Generally speaking, people have their own ability to accept sound decibels. Some people are 50 decibels, and some people 100 decibels. This is also a decibel world that they are willing to accept at will.
The heart will resist the unbearable sound decibels, that is, after the subconscious gives an opposition signal, the human body will have feedback perception.
For example, listening to music, some music sounds good and some music sounds bad, which is why your melody consciousness will choose the sound you like to listen to with the rhythm.
A little physical discomfort, there will be some health risks, such as these hidden dangers from the heart.
Second, hearing the unacceptable sound shell is also the frequency of the heart beating, giving the information of consciousness resistance, and it is also the guidance within a person's health.
For example, the pitch is too high, some people's hearts can't stand it, some people have headaches, some people are nauseous, and everyone can't stand opposing audio sometimes.
This is because people have different physical conditions and have unbearable gravity for volume. This is also because the ear is unwilling to enlarge an audio frequency, and it will reject a decibel in the direction of its own ailment.
Over time, the health consciousness is formed, and suddenly it is different. If some frequency awareness is changed, this healthy range will be violated, forming a danger signal that the heart first perceives.
Third, if you can usually listen to the world with high decibels, you suddenly find that you can't hear the sense of direction with high decibels recently. It is also a healthy way to use external frequency to reflect some ailments of your body.
For example, standing and chatting, originally chatting well, suddenly felt uncomfortable and uncomfortable. This is also the fatigue consciousness given by my recent living habits. With decibels, I'm just surprised at some concerns that I didn't pay attention to when chatting.
Heart discomfort has the direction of self-induction, which can change the habits of the sound world. For example, the bass area is always comfortable and the treble area is always uncomfortable. You can choose the sound conditions you like.
In reality, whose voice scares you unhealthy, you should ask TA to speak softly, or don't suddenly raise your voice when communicating.
