Speech is a social activity and a form of publicity used in public places. In order to explain the audience, impress the audience and "conquer" the masses with thoughts, feelings, examples and theories, it must be realistic and targeted. Next, I will bring you a speech by the leaders of Love Ear Day. I hope you like it!

Love Day 1 Speech by Teachers and Students Leaders:

Good morning!

The topic of today's speech in our country is "reducing noise and protecting hearing".

March 3 is the fourth national ear-loving day. The theme of this national ear-loving day is "reducing noise and protecting hearing".

Long-term exposure to noisy environment will lead to permanent hearing loss.

Many people have habitually relied on headphones to listen to music, as if wearing headphones can lead themselves into another world without interference from others. "Many people think that only 80 decibels or more will lead to hearing loss. In fact, less than 80 decibels can also cause deafness.

Relevant medical data show that when the volume heard by human ears reaches 100 decibel, it will cause irreversible hearing damage for a long time; When the volume is as high as 1 10 dB, it is enough to kill the hair cells in the inner ear of human body, and even cause hearing loss in severe cases. "In fact, when many teenagers are listening to ktv or rock music, the volume has far exceeded 80 decibels." The volume of some mp3 players can be as high as115db. Even if the volume is not turned to the maximum, it can exceed 90db when listening to passionate music.

"Even if it is slightly lower than 80 decibels, it is still dangerous." The number of decibels that damage hearing is inversely proportional to time. "If noise above 100 decibels can permanently damage people's hearing in only three to five months, then it may take half a year for 80 decibels to have this consequence. In the environment of 60 or 70 decibels, it may bring irreversible deafness for a long time, but the time will be longer and it will be less noticeable. "

The hearing level of modern people is much lower than that of 50 years ago. Many young people have more or less slight hearing loss because they are in a noisy environment all day. "Stereo, TV, mobile phone, mp3, telephone ... are eroding people's hearing more or less."

Listening to headphones for half an hour should rest, wearing headphones to sleep will double the damage.

With the same decibel number, the harm of listening to music with headphones is far greater than that without headphones. This is because most headphones are in-ear design, and too loud volume will directly damage the eardrum. Therefore, many regions such as Europe do not advocate the use of earplugs.

"Compared with externally played music, headphones lack sound buffering and filtering functions, so even if the decibel number is slightly lower than externally played music, the lethality may not be bad at all." It is understood that there are two kinds of headphones on the market at present. Headphones have good listening effect and are easy to carry, but the damage to the ears of the two headphones is actually the same. Listening to music with headphones, because the eardrum is very close to the earphone diaphragm, the sound wave conduction range is small and concentrated, which greatly stimulates the auditory nerve of the eardrum.

In busy public places, such as streets, buses and subways, people will unconsciously increase the volume because of the interference of surrounding noise, which will do more harm to their ears, so it is best to listen to earphone music in a quiet environment. "Although the total volume of stereos, radios, mp3 players and mobile phones produced and designed by different manufacturers is different, most of them will be tested and limited to an acceptable range for human ears." The highest value in this range may still exceed 80 decibels. Therefore, it is suggested that if you wear headphones to listen to music such as mp3, the volume should not exceed 2/3 of its designed total volume.

In addition, don't listen to music with headphones for more than half an hour at a time, and then be sure to let your ears rest completely. At the same time, you must not listen for a long time, and it is best not to exceed 1 hour at a time. So don't wear headphones when you sleep, or you may fall asleep accidentally, and your ears may listen for more than a few hours continuously, which will obviously increase the damage. Students, let's stay away from noise and protect our hearing from now on.

Good morning, children!

Today, Teacher Zhang will give a speech under the national flag. Teacher Zhang invited everyone to listen to a few idioms first: cover one's ears and steal the bell, give advice when unpleasant to the ear, be familiar with it, and arouse the deaf. Have you ever heard of a word in these idioms of Teacher Zhang? What is this?

Yes, ears are one of our five senses. Do you know what the function of ears is? Come on, let's close our eyes and listen. Don't make any noise. Listen quietly. Can you hear teacher Zhang's voice? Can you hear your breathing? Do you hear these voices?

Our daily life, our classroom and our activities with children are inseparable from our ears. Ear plays a very important role in our life. Therefore, March 3 every year is China's Love Ear Day. This year is our _ _ th National Ear Love Day, with the theme of "reducing noise and protecting hearing". Tell teacher Zhang again: reduce noise and protect hearing.

Children may not know that medically speaking, our ears are divided into four parts: outer ear, middle ear, inner ear and auditory nervous system. Usually, all we see is the external ear. Protect our ears so that our hearing will not be affected. Do you know what to do? Listen to teacher Zhang tell you:

First, avoid going to places that are too noisy, such as karaoke bars and construction sites. Noise from these places is very harmful to our ears.

Second, when we listen to music with headphones, don't turn the volume up too much. Moreover, doctors recommend that you wear headphones to listen to music for no more than one and a half hours every day.

Third, don't think that pulling out your ears is clean. In fact, it is easy to scratch or scratch the inside of the ear, causing otitis media, otitis media and even more dangerous consequences. Therefore, we children must not pick our own ears.

Fourth, when we wash our hair or take a bath, we should prevent sewage from flowing into the ear canal. Try to wear earplugs to protect your ears when swimming.

Finally, when we are playing, don't pull other people's ears to play.

Can children remember the above points? Finally, Mr. Zhang wants to tell you that our listening will decline with age. Therefore, if there are elderly people in our family, turn up the TV when watching TV, or ask questions repeatedly when talking to us, we should not be angry. We should think about whether the hearing of the elderly has declined. We should be more patient and understanding, and be good children who care about their elders.

Finally, I hope everyone will take care of their ears and protect their hearing, starting from their daily lives and caring for their elders' hearing health from now on. Let's get started.

Dear teachers and students, Speech by the leaders of Love Day 3:

Good Morning, everyone! Today, the topic of our national speech is "Wonderful World-I heard it". The teacher tested everyone: Can you write "smart" and "smart"? Whose side is he on? Yes, it's next to the word "ear". This tells us that a smart person must have good hearing skills. Take our pupils as an example. We should listen attentively to the teacher's lecture, listen attentively to others' reading and talking, and enjoy the wonderful music and all the sounds of nature with our ears, grand, weak, sonorous and soft … ears are very important!

According to the information provided by relevant departments, there are currently 20.57 million deaf-mute disabled people in China. Among them, deaf children can reach more than 1 10,000. This has aroused great concern of the whole society. In 2008, China designated March 3rd as the national "Love Ear Day".

So how can we protect our ears? The following teacher will introduce you to several ear protection tips:

1. Avoid places that are too noisy, such as karaoke and discotheques.

2. In noisy environment, you can wear appropriate ear protectors and earplugs.

3. If you have ear inflammation or tinnitus, please see a doctor immediately.

4. Don't turn the volume too loud when listening to cd, md and mp3 with headphones.

5. Earwax is a kind of secretion that naturally protects the external auditory canal, commonly known as earwax. No special cleaning is required. Don't think that picking out your ears is clean and comfortable. In fact, it will only push most of the earwax deeper into the ear hole, forming an impaction and even causing more dangerous consequences.

6. When washing your hair or taking a bath, you can plug your ears with cotton balls to prevent sewage from flowing into the ear canal.

Students, we know so much, so we should learn to protect our ears and hearing scientifically from now on, because almost all these factors that lead to hearing loss can be prevented, but they have not been paid enough attention to, which has led to hearing loss.

Students, finally, I wish you all have a pair of healthy and smart ears, so that we can hear the wonderful world. Thank you!

Dear teachers and students, today is March 3, and it is also the National Ear Love Day. The theme of the publicity and education activities of the first national ear-loving day in 20 10 was to pay attention to children and hearing health.

Ear is one of the most important organs in our human body, but many of our daily habits are constantly damaging our ears, such as swimming in the water, listening to songs with headphones on for a long time, etc. These are very bad. If our ears are hurt and we can't hear the sound, we can't hear the teacher's lecture, which will affect our study and bring great inconvenience to all aspects of life. Today, we will talk about how to protect our ears every day.

1, pay attention to the time when wearing headphones, not too long.

Now there is a very common phenomenon, especially many teenagers, whether walking, waiting for the bus, taking the bus or eating, are holding mobile phones in their hands and wearing headphones in their ears. In fact, if you wear music headphones for a long time, your ears will always feel dull pain, because our classmates are young and can't feel it now, but what is certain is that there will always be problems with your ears in the long run. Therefore, students who like listening to music should try to pay attention to the combination of work and rest, rest for about an hour and let their ears breathe. In addition, firecrackers, some noisy toys, shouting in the ear and so on. Will cause damage to the ears. The louder the sound, the longer the contact time, and the greater the impact on our hearing.

2. Rub your ears as little as possible, and never rub your ears with sharp tools.

If we often use headphones to listen to songs or other things, our ears are more likely to produce more earwax, occasionally accompanied by itching, always want to pick our ears, and sometimes accidentally hurt our ears, making it easier to cut the ear canal and even damage the eardrum. In fact, earwax is a mixture of dead skin secreted by ear oil. Generally, it will be discharged by itself without cleaning, but pushing it back will constitute an ear canal blockage. At the same time, ear oil has a bactericidal effect, and earwax is like a small line of defense to prevent dirt from invading. So, don't dig your ears. If there is indeed a lot of earwax that blocks the ear canal and affects hearing, parents should take it to the hospital to find a doctor to help clean it up.

3, pay attention to the cleaning of the external ear every day, pay more attention to washing around the ear when washing your face every day.

Sometimes we may not notice that we often leave a lot of dirt on the outer ear and behind our ears, because they are invisible and no one pays attention to them. Therefore, it is recommended to clean the outer ear, especially behind our ears. Generally, when washing your face every day, it is enough to wash the back of your ears intentionally.

4. Take a bath and clean the water in the swimming ears in time.

Take a shower, wash your hair, or when we swim, we should pay attention to the waterproof of our ears. When you accidentally get water into your ears, especially unclean water, you must pay attention to cleaning it in time, otherwise it will easily become inflamed. If there is water in shampoo and shower gel, come out and suck it up with a cotton swab. If you swim with water, tilt your head to one side and jump on tiptoe, the water will come out.

5. blow your nose.

When you have a cold, don't hold both sides of your nose and blow your nose together, so as to avoid excessive pressure, and the nasal mucus with bacteria will enter the eustachian tube and reach the middle ear, causing otitis media. You should blow your nose one by one.

Watch your ears. Please remember a children's song: ears grow on both sides of the head, and you need to listen to the sound for help. Do not dig, protect yourself, and have a strong ability to listen to all directions. Thank you!

Speech by the leaders of Love Ear Day 5 March 3 every year is the national "Love Ear Day". As early as1March 1998, at the first meeting of the _ _ session of the National Committee of the China People's Political Consultative Conference, 15 member put forward the proposal of "Advocacy on Suggesting the Establishment of Love Ear Day" in view of the current situation of high incidence, large quantity, great harm and weak prevention of deafness in China. At that time, this proposal attracted the attention of relevant departments, and China Disabled Persons' Federation, Ministry of Health and other departments 10 agreed to designate March 3rd as National Ear Love Day from 2000.

According to the information provided by relevant departments, there are currently 20.57 million deaf-mute disabled people in China. Among them, deaf children can reach more than 1 10,000. Therefore, protecting teenagers' hearing health has attracted great attention of the whole society.

Students, we understand these truths. From now on, we should learn to protect our ears scientifically and protect our hearing. Because almost all these factors leading to hearing loss can be prevented, but due to insufficient attention, more and more people lead to hearing loss.

How to protect your ears? The teacher introduced several ear protection tips:

1. Avoid places that are too noisy, such as karaoke and discotheques.

2. Wear appropriate earmuffs and earplugs in noisy environment.

3. If you have ear inflammation or tinnitus, please see a doctor immediately.

4. Don't turn the volume too loud when listening to cd, md and mp3 with headphones.

5. Earwax is a kind of secretion that naturally protects the external auditory canal, commonly known as earwax. No special cleaning is required. Don't think that picking out your ears is clean and comfortable. In fact, it will only push most of the earwax deeper into the ear hole, forming an impaction and even causing more dangerous consequences.

6. When washing your hair or taking a bath, you can plug your ears with cotton balls to prevent sewage from flowing into the ear canal.

Finally, I wish everyone a pair of healthy and smart ears. Thank you!
