Although graduation has been a long time, university time is hard to forget. Whenever I see the school, I still think of the brothers who haven't been contacted for a long time. When I was in college, I was catching up with the enrollment expansion. The bedroom was quite tense, so a bedroom was full of arrangements. People are naturally noisy, not to mention a group of passionate youth. The noisy environment will naturally bring some inconveniences. Sleep is one of them. Sufficient sleep is really important for anyone, although I sleep well and have good anti-interference ability. However, a rather wonderful dormitory environment can be a hell for those who do not sleep well. Because we had a classmate in the dormitory and we had a bad night's sleep, but when we were playing games in front of the dormitory before going to bed, he couldn't sleep and naturally complained that we were too noisy and even quarreled... Care about the problem of sleep also affects the friendship of classmates.
I would like to see many people who haven’t had a dormitory before college. Many people may sleep hard in this environment, but others are also normal lives and will be embarrassed to stop it every day. How to do it, plug cotton? Too old and too low, I think earplugs can solve most of the problems.
Take a look at our fresnel earbud goddess.
The most famous soundproofing is the 3M series:
There is such
There is such

This kind of pure soundproof earplugs has the advantages of good sound insulation effect and relatively cheap price; the disadvantage is a single function.
The first one is made of soft rubber or silicone, commonly known as "three sections", with good durability and good sound insulation. However, it is not comfortable to wear, and it is OK to wear work and study. It would be a bit uncomfortable if you wear it all night.
As for the third, the most durable, the best, but the comfort is the worst. For the use of the bedroom environment, let it ignore it ... ...
The focus is on the second, similar to the foam sponge material, soft and elastic (slow rebound), can adapt to a variety of different shapes of the ear canal, rose full. Soundproofing and comfort are good. And it can be stuffed into the ear canal and it doesn't affect the students who sleep on the side.
Aunt often pushes similar products. I bought this one:
Before you wear it, you need to knead it in thin strips so that you can tuck it into the ear canal. Then you open your mouth and grab your ears with your hands to make the ear canal straighter. You can squeeze the finely knitted earplugs into the speed of lightning, and wait for a while. The earplugs are full and open, uh... this world is quiet!
As for the soundproof music type, it is now a lot of in-ear earbuds (big headphones can not wear sleep). Such earplugs are not as effective as the above, but the advantage is that they can produce sounds, such as music. The music sound can cover some noise that can't be blocked by the earplugs, and the actual sound insulation effect is better. And listening to light music before going to bed, but also relaxed nerves, faster sleep. However, everyone must remember that music should not be too loud to avoid affecting hearing.
There is an argument that such in-ear earplugs are more injurious to hearing than open-ended earplugs due to their sealing. However, many people believe that due to its tightness, the sound insulation effect is good. Listening to music in a noisy place requires less volume than an open-type earbud, so it brings less hearing damage. I support this argument because I have tried two types of earplugs on the bus. The same sense of hearing, the open earbuds obviously need to open more volume, and I feel loud because the ambient noise is louder. In terms of music, it is not loud. The in-ear style is much better. I have consciously reduced the volume and can still hear clearly. The premise here is that in-ear style is not the kind of "boom artifact ".
The high-end custom ear models and active noise reduction models in this category are not recommended because of their high price and wearing earplugs to sleep. It is very easy to damage the earplugs. Students who have sufficient budgets should look at Aunt’s various recommendations and originals, and introduce a lot of articles on customization and active noise reduction.
Its implementation is in ear earplugs for many phones:
X7 sent
Sony Ericsson X2
However, these types of earplugs with silicone sleeves are simple three-piece models that do not achieve the best sound insulation.
Let's take a look at my set of DaTan TITAN, which is known for buying accessory earbuds:
So many, there is always one for you.
Because this article recommends noise and sleep earplugs, so pay attention to the size of the headset unit when buying. Multiple units of high-priced goods are cautiously selected. One is that the ear plugs are too large, and the side sleeping is stressing the ears; the second is the price is too expensive, and the sleepiness is distressed. For example, the following goods:
Therefore, when people buy soundproofed earplugs, they can buy a compact and inexpensive product with sound quality and decent value.
For example this:
For example, my appointment and current position:
He took office: I3C, an early generation Dasheng. Headphones scarred it, so I said not to buy too expensive is not empty talk, but the actual experience of blood and tears.
Evolution I5c
Current position: DaTan Titan
With this kind of soundproof earplug, under the best sound insulation, the keyboard sound of about 2 meters is completely inaudible. When the ears are wearing earplugs, the sound that can be heard is basically from the solid conduction (stethoscope effect). The soundproofing effect is still guaranteed, as long as we do not deliberately search for the source of sound, we can say that it is completely soundproofed in a normal indoor environment, and people who are not sensitive to noise should be able to fall asleep smoothly. For me, sleeping and taking it out during the middle of the night to remove my urine did not cause much discomfort.
There is also wearing, pure earplugs worn for a long time, the hearing will be abnormally sensitive, may hear their heartbeat, blood, bone sound. This is a normal phenomenon and it is good to adapt; music-based ones do not have this problem.
The article looked and suddenly disappeared.
