by the singing cavity of conch, which becomes clearer and finally can be noticed by our auditory system. And just like we drum our cheeks, conch with different shapes will amplify the sound of a specific frequency, and the sound we hear will be different every time.

As for why it sounds like the sea, alas ... it's a coincidence. You can hear similar sounds with any Helmholtz buzzer, which has nothing to do with whether the buzzer comes from the seaside or not. Find a cup and put your hand on it. The sound you hear through the gap is the same. Of course, you can also use a classic thermos.

Question 3: Why does conch have the sound of sea wind? The air inside the conch vibrates because the external sound vibrates the conch wall and makes a sound similar to the sea wind. If you are outside in a quiet place, you can't hear the sound of the sea wind.

And in any way, there will be the sound of the sea wind in the space next to the ear. You can try to put your hand near your ear, or buckle the cup on your ear.

Question 4: Why can conch make the sound of the sea? Many people will put conch close to their ears to listen to the sound of waves there. This special phenomenon can be explained as follows: the sound from the surrounding environment makes the air in the conch vibrate at the frequency of * * * *. With the increase or decrease of these frequencies, the listener will have an auditory illusion, as if listening to the sound of the waves.

Question 5: Why does the conch make a whirring sound when put in the ear? This is a physical phenomenon called * * * vibration and * * * ringing.

According to the principle of physics, if the frequency of vibration or sound from the outside of the conch is the same as the natural frequency of the conch cavity, * * will occur. * * * will amplify the sound. When we put the conch to our ears, we will hear the sound produced after this * * * sound. When you are in a noisy place around, these noisy sounds will shake the air in the conch shell, so when you put the conch to your ear, you will hear the whirring. If you switch to a particularly quiet place, there is little sound coming from around and the volume is too small to make the air in the snail shell vibrate. At this time, you put the conch on your ear and hear the sound of your blood flowing. .

Question 6: Is the sound of conch due to blood flow or the real principle of sea sound in the shell?

1 In fact, we are usually surrounded by various sounds: the wind, the hum of electronic equipment, the sound of cars in the distance, the sound of birds and so on. All these add up to a background sound with a fixed frequency that surrounds us all the time-white noise.

Because white noise is everywhere, our brains will automatically filter it out. Just like the principle of active noise reduction, we usually fabricate the inverse waveform of white noise to eliminate it, so we can't feel the existence of white noise.

3. However, when we put a shell or any similar closed space on our ears, because the external sounds, including white noise, are greatly reduced, and our brain fails to reduce or eliminate white noise in time, what we actually "hear" is only the reverse waveform of white noise in our brain ~

After a while, your brain will adapt to the new background sound and the noise will disappear. It sounds like the sound of the sea because the sound of the sea is mainly white noise made up by the brain.

Question 7: Why does the conch sound? It is the shell of a conch, which is equivalent to a vibrating cavity. Sound waves of a certain wavelength vibrate in it, and the ears feel the sound. In fact, when you put an empty thermos bottle on your ear, you can hear a "buzzing" sound. There is no basis for someone to choose the quality of the bottle liner, and this sound can be heard without heat preservation.

Question 8: Why does the conch make a sound? Because "little snail" blows seagulls and spreads its wings. Snail, Didi blows waves and laughs. The trumpet summons the ship to starve. The trumpet is called ABBA. He will be back soon. Boundless beaches and blue waters. Blow the horn, my heart is beautiful. "

Question 9: Why is there a sound in the conch shell? When the conch shell is buckled on the ear, you can hear the sound in the conch shell, and you can hear the sound like the tide, which is the sound of intracranial blood flow. Because of the principle effect of vibration.
