Now more and more students like to listen to music or something, but wearing headphones to listen to MP3 will damage their hearing. In recent years, MP3 has reached an unprecedented popularity. People listen to music with headphones and call for more and more time.

However, long-term use of headphones will bring great damage to their hearing. If it is not suitable to listen to people aged 40 to 40 in the future, it will cause deafness When members listen to music, we need to wear hearing aids and earphones to listen to music. There is no air filter for the sound.

There are some noises. Under the same decibel condition, the sound is bigger than that from the outside. There are some solutions.

First, the volume should not exceed 11% of the total volume recommended by the earphones. Second, I listen to music for no more than 30 minutes at a time, and I have regular hearing tests Only in this way can we use headphones that are useful.

_Earphone_ is a kind of entertainment tool commonly used by modern people, but with the development of science and the progress of human beings, people often forget the harm of these high-tech products to human beings. Headphones are the killers of our health. Whether listening to the radio or listening to music, the highest sound of earphones can reach decibels, which is several times higher than the ordinary noise.

When we are exposed to noise, we will produce Now tinnitus, hearing loss, if the exposure to noise for a long time, high-resolution sound wave in the cochlear concussion fluid, hair will be excessively stimulated, hearing loss is more obvious in daily life, the level decibel will interfere with conversation, distract people, not concentrate, affect work efficiency, even accidents, long-term work or living in decibel noise environment, will seriously affect hearing and guidance As a result, many other diseases are caused by the side effects of MP3 players. The sound near their earphones can even be heard. The noise is often higher than decibels.

Use MP earmuffs to accept noise decibels. The highest one has reached decibels. Therefore, we should pay attention to the er brought by earphones and use them reasonably.

Bluetooth is a general radio intece in the GHz band. It enables portable electronic devices to connect and communicate wirelessly through short-range ad hoc networks. Each piconet unit can communicate with multiple other units at the same time.

More each unit can belong to multiple piconets at the same time. Besides Ericsson, Bluetooth technology has also obtained Nokia IBM and many other systems Manufacturer support, so there is no need to provide cables and connectors for cordless phones or mobile phones using wireless headphones, computer printers, projectors or LANs, and pave the way for new and completely different products. Equipment and application technical features 1ms / s symbol rate uses maximum available channel bandwidth to quickly frequency hopping to avoid interference adaptive output power minimization interference short packets in Maximum capacity fast acknowledgement during interference allows low coding overhead cvsdcontinuous variable slope Delta modulation speech coding can run at high bit error rate.

Flexible packet types support a wide range of air intece applications. According to the small high-performance integrated radio transceiver, each transceiver is assigned a unique bit address from the IEEE standard, so as to minimize the current consumption of unlimited GHz available in the world Ism is running in free bandwidth, although the location and bandwidth are slightly changed, the application range is set to m to optimize the target market for mobile and commercial users. The total data rate is 1mbit / s, and the second generation plan is to increase it to 1mbit / s.

single point connection allows the maximum data transmission rate of kbit / s. The voice channel uses the packet switching protocol based on frequency hopping scheme with hop / sec to operate in noisy radio High performance in the environment. However, the maximum power consumption of 1 MHz ISI / S is available at a very low power consumption of 1 MHz / s in the standard IEEE MHz / s bandwidth when the data transmission is at a very low rate of 1 MHz.

Now most children like watching TV instead of reading books. In order to prevent children from being affected, parents only allow their children to watch cartoons in their spare time. Children must learn various skills, and they have no time to watch TV.

In my opinion, it is necessary for people to watch TV, especially for children. Watching TV is one of our fast-paced world A good way to relax, many people are under the pressure of work, some interesting programs always make people laugh, make people tired. Watching TV is a good way to understand current events.

For example, news programs on TV can focus your attention on knowledge. It provides you with information. When you talk to others, watching TV is a good way to experience life.

In every program, there is a program called _the art of life_ hosted by Zhu Jun. he invited some succesul people to share their experiences with the audience, Their spirit encourages people to overcome many difficulties in daily life. TV programs contain a lot of content, such as law, retelling, cooking, etc., just like a book, but it is more suitable for children than a book.

On the contrary, children are easy to remember what they saw and open their hearts to think. Parents also forget their feelings when they were children and trust their children. They can live with TV As a modern way of entertainment, you can live closer to the world.

Watching TV is the fashion in our daily life. I think watching TV is both good and bad for us. Watching TV is good for us, but watching too much TV will cause some problems.

As we all know, watching TV can help us relax and broaden our horizons. Students will learn a lot of knowledge and new information, which they can't learn in school. However, watching TV for unlimited time will cause some problems.

For example, in some cases, agers who lack self-control may indulge in TV and put their learning tasks aside. Watching TV has more advantages than disadvantages We should strike a balance between study and entertainment according to our specific situation.
