1. bitcoin mining machine is also a computer. How much noise does the computer make when it is turned on is equal to its noise
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server.

2. Avalon mining machine consumes a lot of electricity. It's difficult to earn back the electricity bill and it's noisy. Guangtian mining machine reminds you to understand these before you buy it. Ants are more cost-effective, quiet and low consumption. If they are bigger, they choose the 1t miner of Ajie of longkuang.
3. According to; After a lot of investigation and understanding,
decibel is the sound pressure level unit, recorded as dB, which is used to represent the sound measurement unit (sound size)
the sound just heard by the human ear is 0-10 dB. When the decibel value increases by 10, the volume increases by 10 times,
& 65279; That is, from 1 dB to 20 dB means that the volume has increased 100 times
0-20 dB, very quiet, almost imperceptible< br /> 20-40 decibels, equivalent to speak softly
40-60 dB, equivalent to ordinary indoor conversation
60-70 dB, which is equivalent to shouting and damaging nerve
70-90 dB, very noisy, noisy street noise
learning and living in this environment for a long time will graally destroy human nerve cells
90-100 dB, noisy bar sound, air pressure and electric drill sound will cause hearing loss
100-120 decibels, which makes people intolerable. People feel pain in their ears, and can be temporarily deafened in a few minutes
decibel value can also be divided into the following areas< br /> Below 60 is the harmless zone,
60-100 is the transition zone, and
100 is the harmful zone
when the sound is about 30 decibels, it will not affect the normal life and rest.
when it is above 50 decibels, people have a greater feeling and it is difficult to fall asleep&# 65279;
car noise is 80-100 decibels, and TV sound can reach 80 decibels.
if people live in 85-90 decibels noise environment for a long time, they will get "noise disease"< br /> The sound of a chainsaw is about 110 decibels, and that of a jet plane is about 130 decibels< br /> When the sound reaches more than 100 decibels, people will feel pain in their ears, which can cause temporary deafness in a few minutes
the so-called noise refers to people's unwanted and boring voice&# 65279;
it can directly affect people's nervous system, make people irritable and irritable, affect sleep and cause fatigue
in order to prevent noise, Professor Ma Dayou, a famous Chinese acoustician, summarized and studied the hazards and standards of various kinds of noise at home and abroad, and put forward three suggestions: (1) in order to protect people's hearing and health, the allowable value of noise is 75 ~ 90 dB 2) The allowable value of environmental noise is 45 ~ 60 dB 3) For sleep time, 35 ~ 50 dB is recommended<
it has effects on human immune function, spirit, nerve, cardiovascular system, endocrine system, metabolism, respiratory system and digestive system; Cause tension, worry and disgust< br /> &# 65279; If you are disturbed by low-frequency noise for a long time, it is easy to cause neurasthenia, insomnia, headache and other neurosis.
the ideal sound intensity environment for women ring pregnancy is no less than 10 dB and no more than 60 dB< br /> When pregnant women are exposed to 60-80 decibels of noise for 2-4 hours a day, they will feel depressed and nervous,
their breathing and heart rate will increase, and their cardiopulmonary burden will increase; Neurological dysfunction,
, 65279; Headache and insomnia follow; It may even affect the fetus in the womb,
therefore, women should try to avoid the influence of noise ring pregnancy.

4. According to the OSHA regulations, the human ear can withstand 85 dB sound intensity for 8 hours without negative effects. These laws and regulations affect the design of instrial earphones. However, in consumer procts, there is no rigid regulation on the maximum sound intensity
what is the maximum volume of most MP3 players circulating in the Chinese market? Generally, the maximum volume of MP3 is about 110 dB
sound below 40 dB has no effect on human body; When the sound is between 40 dB and 60 dB, if the human body is in this environment for a long time, the nervous system will be affected. At this time, the noise energy will be doubled when the noise is increased by 3 dB on average; When the sound reaches 65 dB to 80 dB, the degree of cardiovascular injury is more than 20% higher than that of people living in the environment of 50 dB noise. When the noise exceeds 80 dB, it will cause great damage to people's hearing. When the noise exceeds 100 dB, it is intolerable. The sound is more than 120 decibels, which is equivalent to a Boeing 747 flying by. Human health will be greatly damaged in a short time.
