How can you reduce or block the sound, and how can you block the sound outside the window

Sound originates from vibration, passes through the transmission medium, and enters the sound sensing organs (microphones, and other sound perceptions) to block the propagation of sound. The propagation of sound is the transmission of vibration, and the transmission of this sound wave should be blocked. It is possible to remove the medium of propagation, e.g. sound is not transmitted in a vacuum, but in reality this method is not easy to implement, so there are other methods:

Instead of blocking the propagation of sound waves, they weaken sound waves to about zero, such as soundproof glass.

Hello dear, I'm glad to serve you, and will try to help you answer it!How can I block the sound outside the window I rent a house outside, leaning on the side of the road, the sound of the car is too noisy, every day is like this, sometimes two or three o'clock there are people walking, too noisy, can only close the window, the sound is a little smaller, put on the mobile phone to listen to the song you like, put on earplugs to put the sound small, unconsciously fell asleep, so that I am now used to playing eggplant, I can't sleep without listening to the song Dear I hope mine can help you, if you are not clear, you can continue to ask, no need to end the consultation, I will answer for you as soon as possible, if you feel satisfied you can help give a 5-star like, your satisfaction in front of the hall is my biggest motivation, thank you!

Effectively isolating noise requires a few measures to help you work, rest, or relax in a quiet and tranquil environment. Here are some ways to do it:

1.Soundproofing materials: The use of soundproofing materials, such as soundproof wall panels, soundproof floors, soundproof windows, etc., can effectively reduce the interference of external noise.

2.Earbuds or headphones: Wearing earbuds or noise-cancelling headphones can block out external noise and allow you to focus. Noise-cancelling headphones can reduce the distraction of ambient noise through technology.

3.Adjust the layout: Rearrange furniture, equipment, and workspaces to keep noise sources away from your activity area.

4.Curtain and window sealing: The use of heavy curtain and window seals can reduce the penetration of outdoor noise.

5.White Noise Machine: Using a white noise machine or mobile app can create a continuous background noise to help mask other noises.

6.Timing: Schedule time for work, rest and play to avoid noise spikes, or to concentrate work during times when there is less noise.

7.Indoor plants: Some indoor plants can absorb some of the noise from the first celery chain and improve the indoor environment.

Choose the right method for your situation, omit and combine it as needed. Remember, noise isolation is about creating an environment that suits you for work and rest, so choose your method to adjust it to your preferences and needs.

Here are some sleep artifacts that can be used for soundproofing:

Earbuds: Earbuds are a common soundproofing tool that blocks out the noise of the surrounding environment. There are many different types of earplugs to choose from, including disposable foam earplugs, reusable silicone earplugs, and custom earplugs, among others.

Noise Cancelling Headphones: Noise cancelling headphones are a type of headphones with active noise control that can cancel out noise by emitting a sonic wave that is the opposite of the surrounding noise. These headphones can effectively block out outside noise, allowing you to enjoy tranquility while sleeping.

White Noise Machine: The white noise machine can make a smooth and continuous noise, masking other noises and helping you fall asleep. You can choose a white noise machine with different pitch and volume options to suit your personal preferences.

Sleep headphones: Sleep headphones are comfortable over-ear headphones that can transmit **, white noise, or relaxing sounds into your ears to help you relax and fall asleep.

Wall-mounted acoustic panels: If your bedroom walls are prone to noise transmission, consider installing acoustic panels. Acoustic panels can reduce the spread of noise and make your bedroom quieter.

Please choose the right sleep artifact for you based on your personal preferences and needs. In addition, maintaining a good sleeping environment, such as using heavy-duty curtains, carpets, and reducing surrounding noise, can also help improve sleep quality.

1) Sound absorption and noise reduction Sound absorption and noise reduction is a method of controlling the intensity of noise in the propagation pathway. The sound-absorbing effect of an object is universal, and the sound-absorbing effect is related not only to the sound-absorbing material, but also to the sound-absorbing structure chosen. This technique is mainly used in interior spaces.

2) Noise Reduction A muffler is a device that can both let airflow pass through and effectively reduce noise. Mufflers are often used to reduce the noise transmitted at the inlet and outlet of various aerodynamic equipment or along pipes. For example, mufflers are widely used in noise control of internal combustion engines, ventilators, blowers, compressors, gas turbines, and various high-pressure, high-flow emissions.

Different mufflers have different noise reduction principles. Commonly used anechoic technologies include resistive anechoic, resistant anechoic, lossy anechoic, diffusion anechoic, etc.

3) Sound insulation and noise reduction: Enclose the machinery and equipment that produce noise in a small space, so that it is isolated from the surrounding environment, so as to reduce the impact of noise on the environment, this practice is called sound insulation. Noise barriers and enclosures are the two main designs, along with other soundproofing structures:

Acoustic chambers, acoustic walls, acoustic curtains, acoustic doors, etc.

This problem is relatively simple, and there are solutions as follows!

1. Install ventilation holes, this is the most affordable, install a row of ventilation holes between the top of the glass and the frame (professional processing glass is sold in places), which can allow some air to enter the room, and ventilation can be done without opening the window, but there is a disadvantage, that is, this hole is very small and the ventilation effect is poor.

2. I personally think that the best solution is to replace the glass of the window on the road, and install it into a thickened hollow sound and heat insulation glass, the effect is obvious.

3. There is also an auxiliary plan: change the curtains, replace the curtains with heavier ones, and also absorb noise; Laying wallpaper and carpet can have the effect of absorbing noise.

There are 3 ways to reduce noise:

The first is to think of a solution from the noise source, unfortunately, this method is a bit difficult! Unless the municipality re-plans the road.

The second is to start from controlling the transmission path of noise, which can be considered to use sound absorption, sound insulation methods to find a way, like the method downstairs is some feasible methods. The landlord can learn from it!

The third is to consider taking some precautions for the recipient, which is obviously not very applicable.

It is recommended that the landlord still work hard in the second part, install soundproof windows, hang thicker curtains, and usually put a little light ** at home!

It's very troublesome, as long as the window is well sealed, the noise is small, then you can build a compartment.

What things collide with each other and make a small sound? Please record your findings. 2. Group discussion, talk about your own operation activities, which items and whatever.
