There is one type of noise source in life that will be overlooked, and that is the noise generated by household appliances. The data shows that at a distance of 1 meter, the sound level of televisions, radios, and tape recorders with amplified volume can reach 60 70 decibels; electric fans are 42 70 decibels; refrigerator is 34 50 decibels; The motor sound when the washing machine is turned is 60 70 decibels; hair dryer is 55 90 decibels; 47 60 dB for electric shavers; The sound level of the speaker is up to 90 decibels. It can be seen that the noise of household appliances is no lower than the noise of car horns on the road.
To reduce or avoid noise hazards in the home, first of all, try not to put noisy appliances in the same room. For example, the washing machine should be placed in the patio or bathroom as much as possible. Do not put the refrigerator in the bedroom, the walls should not be too smooth, and hang some mirror frames on the wall, which can not only beautify the room, but also reduce the echo in the room.
In addition, it is best to put a few pots of flowers indoors, which can not only adjust the microclimate, but also reduce noise.
Don't turn up the volume too high when watching TV or listening to the radio, only the right volume can feel the melodious and pleasant sound. If you are in an environment above 100 decibels for several hours, it will cause irreversible damage to your hearing.

The effects of noise on hearing are varied, and when the intensity of noise is low, it generally does not cause temporary or permanent damage to the auditory system. When the intensity of the noise is high, it can lead to temporary hearing loss. This loss lasts for a while when the noise is aborted.
If the noise intensity is too high, it can cause damage to the internal structure of the cochlea and permanent hearing loss.

Household appliances generally emit some background noise when working, and the noise level is not very loud in the steady state, so it will not affect hearing. If you are exposed to a loud environment for a long time, it will affect your hearing. Hope.

Depending on the situation, watching TV for a long time may cause hearing loss.

Hello, excessive noise of electrical appliances will affect hearing health, so when using household appliances, you must use them scientifically and reasonably, such as the volume of the TV should not be too large, and some noisy electrical appliances should not be used at the same time, otherwise the noise will increase. All kinds of electrical appliances should not be placed too close to each other, the closer the distance, the louder the noise, all kinds of household appliances should be 1 meter away from our rest and work. In addition, the accessories on some electrical appliances should be tightened well, and various loose screws should be tightened in time, otherwise unnecessary noise will also be generated.
In addition, some old household appliances due to the aging of internal parts, as well as the influence of dust, will also have a lot of noise, such household appliances not only consume electricity, but also have some potential safety hazards, there will be various noise problems, etc., therefore, after the service life of the imitation and the first household appliances should be replaced in time.
Another very important point is that many people will wear headphones when using computers and mobile phones, and the sound should not be too high, not more than 60 decibels;The time should not be too long, no more than 30 minutes at a time. If a person who regularly uses headphones has itchy ears, tinnitus, and has to raise his voice to speak, this is a sign of hearing loss and should seek medical attention as soon as possible to avoid serious consequences.

Under normal circumstances, 70 decibels will start to damage the hearing nerves, 90 decibels will cause hearing loss, and 100---120 decibels will cause temporary deafness in a person.

The United Nations Organization for Economic Co-operation and Development's study of noise pollution has concluded that the average limit of noise that people can tolerate should not exceed 65 decibels
For example, an electric fan is 45 to 50 dB;The washing machine is 60 to 80 dB;The refrigerator is 30 to 40 dB;The TV is 50-70 minutes cherry blossoms;The cassette recorder is 80 decibels;The hair dryer is 50-60 decibels;The electric shaver is 47-60 minutes of filial piety ......Thus.

The United Nations Organization for Economic Co-operation and Development (OECD) study on noise pollution has concluded that the average limit of noise tolerance should not exceed 65 decibels. The sound level of the household appliances we usually use at home is relatively high.
For example, an electric fan is 45 to 50 dB;The washing machine is 60 to 80 dB;The refrigerator is 30 to 40 dB;The TV is 50 to 70 dB;The cassette recorder is 80 decibels;The hair dryer is 50-60 decibels;The electric shaving shaver is a blind 47 60 dB ......It can be seen that Zhijiankong only starts two household appliances at the same time, which greatly exceeds the sound level standard of urban interiors.

This is a problem with the duck shed line, because the power of the duck shed lamp will not be large enough to reduce the voltage to affect other household appliances, so the analysis should be a short circuit fault in the duck shed line, resulting in a large current in the loop, and the voltage is reduced a lot, which affects the use of household appliances, of course, this short circuit is not a very direct short circuit, such as inductive short circuit to form a loop of large current, voltage reduction, or is connected to the earth but not well connected, etc., will form a large current, High voltage drop affects the use of other household appliances.
