Recognize noise with a discerning eye and draw it!

What is noise? Whatever you think it is.

Noise is whatever you draw.

Any sound that makes us feel physically or psychologically uncomfortable, any sound that is unwanted, annoying, or affects conversation or thinking is considered noise.

In other words, not only the sound of burning machines and honking of vehicles, but also the noisy and sudden sounds of people and other sounds that affect people's study, work and rest are considered noise. As long as you don't want it to be, music can also be noise.

Because noise is somewhat of a subjective assessment based on one's own situation.

Noise can be drawn in size.

The relative subjectivity of noise does not mean that we cannot discern the “sound” with wisdom. We can grasp its characteristics and clearly draw the noise.

Usually people tend to feel that there is a reference range after a certain decibel level, which is considered noise.

Normally speaking, if you want to have a good rest, the noise level should not exceed 50 decibels, and if you want to stay mentally focused, the noise level should not exceed 70 decibels.

And if the noise level increases further to 90 decibels, even if you want to curse or hit someone, the doctor will understand - because living in a noise environment above 90 decibels for a long time can cause mental weakness and other physiological diseases.

Noise can be used to draw colors.

Although we cannot see noise with our naked eyes, its family is colorful.

White noise is a "magician" that is composed of all colors but looks like white light. Its frequency and power in a sound are uniform throughout the audible range. It sounds like the sound of rain or waves hitting rocks. It is so beautiful that it is widely used in environmental acoustic measurements.

Pink noise is as sweet and gentle as its name suggests. The human ear perceives it as "very pleasant". Pink noise is the most common noise in nature, produced when raindrops hit the sidewalk, breezes rustle through the branches of trees, and waterfalls fall into valleys. It is most often used in acoustic testing.

In addition, there is the mysterious big brother black noise that people cannot perceive and the naughty little brother brown noise that is similar to the rumble of a factory.

Noise, it attacks multiple organs.

When we are in an environment that exceeds the hearing protection standard for a long time, that is, greater than 80 to 90 decibels, our hearing fatigue will be difficult to recover, and continued accumulation will cause irreversible physiological changes.

Noise not only affects the auditory organs, but also "affects" the visual organs through the nervous system, causing people's vision to weaken or cause eye pain, dizziness, etc. Studies have shown that noise can cause abnormalities in color vision and color field of view.

In addition, long-term exposure to noise can cause high blood pressure, lead to heart disease, and cause the cerebral cortex to lose balance in the process of excitement and inhibition, leading to symptoms such as palpitations, insomnia, general weakness, headache, nausea, and neurasthenia.

Can’t escape? Protect your ears with a balanced diet.

The most annoying thing about noise is that even though we know so many reasons, we often have to endure it and it is difficult to simply avoid or escape it because noisy environments are everywhere in modern life.

So can we eat it?

The answer is yes. Eat more and know how to eat, and your ears will be better.

For example, foods rich in vitamin A, such as animal liver and fish, can enhance the activity of ear cells.

Eating more iron-rich foods can reduce anemia symptoms, fatigue, and slow down hearing loss. Common dishes such as eggs and broccoli are good choices.

At the same time, we must also ensure the supplementation of vitamin D and calcium foods, which can protect the bones in the ear tympanic cavity, prevent osteoclerosis, purify the ear artery, and improve ear function. Common ones include seafood, beans, etc.

In short, we must learn to identify and "see" real noise so that we can reasonably avoid and protect multiple organs in the body.

On the other hand, through a proper diet and a good attitude, you can also remain energetic and vibrant even in a sound environment with a certain impact.
