Analysis:
The following are four bad habits of listening to MP3, please pay attention to them in daily life!
1. The volume is adjusted too high
The maximum volume of MP3 can be as high as 80 decibels, which is equivalent to the sound of a lawn mower. This sound can directly damage hearing. The distortion caused by turning MP3 to a high volume will cause harsh treble, unclear midrange, and muddy bass, and distortion is a type of noise.
Recommendation: The total volume of MP3 should be controlled at 1/4-1/3 of the maximum volume. In addition, every time after listening to music, develop the habit of turning the volume adjustment knob to the minimum.
2. Listening for a long time
When listening to MP3, you need to pay attention to the balance between work and rest. Listening to MP3 for a long time will cause excessive pressure on the ears and overload the ears, resulting in hearing loss and harming health.
Recommendation: Generally, the length varies depending on the type of MP3 music you listen to. For overly intense music, such as rock, fast pop music, large dynamic symphonies, etc., you should take a break for about 1 hour, that is, you should take a break of about 15 minutes after listening to a CD. Light music, vocals, slower pop music, etc. can take a break every 100 minutes or so. Of course, the time also changes depending on the earplugs and headphone equipment. The time mentioned above is the length of standard earplugs. Sealed earplugs inserted into the ear canal should reduce the time by 20%, while headphones can appropriately increase the time by about 15%.
3. Wear earplugs to listen
MP3 earphones are inserted directly into the ears, which can increase the sound signal by 9 decibels. Over time, it will cause damage to the eardrums. In order to pursue strong low frequencies, many earplugs use long flute-type bass resonance and anti-leakage designs, and match the shape of the earplugs with the shape of the ear so that the earplugs are close to the ear holes and directly use the ear canal of the ear. As a bass resonator, you can hear more powerful music. Technically speaking, this is certainly a clever design, but the damage it causes to the ears is extremely serious. When used for a short period of time, due to the repair function of the human body, the impact is not significant. However, long-term use will undoubtedly cause serious hearing damage. Nowadays, some manufacturers are trying their best to cater to the preferences of domestic consumers. They have also launched so-called "extra bass" earplugs, which use a convex membrane to concentrate the sound energy and aim it at the ear holes to increase the low-frequency effect. Using these earplugs will undoubtedly cause more serious injuries.
Suggestion: Using headphones is obviously much better than earplugs. This is why most of the Walkmans sold in Europe were equipped with headphones, because earplugs were once very popular among young people in Europe. Cause harm.
4. Listening to MP3 in a noisy environment
Listening to MP3 in the bus has become a habit of many people, but listening to MP3 in a noisy environment is the most harmful. Seriously.
According to common sense, you should use anti-leakage earplugs in noisy environments. This can avoid the intrusion of most noises and hear clear sounds at a lower volume. However, wearing such earplugs can also damage the ears, possibly causing poor blood circulation, tinnitus, inner ear hair cell necrosis and even damage to the auditory nerve.
But using non-closed earplugs or headphones in noisy environments is not a good idea. Because it will make you involuntarily increase the volume, which will eventually lead to excessive volume and damage your ears over a long period of time
