What are the dangers of noise-isolating earplugs

Many friends who live in dormitories and near the square have a problem, which is that they are disturbed by roommates who play games until late every day and by aunties who dance in the square. Faced with this situation, we usually choose noise-isolating earplugs. Using noise-isolating earplugs can greatly reduce noise and provide us with a quiet environment. However, wearing noise-isolating earplugs for a long time is harmful. Let’s take a look at the dangers of wearing noise-isolating earplugs for a long time.

The disadvantages of wearing noise-isolating earplugs are as follows:

1. Using earplugs may cause earwax to be pushed into the middle ear, which can cause tinnitus, decreased hearing, pain or bacterial infection. Users with excessive earwax should use earplugs more carefully.

2. Many bacteria thrive in warm, humid environments. Earplugs should be cleaned frequently with water and mild soap, but foam-type earplugs are usually disposable after use, and may lose their slow-rebound properties after being soaked in water and dried.

3. When inserting the earplug, the air pressure in the middle ear will increase and push against the eardrum, causing pain. This is because the earplug is inserted too deep. To avoid this danger, please first roll the earplug into a thin shape and insert it into the desired position. Once the earplug is fully expanded, it is best not to push it in any further.

Content expansion:

1. Noise-isolating earplugs (also known as anti-noise earplugs, soundproof earplugs, anti-noise earplugs, and sleeping earplugs) are generally made of silicone or low-pressure foam material or high-elastic polyester material.

2. After being inserted into the ear canal, it is in close contact with the external auditory canal to isolate the sound from entering the middle ear and inner ear (eardrum), achieving the purpose of sound insulation, so that people can get a quiet rest or work or study environment.

3. The earliest earplugs were invented in Europe. According to legend, Scottish fishermen used wax earplugs to resist the lascivious sounds of sea sirens. The earliest earplug products also originated in Europe, and wax earplugs are the most traditional material.

4. Later, due to the continuous research and development of new materials, an elastic material gradually became the mainstream for making soundproofing earplugs. It is the polyvinyl chloride (PVC) foam plastic soundproofing earplug with slow rebound characteristics.
