What is the sound insulation effect of earplugs for swimming? Can I sleep with earplugs?

Summary: First of all, earplugs for swimming have a certain sound insulation effect, but earplugs for sleeping are definitely not as suitable as those for real sleeping.

3M earplug is one of the most important products in its hearing protection product line. With its excellent protective effect, excellent wearability and product diversity, it has long occupied a huge share in the earplug market. 3M earplugs are widely used in occupational noise protection to reduce occupational diseases such as hearing loss and noise deafness caused by excessive noise. 3M earplugs are also accepted by more and more people, and are used for hearing protection in places that need to be quiet, such as sleeping and self-study, or when watching noisy sports events (such as F 1 car racing) and participating in noisy entertainment activities.

Foamed earplugs are generally made of PU or PVC materials, which are soft and comfortable and generally have high noise reduction effect. However, this kind of earplug needs some wearing skills. When wearing, you need to knead the earplug body first, and then insert the earplug into the ear canal. Improper wearing will greatly reduce the protective effect. Most foam earplugs are designed to be non-washable and need to be discarded as a whole after being soiled.

Prefabricated earplugs are made of rubber or silica gel and directly inserted into the ear canal, thus eliminating the step of rubbing earplugs, and the wearing method is simple and easy to master. This kind of earplug has good durability and can be cleaned and reused. But its comfort and noise reduction effect are worse than those of foam earplugs.

Friction-free foam earplug is a product between the above two, which has both advantages: the earplug head is made of foam material, which provides good comfort and noise reduction; When wearing, it can be directly inserted into the ear canal without friction, which is convenient to wear.

Suggestions on the selection of earplugs

Choose earplugs with better comfort. The comfort of earplugs is closely related to whether users are willing to wear them for a long time, and enough wearing time is the most critical factor affecting the actual protective performance of earplugs. Generally speaking, foam earplugs and non-friction foam earplugs are softer and more comfortable, and are more suitable for long-term wear. The choice of earplugs is not the higher the noise, the better. If the noise is reduced excessively, users will feel isolated, and too many useful sounds, such as voice and alarm sounds, will be blocked. Therefore, it is suggested that the actual contact noise range is between 75 and 80 dB after wearing earplugs.

Choose earplugs that are convenient and hygienic to wear. Foam earplugs need to be rubbed when worn, which requires high hand hygiene and is not suitable for dirty and greasy environment; The wearing of foam earplugs requires high skills, and users must master the correct wearing methods when using them. Preformed earplugs and non-friction foam earplugs do not need friction when used, which is more suitable for dirty environment and more convenient to wear.

Consider the use cost. Foam earplugs should not be cleaned, and should be discarded as a whole after being soiled and damaged. Prefabricated earplugs can be cleaned and reused with low use cost. The use cost of non-friction foam earplugs is generally high.

When using earplugs when sleeping, it is recommended to use foam earplugs without wires.

When using earplugs for waterproof swimming, it is recommended to use waterproof foam earplugs or prefabricated earplugs made of rubber and silica gel.
