Who is the real hearing killer behind the headphones?

The hearing crisis brought by the popularity of headphones and walkmans also shows that the main reason is that headphones, especially earplugs, are used for a long time, and listening to more intense music, so what is the real level of the device? What is the culprit causing hearing loss? Because every friend around us is not hearing damage. The author takes you to reveal the veil and see who is the real hearing killer behind the headphones.
Who is the hearing killer?
To be clear, the biggest threat comes from unintentional use of headphones, such as what is the most damaging in listening to music? The answer to this question can be found on the Internet with many different answers. Some friends say that the hearing killer is naturally a low frequency. So, can the low frequency of the sound hit the ear without affecting the hearing? Some friends said that it should be high frequency, too high frequency is the culprit of damage to the auditory nerve, and some friends said that the excessive volume caused hearing damage. In fact, they are all right, but they are all part of the answer to this question. We sum up all the hearing killers in fact, that is, four words - fatigue, overload.
These two words, we separate, say overload; because overload is also a cause of rapid fatigue. As the name suggests, overload is more than the ability to carry, to make an inappropriate analogy, friends who like music or friends who know something about the sound know that when the speaker is overloaded, the worst condition is that the voice coil is burned, and the ear is almost the same. But not so serious, but too much signal, or too much high frequency, low frequency, will cause different degrees of damage to the ear. Fatigue: This is better understood. It must be because the signal input is too long, so that the physiological pressure of the ear can not be alleviated.
How big is the correct sound size?
This problem is also very common, most users say: listening to music, in a quiet place, the sound is small, in the noisy place, the sound is louder, and it is better to maintain a degree that you feel the right size. It is very safe. In fact, this view is very wrong. The human ear is selective to reduce the noise function. In an environment that is too noisy, the sensitivity is greatly reduced under the self-protection mechanism. At this time, the transition improves the volume of the Walkman, although it may be just To achieve the normal feeling of self, the acceptance of real energy may have exceeded the usual ten times of the giant! For so long, the ears will be overwhelmed.
The use of reasonable and occasional occasions can best guarantee your health. If you are happy, you will suffer in the years to come. Dear friends, please cherish your hearing. It is the cost of our HIFI.
