More and more people are used to stay up late.In order to ensure the quality of life during the day.In order to ensure normal work and study during the day, extending sleep time can only make up for it through sleep quality. So how to have a good sleep quality? First of all, you need an environment suitable for sleep. A quiet and no light environment is the best environment for sleep. In addition to the necessary eye masks to block light, earplugs are also needed to isolate external sounds. According to analysis, the sound intensity suitable for sleep is about 15-35dB, and if it exceeds 40dB, it will interfere with sleep. The newly developed double-color foam earplugs have a noise reduction of 38dB. And its soft and comfortable characteristics are very suitable for wearing during sleep.
The difference between double-color foam earplugs and traditional monochromatic foam earplugs
Their noise reduction decibel values are the same, but double-color foam earplugs are more popular than traditional monochromatic foam earplugs. The two-color design is more beautiful, and most of the earplugs on the market are traditional monochromatic earplugs. The noise reduction effect is the same, double-color earplugs sell better than traditional monochromatic foam earplugs. While focusing on product performance, Eastragon also made detailed requirements for the appearance of the product. At present, our double-color earplugs are divided into the following colors:
Lemon yellow and white mix, as refreshing as mango mousse cake;
Sakura pink and white are mixed, which is the favorite color of ladies;
Light blue and white are mixed, and the cross section of the earplugs is as blue as the sky.
We will also develop other mixed color earplugs. If you have custom requirements or better ideas, please feel free to contact us.
Double-color foam earplugs noise reduction principle
Sound is different sound waves produced by vibration. There are many ways to reduce noise. One is to cut off the source of noise from the source; the other is to block the sound transmission during the transmission process. The noise reduction principle of earplugs is to block sound transmission during transmission, because of the porous nature of foam earplugs. The sound will be absorbed by these holes. Just like the soundproofing material for decoration, it is also porous and fluffy. The sponge is soft and will not cause any adverse reactions in direct contact with the skin, which lays the foundation for the sponge as a raw material for earplugs. And Eastragon’s earplugs use memory foam, which has the characteristics of slow rebound. After being rubbed, it is inserted into the ear canal for sufficient time to wait for its slow rebound, which is easy to wear.
Life of double-color sponge earplugs
Foam earplugs are disposable earplugs. Generally, it is not recommended to wear them more than 3 times. Wearing it for many times is easy to cause bacteria to grow on the earplugs, and the earplugs will also lose slow rebound, and the noise reduction effect will be worse. Therefore, it is not recommended to wear earplugs more than the above words. It is best to use it once. The price of sponge earplugs is not high. Compared with silicone earplugs that can be used multiple times, the noise reduction effect of sponge earplugs is also the best.
