What to do if the sound downstairs is reversed upstairs?

As long as the walls are strong and the walls don't have too much soundproofing (not a lot of elasticity), the sound from downstairs can easily reach upstairs and be clear.

1. The reason is that the noise is generally divergent to upload.

2. Sound propagates in different substances, and sound waves will gradually weaken. The reason why you can hear the noise upstairs is that most of the sound made by the upstairs when it hits the ground floor, the sound is transmitted directly to the downstairs through the floor, so it can be heard very clearly, but if the sound is not made from the ground, such as the sound of speaking to the downstairs, it will pass through the air upstairs and the indoor air downstairs The sound waves will gradually weaken.

3. In the same way, the sound from downstairs should be transmitted to the upstairs through the floor slab, and it will pass through the ears of the indoor air upstairs on the downstairs indoor air floor.

How does the sound from downstairs reach upstairs? What should I do if the sound downstairs disturbs the people?

If you want to reduce this impact, you can consider replacing your own doors and windows and choose more soundproof doors and windows, which will reduce the noise.

Since the sound downstairs of your house is often noisy, it is recommended that you directly call ** to explain the detailed situation to the property management where your community is located, and let the property management help you go downstairs to reflect with your neighbors downstairs.

You can try to negotiate with the downstairs resident to deal with it, say it well, and if he doesn't listen, he will feedback to the property to deal with it!

Normally, this is due to the fact that the sound travels upwards. Therefore, 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, the room will be due to the principle of resonance, even downstairs, far away from the sound source, we can hear the noise upstairs.

At the same time, the sound is circuitous, and the noise from downstairs can be transmitted upstairs through gaps 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 the noise from downstairs can be transmitted upstairs.

The speed at which sound travels through various types of objects:1. Sound cannot be transmitted in a vacuum.

2. The air at a temperature of zero degrees Celsius is 331 meters per second.

3. The air at a temperature of fifteen degrees Celsius is 340 meters per second.

4. The air at a temperature of 25 degrees Celsius is 346 meters per second.

5. In cork it is 500 meters per second.

6. Kerosene at a temperature of 25 degrees Celsius is 1324 meters per second.

7. Distilled water at a temperature of 25 degrees Celsius is 1497 meters per second.

8. The sea water at a temperature of 25 degrees Celsius is 1531 meters per second.

9. In the ice it is 3230 meters per second.

10. In copper rods, it is 3750 meters per second.

11. In marble it is 3810 meters per second.

12. In the aluminum rod, it is 5000 meters per second.

13. In the iron rod, it is 5200 meters per second, etc.

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.

Summary. Hello dear, glad your question.

In terms of sound insulation, you need to do floor sound insulation and wall sound insulation, and the overall effect will be better.

The noise from downstairs is transmitted to the upstairs, how to insulate the sound.

Hello, dear, I'm glad that your problem is soundproofing, you need to do ground soundproofing and wall soundproofing, and the overall effect will be better.

This is because the sound coming from downstairs is mainly solid, that is, it is transmitted through walls and ceilings.

So we can do soundproofing for these two places.

For example, making a layer of two-centimeter-thick, extruded plastic board can play a good sound insulation effect.
