Foam earplugs are a type of earplug made of polyurethane (PU) material. Polyurethane has good softness and elasticity, so PU earplugs usually feel soft and comfortable to wear while having good sound insulation. These earplugs are very effective in noisy environments and can help reduce outside noise and protect hearing.
Types of PU earplugs
Cordless PU earplugs: This earplug has no connection cord, is simple to use, and is suitable for daily use.
Corded PU earplugs: String corded foam earplug, which is convenient for the user to remove or hang on the neck to prevent loss.
- Polyester rope: it is polyester material string, good flexibility, not easy to break, suitable for long-term use.
- Plastic rope: relatively strong but slightly less soft, usually used for one-time or short-term use on earplugs.
What are the features of PU foam earplugs ?
PU FOAM EARPLUG has the following features:
- Soft and comfortable
- Efficient noise reduction
- Light and portable
- Easy to use
- Good durability
- Anti-allergy
- Affordable
In general, PU FOAM EARPLUG combines the advantages of comfort, noise reduction, and economy, making it a commonly used hearing protection tool in daily life.
Application field of PU earplugs
- Industrial sites: in high-noise environments such as factories and construction sites, PU earplugs can effectively protect workers’ hearing.
- Study and office environments: In noisy environments, the use of PU earplugs can help people concentrate and reduce noise interference.
- Sleep: Many people use PU earplugs to reduce ambient noise at night and help improve sleep quality.
- Travel: On the plane, train, or bus, PU earplugs can reduce engine noise and improve the comfort of the journey.
How to wear PU foam earplugs?
According to the picture, the steps to properly wear PU earplugs are as follows:
- Compress the earplugs: Rub the PU earplugs with your fingers into a tight cylinder shape for easy insertion into the ear canal.
- Straighten the ear canal: Use the other hand to gently pull up the ear, which can straighten the ear canal and facilitate the insertion of the earplug.
- Insert the ear plug: Quickly insert the compressed ear plug into the ear canal, and hold the ear plug with your hand for a period of time, waiting for the ear plug to expand and completely seal the ear canal.
- Check the wearing effect: If the earplugs are worn improperly, the noise reduction effect will be reduced, and ensure that the ear canal is sealed after the earplugs expand and feel comfortable.
By following these steps, you can ensure that your earplugs are worn correctly for optimal noise reduction.
The correct wearing method of PU earplugs can not only improve the noise reduction effect but also ensure the comfort of wearing for a long time.
The suggestions for proper maintenance of PU earplugs.
Clean regularly
Clean the foam earplugs regularly after using many times. You can gently wash the earplugs with mild soap and warm water, then air dry or gently wipe them dry with clean paper towels.
Do not use alcohol or strong chemicals to clean the earbuds, as these substances may damage the PU material, affecting its elasticity and noise reduction effect.
Keep dry
After washing or wearing, make sure the earplugs are thoroughly dry before storing them. A wet environment can easily breed bacteria or cause damage to the earbud material.
It can also be dried in a ventilated place to avoid high temperatures or direct sunlight so as not to accelerate the aging of the material.
Store correctly
When not using earplugs, place them in a clean container or earplug box and avoid contact with dust, dirt, or damp environments.
Try to avoid placing earplugs in pockets or bags at will to avoid deformation or contamination of earplugs.
Replace regularly
Replace the foam earplugs regularly according to the frequency of use. Typically, PU earplugs lose their elasticity after repeated use and can no longer provide effective sealing and noise reduction. If the surface of the earplug appears hard, cracked, or deformed, it should be replaced immediately.
Disposable PU earplugs are recommended to be discarded after each use, and it is not recommended to reuse, so as to avoid health problems.
Avoid over-compression
When using PU earplugs, the compression of the earplugs should be moderate, and avoid repeated excessive compression of the earplugs because it may lead to the deformation of its shape or the decrease of elasticity, which affects the wearing effect and comfort.
Through the above maintenance measures, the service life of PU earplugs can be extended, and the noise reduction effect and hygiene can be maintained.
