Upstairs and downstairs, which is easier to hear, upstairs and downstairs, can you hear upstairs?

Only particularly loud sounds and sounds that hit the building directly are easy to spread out and be heard by neighbors.

In fact, otherwise, then the sound downstairs to the upstairs is the height of the floor - the height of the sound source + the height of the human ear, it is to smash things, analyze it! "Instead of moving furniture, our noise in life is usually ** in people's mouths and hands? "Well, obviously the distance of the sound downstairs is much smaller than that upstairs, and after these sounds are emitted, most of the noise generated by our normal daily life can be absorbed and isolated by the building itself.

The obstacle between the upstairs and the downstairs is the same, we can calculate what is usually the reason for the particularly loud sound and the sound of directly hitting the building in our lives, usually the height of the building is about 3 meters. Because the height of the human ear is significantly greater than the height of the sound source. Then the height of this sound source is on the floor, and our feelings in life are usually that it is easier to hear the sound upstairs downstairs, so it can be clearly seen that the distance between the sound downstairs and the upstairs is smaller than that from the upstairs to the downstairs, which is why, that is to say, this is from the way of sound propagation, through the window or floor to the listener's ears, generally speaking, the clarity and size of the sound is usually determined by the distance between the sound source and the listener and the obstacle in the middle.

We all know that sound travels in the form of waves, and generally speaking, the clarity and magnitude of sound are usually determined by the distance between the sound source and the listener, as well as the obstacle in between. The obstacle between the upstairs and downstairs is the same, that is, it is determined by the distance.

Let's go back to your question, analyze it, we first have to look at the position of a large number of sounds in daily life, our noise in life is usually ** in people's mouths and hands, that is, at a height of 1-2 meters from the ground, these sounds are emitted, through the window or floor to the ears of the listener, we can calculate, usually the current building floor height is about 3 meters, then the downstairs sound to the upstairs into the distance is the floor height - sound source height + human ear height. And the distance from the sound upstairs to the downstairs is the height of the sound source + the height of the floor - the height of the human ear. Because the height of the human ear is significantly greater than the height of the sound source, it is obvious that the distance from the downstairs to the upstairs is smaller than that from the upstairs to the downstairs.

So is it possible to say that it is easier to hear downstairs upstairs?

Actually, what we feel in life is that it's easier to hear upstairs downstairs, why is that? In fact, the reason is very simple, our buildings now have sound insulation indicators, that is to say, most of the noise generated by our normal daily life can be absorbed and isolated by the building itself, only the particularly loud sound and the sound of direct knocking on the building are easy to spread out and be heard by neighbors, what is the reason for the particularly loud sound and the sound of directly knocking on the building in our lives? "Phew!

Either move furniture or smash things. Then the height of this sound source is on the floor, which is equal to 0, and the distance from the downstairs is much smaller than that upstairs.

Summary. Hello dear, happy to answer your questions.

As far as I can see, it's easier to hear downstairs.

Under normal circumstances, since the sound travels upwards, what is said downstairs is easy to be heard by the people upstairs, and when the people upstairs speak, the people downstairs cannot hear clearly, and may even not be heard. In addition, when we go to see the house, due to the principle of resonance in the room, even if we are downstairs, far away from the sound source, we can hear the sound of the upstairs talking. "It's a pleasure to help you and I wish you a great day.

Upstairs and downstairs which is easier to hear.

Dear, your question has been received, it will take a little time to sort out the answer, please wait patiently for five minutes, you can also provide more effective information, so that I can solve your problems more carefully, thank you for your patience.

I hope mine can be helpful to you, can you move your little hands to make a fortune and give a thumbs up? Thank you and have a great day! <>

Generally speaking, in an indoor room, sound is transmitted from the top down. That is to say, the sound from upstairs can be transmitted downstairs, and the sound from upstairs can be heard downstairs, especially in buildings with poor sound insulation.

Because all sound sources are directly or indirectly in contact with the floor, and the floor can transmit the vibration of the sound source to the downstairs to drive the air downstairs to vibrate, so that the people downstairs can hear the sound upstairs.

Acoustic propagation. It is transmitted through a medium. Sound can only be produced due to the vibration of the object, and sound is the fluctuation produced by the vibration of matter, which needs to be transmitted by the medium to be heard.

When sound travels from downstairs to downstairs, the source of the sound needs to vibrate the air first, then the air to vibrate the ceiling, and then the upstairs floor to vibrate the air. During this process, the sound propagates through a number of different media, all of which are heavily attenuated.

The sound is circuitous, and the sound from downstairs can be transmitted upstairs through cracks such as windows. We shout in front of the building, and the people in the back of the building can also hear the shouting, which is the roundabout nature of the voice.

The sturdy solid floor slab conducts sound, so that the sound from downstairs can be transmitted upstairs. In ancient times, there was no modern communication equipment such as ** and mobile phones, when the enemy attacked, the soldiers put their ears on the ground, and they could hear the sound of horses' hooves and footsteps of the enemy approaching in the distance, and the solid ground could conduct sound. Similarly, the two sides of a solid wall speak easily and are easy to hear, while the two sides of a hollow wall are blurred.

Sound insulation materials are divided into several categories:

1. Porous materials, which are the most commonly used materials in engineering. Example: mineral wool, glass wool, foam, felt, perlite, etc.

2. Plate-like material. Example: plywood, asbestos cement board, gypsum board, rigid board, etc.

3. Forming ceiling sound-absorbing panels. Example: mineral wool acoustic panels, glass wool acoustic panels, soft fiberboard.

4. Membrane material. Examples: plastic film, canvas, artificial leather. Leather.

5. Flexible materials. Examples: sponges, latex blocks.

Sound is a sound wave produced by the vibration of an object. It is a wave phenomenon that propagates through a medium (air or solid, liquid) and can be perceived by the auditory organs of humans or animals. An object that initially emits vibrations (vibrations) is called a sound source.

Sound travels in the form of waves that vibrate (vibrate). Sound is the motion formed by the propagation of sound waves through any substance.

Generally speaking, I can't hear it, but I've never heard it anyway, upstairs and downstairs. But if it's a quarrel, or if it's a child being beaten or scolded, this kind of voice will be heard if it is particularly high-pitched, so don't do such a thing.

The answer is so dear, I can't hear clearly. The people speaking upstairs are reflected and absorbed in different directions by the structure of the room and the different furniture in the room, and the sound energy that can actually be transmitted downstairs is very small, and the sound will become mixed and blurred. And when the people downstairs speak, the reflection from the ground increases the energy to the room.

In addition, the noise outdoors is generally louder than that indoors. Therefore, people who are outdoors have weaker hearing sensitivity than people who are indoors, so in most cases, people upstairs can hear people downstairs, but people downstairs can't hear or can't hear people upstairs clearly.

Generally speaking, it is not audible, because there is a thick floor between the upper and lower floors, and if this floor is not soundproofed, then you may hear a little sound, but it is not so obvious.

If the sound insulation effect is poor, you may be able to hear only a few words.

If the downstairs is louder, the downstairs can be heard. There is also to see how the sound insulation effect of the building is, anyway, my building can be heard.

This needs to see the situation of the building, generally like small property rights or commercial housing buildings with poor quality can hear the upstairs talking, but the *** house is not able to hear the talk.

If your house is not soundproofed, you can hear the sound of talking upstairs and downstairs, and if you talk loudly.

Now the sound insulation effect of the real estate is relatively poor, if the downstairs is louder, the upstairs can be heard.

Is the sound insulation of your building good? If the sound insulation is poor, it is audible.

Normally, people upstairs can't hear people downstairs, but people downstairs can easily hear people upstairs.

Dear, glad to answer for you! It's easier to hear downstairs upstairs because:1

The sound from the upper floors causes the cherry blossoms to vibrate rhythmically with air molecules, causing the surrounding air to change in a dense and dense longitudinal wave, which produces sound waves. When the sound wave is transmitted downstairs, it will cause a sparse change in the air downstairs, forming a longitudinal and closed differential wave between the dense phases, which will then be transmitted to the upstairs, making it easier for the upstairs to hear the sound downstairs. 2.

A large number of spine sounds are emitted from the mouth and hands of people, that is, at a height of 1 to 2 meters above the ground, and these sounds are emitted and transmitted to the listener's ears through windows or floors. The distance from upstairs to downstairs is less than that from upstairs to downstairs, so upstairs will hear downstairs more clearly.
