Does in-ear earplug affect hearing? How long do you usually listen to it at a time?

In-ear advantages: 1: reduce the interference of external noise on listening to music ~ ~ (that is, in a noisy environment; You can enjoy music at a relatively low volume. ) 2: The closest contact with the ear is achieved. The sound leakage is greatly reduced. This advantage has two directions of utilization; (a) increase the low-frequency texture and sense of quantity; B: increase the expression of musical details) At present, most low-end in-ear earplugs use A, and most high-end in-ear earplugs use B.

Disadvantages of in-ear style: 1: For some people; Wearing in-ear earplugs is a painful thing. Ears not suitable for otitis media ~2: use in-ear earplugs; It may scratch the ear canal. 3: multi-person use; It is easy to cross-infect some germs ~4: the principle of sound production is unnatural ~ (sound production in the ear canal through a small catheter)

What's deep in the ear? What is shallowness? Hehe; There is no standard for this ~ ~ Let me talk about my personal opinion: all catheters and earmuffs belong to deep ears (such as ER4, E4C, etc ~ ~), whereas they belong to shallow ears (such as T 10~ newly developed by OVC).

Features of deep in-ear earplugs: 1: ensure the consistency of audio performance. (This is also the reason why the current high-end in-ear earplugs are deep in the ear. ) for example. Px200, which is what everyone often says; Some people say it has a strong bass, while others say it has no bass. In addition to excluding personal listening preferences. One thing that can't be ignored is that px200 is on ears of various shapes; The sound leakage situation is different. This leads to the difference of everyone's voice ~ ~ ~ but as long as everyone wears px200 on their ears; I believe that few people think it has insufficient bass.

Because ordinary portable headphones and earplugs must make some compensation for the low frequency of sound ~ so; This limits the improvement of their sound quality ~ and deep in-ear earplugs can have consistent sealing effect on different ears.

2. Earplugs deep into the ear can effectively ensure the reduction of external noise and sound leakage ~

3. Deep earplugs stimulate the ear canal greatly ~ ~

4. Health is a big problem ~ ~

Characteristics of shallow in-ear earplugs:

1: Compared with deep in-ear earplugs; Shallow earplugs greatly reduce the influence of external noise ~

2. The cost is greatly reduced. (All kinds of complicated earmuffs and special parts are saved; The earplug sleeve of shallow ear is basically a silicone ring)

Everyone should pay more attention to this problem. Now I have sorted out a pile of information and talked about it with my personal point of view.

1: In a noisy environment; Due to the excellent sound insulation ability; Advanced in-ear earplugs have unique advantages in protecting hearing.

2. Because in-ear earplugs are not naturally pronounced; Listening for a long time will cause damage to the brain nerves. (note; Not the auditory nerve. This is found on the internet. After receiving the sound; The brain will analyze and locate the sound. This unnatural noise will cause brain fatigue. )

3: High-frequency sound hurts the ears the most; The main damage is the auditory nerve. Strong bass mainly destroys the eardrum ~

4. The human body itself will produce all kinds of internal noises (such as the sounds of visceral activity), and a considerable part of these noises are transmitted to the outside through the ears. In-ear earplugs will block and reflect these sounds when used. It is easy to cause tinnitus ~

5: In-ear earplugs may scratch the ear canal; Cause bacterial infection. Thus affecting hearing and ears.

6. The length of human ear canal is generally 2.5~3.5 cm. According to physical knowledge. When the ear canal length d=(λ/4)+(kλ/2). Can cause ear canal ringing ~ in general; The frequency of sound waves causing ringing is between 2500 Hz and 3300 Hz. In-ear earplugs shorten the ear canal; The frequency of sound waves causing * * * will increase to 4000~5000Hz. Note that the sound in this frequency band is the most harmful to the ears! ! [λ is the wavelength of sound waves; k=0、 1、2、3……]

Conclusion:

1: Listening to high-end in-ear earplugs at a proper volume for a short time (no more than 1 hour) will not cause great harm to hearing.

2. Wearing in-ear earplugs for a long time (with or without sound) can easily cause tinnitus.

3. Earplugs with low-end shallow ears and bass as selling points = ear killer

4. Using sound-proof in-ear earplugs in too noisy environment can protect ears.

5. It is strongly recommended that users of in-ear earplugs pay attention to personal hygiene; Don't cross use.
