Explain the mechanism of hearing damage in general:
The large volume will damage the hair cells, while the hair cells are non-renewable, one less one, so don’t turn the volume of the headphones too large at any time. However, as long as you listen to a few hours a day at a suitable volume, there is not much problem.
All the headphones are equipped with black magic, these black magic will make you completely inaccurate judgment on the real volume of the headphones!
Black Magic 1: Music noise comes in
Listeners use non-noise-reducing headphones to listen in the outdoors or in the noisy room, often adjusting the volume of the music to “pressed” noise. So when you feel that the volume of music is just louder than noise, it is far beyond what your ears can bear.
You can do a very simple experiment, listen to music on the roadside, adjust to the right volume, and then use this volume to listen at night, you will be very surprised by the volume.
I don’t know, your ambient noise and the louder headphone volume, your poor ears are suffering a double blow.
Black Magic II: The bass treble is fully rolled away
Some earphones deliberately make the bass tone very heavy, but in fact, due to their own quality problems, they are only 50 to 60hz bass, which is less than 40hz. This results in the middle and high-pitched areas being thin and the human voice is small. The listener will unconsciously adjust the volume to a larger one.
In the other case, the opposite is true: the poorer headphones have very weak bass, and in order to hear the bass, the listener will deliberately put the volume down.
Note that human hearing is not sensitive to sound intensity (volume) in the low and high-frequency areas, which means that you need to have a louder volume to let you hear.
If the sound intensity output of the headphones in these bands is inherently attenuated, the listener must adjust the volume to a large extent to hear the sound of these bands.
Black Magic III: Just let you not understand
When you practice English listening, you can’t understand the conversation. It’s not because you didn’t understand it, but because your English is still very scum, but you actually listened to it but didn’t understand the sentence.
In addition, when the phone is poor, the sound quality is unclear, and it is forced to adjust the volume of the call to a large amount, and the damage to the hearing is also great.
Black Magic IV: Feelings Lost
When the volume of sound or other environmental noise is too loud, we will not only feel the ears uncomfortable, but also the body and skin will feel strong air vibration;
In addition, you can compare the actual volume of the volume. For example, if you hear the music of a big speaker of a merchant on the road, the music is louder than the car horn. It must be too noisy, so it is easier to detect the danger.
But if it is a headset, on the one hand, the skin does not feel at all, and on the other hand, there is no contrast, so it is difficult for us to have an accurate estimate of the volume of the headphones.
The above four black magic make a great deviation in the judgment of the real volume of the headphones, and may exceed the safety range by up to 20 decibels, which means that your hearing health is being seriously damaged!
Protective hearing program
1. Buy high-fidelity noise-canceling headphones, and good-quality in-ear earphones may be better.
2. Determine the most appropriate headphone volume on each playback device and leave it as it is.
3. Avoid using headphones to listen to music in noisy situations, but you can wear a noise-canceling headset.
A good pair of headphones not only enhances your music appreciation but also protects your hearing health. You need to know that the expensive audio equipment is not as good as a pair of good ears. Protecting your hearing is really more important than anything you love music!
Find the right volume
So, the premise is that you have done the first item above, and then in order to determine the optimal volume of your headset on device A (such as the Walkman), you also need another auxiliary device B with an external device, such as a mobile phone or computer. Speaker.
Proceed as follows:
1. Pick a quiet time, first use device B to play a more unrestrained song, adjust the volume so that it does not exceed the normal voice of the person;
2. The headset only wears one ear, inserts the cable into device A, plays the same music, and it is best to play the two devices synchronously;
3. Only adjust the volume of the A device to balance the volume of the left and right ears (one ear listens to the A device earphone and the other ear listens to the B device), which is the most suitable earphone volume on device A.
Of course, different devices and different headphones have different optimal volume levels and need to be debugged separately.
If you feel that the best headphone volume is not enough for you to listen to music, it means that your headphone quality or noise reduction performance is too bad, or the ambient noise is too large to stay for a long time, please leave as soon as possible, to a quiet place. go with.
To use in-ear earphones, you must choose a rubber sleeve that matches your ear size. Too big will cause discomfort or inflammation of the ear canal. Too small will not reduce the noise and affect the sound quality (mainly affecting the base texture). There is no uniform standard. tried.
In addition, if you are oily ear canal, you should replace the new rubber sleeve regularly. Some bad quality rubber sleeves are easy to swell and deform when they are immersed for a long time, and the dirt and dirt will be hard and cause infection.
