There are numerous ear plug dimensions because several designs exist. Some have dimensions of 1 x 3 x 4, 1 x 2 x 4 and many more. Some plugs have cords so they are longer. Most of these are sold in packs. In this case, it is the dimensions of the box, not the individual size of the plugs that are measured.
These plugs are designed to quiet sounds. Once they are fit into the ears, the noise is muted. They can also protect your ears from water and other substances. There are now several styles to choose from. Aside from the basic plugs, some are made specifically to shield the ears of music artists.
Others are specially made for swimmers so water does not get into their ears. These can also be used when on airplanes, at the target shooting range or when working with power tools.
People who wake easily can put these plugs on when they go to bed. Students who have trouble concentrating can use these as well. These plugs can be useful in canceling or reducing noisy, distracting sounds. You can also use these if you work in loud places.
You can purchase these plugs in drugstores. You can also get them online. Most stores sell these in packs. Most are very affordable.
It is not only the ear plug dimensions that differ, but so are the materials used. Foam or variants of it are very popular. They are soft, flexible and safe. Other materials used are silicone, rubber and plastic. Some manufacturers also use silicone and other composite materials.
These devices are easy to use. Hold the plug and roll it between your fingers. Put the plug in your ear. Keep holding the plug until it fills up the canal. This will produce a seal that will reduce noise.
This can also prevent liquids from getting in the canal. Dust and other particles will also be kept out. To remove, slowly pull the end until it is dislodged from your ear.
Many plugs can be used over and over. These should be washed after every use so infections can be avoided. Even though they are reusable, you should replace them after extended use. Some are made to be used once. This is especially true for those made for utilization on airplanes.
The ear plug dimensions alone do not determine how effective it is. The design and the material used to make them are also factors.
