Five contraindications to using MP3
In some places abroad, some experts also pointed out that the use of MP3 is an important factor in the disease. The random use of MP3 can even cause young people to be deaf 30 years earlier than the previous generation. Here we will introduce the five most important taboos that must be paid attention to when using MP3 according to some information on the Internet. and propose corresponding solutions for you.
Taboo 1: Adjusting the volume too much
Many users always like to hear MP3 clearly, if possible, turn the volume up as much as possible Turn up. In general, the maximum volume of MP3 can be as high as 80 decibels, which is equivalent to the sound of a lawn mower, which can directly damage hearing. The distortion caused by adjusting the MP3 volume to a high volume will make the treble harsh, the midrange unclear, and the bass muddy, and the distortion is a kind of noise, which will also cause certain damage to your MP3 and headphones.
It is strictly forbidden to adjust the volume to the maximum when listening to MP3
Suggestion: The total volume of MP3 should be controlled at 1/4-1/3 of the maximum volume. Also, make it a habit to turn the volume control knob all the way down after every time you listen to music.
Taboo 2: Listening for a long time
When some users listen to MP3, they always like to listen to their favorite songs once. Listening to MP3 should pay attention to the combination of work and rest. Listening to MP3 for a long time will cause excessive pressure on the ear and overload the ear, resulting in hearing loss and damage to health.
Long time listening is prohibited
Suggestion: Generally speaking, the length varies according to the type of MP3 music you listen to. Overly intense music, such as rock, fast pop, large dynamic symphony, etc., should take a break for about an hour, that is, listening to a CD should take a break of about 15 minutes. Light music, vocals, slower pop music, etc. can take a break every 100 minutes or so. Of course, the time varies according to the earphone equipment. The time mentioned above is the length of the standard earplug. The closed earplug inserted into the ear canal should reduce the time by 20%, while the earphone can appropriately increase the time by about 15%.
Taboo 3: Listening with earplugs
The earphones with MP3 configuration are directly inserted into the ears, which can increase the sound signal by 9 decibels for a long time It can cause damage to the eardrum. And in order to pursue strong low frequency, many earplugs use long flute-type bass resonance and anti-leakage design, and match the shape of the earplugs with the shape of the ear, so that the earplugs are close to the ear canal, and the ear canal is directly used. As a bass resonator, so you can hear more powerful music.
Technically speaking, this is of course a clever design, but the damage it brings to the ears is extremely serious. In short-term use, due to the repair function of the human body, the impact is not large. But long-term use will undoubtedly cause serious hearing damage. Now some manufacturers try their best to meet the preferences of domestic consumers, and now they have launched so-called “extra bass” earplugs, which use a convex film to concentrate the sound energy and aim at the ear holes to increase the low frequency effect. Using these earplugs will undoubtedly cause more serious injuries.
Don’t listen with earplugs
Suggestion: Headphones are obviously much better than earplugs, which is why Walkmans sold in Europe have Part of the reason for having over-ear headphones, because earplugs used to hurt young people in Europe.
Tab 4: Listening to MP3 in a noisy environment
Listening to MP3 on the bus has become a habit of many people, but listening to MP3 in a noisy environment The damage caused is the most serious. According to common sense, anti-leakage earplugs should be used in noisy environments, so as to avoid the intrusion of most noises and hear clear sounds at lower volumes. However, wearing such earplugs can also damage the ears, which may cause poor blood circulation, tinnitus, necrosis of inner ear hair cells and even damage to the auditory nerve.
But using non-closed earbuds or headphones in a noisy environment is not a good idea. Because it will make you involuntarily turn up the volume, which will eventually cause the volume to be too loud and damage your ears after a long time.
Forbidden to listen to MP3 in a noisy environment
Suggestion: We try not to listen to MP3 or other Walkman devices in a noisy environment. If necessary, use closed earplugs, but not for too long.
Taboo 5: Casual use of batteries
For MP3 batteries, they are not as precious as notebooks and mobile phones, so consumers are also less likely to use them. more casual. You can charge it whenever you want, regardless of how much power is left in the MP3. The number of times the rechargeable battery is charged is about 10,000 times. Frequent charging will reduce battery life and cause damage to your MP3.
It is forbidden to use the battery at will
Suggestion: use the built-in lithium battery MP3 after purchasing, please use up its own battery, and then carry out 4~ 6 hours of continuous charging (similar to the use of a new phone), which increases the capacity of the built-in battery. When charging, you can use the principle of “deep charge and deep discharge”, that is, fully charge the battery after running out of electricity, and do not charge it when you think it should be charged. In addition, after the MP3 with dry battery is turned off, if it is not used for a long time, the battery should be removed to avoid damage to the machine due to over-discharge.
Music is beautiful, but the health of the body is the greatest wealth, so I would like to remind the friends who are not very careful about the protection of their ears, because the earplugs may damage the ears. It is irreversible, so everyone must take care of their ears when listening to music. Scientific and appropriate listening is the most effective ear protection technology.
