Information conference on the topic: "Living in the world of sounds is happiness."

The lesson plan was sent to: Artyukhova Lyudmila Ivanovna, teacher of physics, secondary school No. 56, Petrov Val, Kamyshinsky municipal district, Volgograd region [email protected]

Goals: consolidation of students' knowledge on the topic "Sound phenomena"; instill self-education skills, develop the ability to speak publicly; develop creative technical skills.

Equipment: oscilloscope, microphone, tuning forks, thread beads, musical instruments, metal ruler, beaker, tables, wall newspapers, home-made devices (flute,

erchok, bottlephone), balloons, sand, bell, student presentations, computer, multimedia projector.

Students are divided into groups: biologists, historians and writers, music lovers, architects, ecologists and doctors.

Organizing time

The performance of a small piece of music on the violin, the recording of a trill of a bird, the noise of a running engine.

Teacher:

What did we hear? That's right, sounds made by bodies.

I accidentally got a card. It has these lines:

I turn to you for help.

I am a deaf person.

Living in the world of sounds is happiness.

I don't have that happiness.

Natural sounds - I do not know.

There is no way to speak...

We have the opportunity to hear and speak.

People have long guessed that sounds can be born, move or die. Not having much knowledge, they made wonderful instruments, built beautiful theaters and cathedrals. But to

When the task arose to build a supersonic aircraft or create a high-quality recording, there is nowhere without science.

What is the science of sound called? That's right, acoustics. But there are physiological, architectural, technical acoustics. How do they differ? What do they have in common?

Today you are not just students, you are specialists who study sound in integration with other academic subjects.

The tablets on your tables indicate that you have seriously prepared for the information conference. What is the purpose of the lesson?

(Write on the board the topic and purpose of the lesson.)

Knowledge update

You need to open the conference using the key:

1. Vibrations of an elastic medium perceived by the human ear ( 1 letter).

2. The sound of one specific frequency ( 3 letter).

3. The branch of physics that studies sound waves ( 1 letter).

4. Low frequency vibrations that are not perceived by the human ear ( 1 letter).

5. Changes that take place in nature 1 letter).

I. The word is given to a group of biologists.

Messages (presentation):

1. Sources of sound in humans.

2. The structure of the hearing aid in humans.

4. Bioacoustics of fish.

Findings:

II. Historians and writers report on the fulfillment of the task.

Messages:

1. Talking statues.

2. Bluebells in the desert.

3. What is an echo?

4. Why does the wind howl?

Findings:

A piece of music plays.

III. Performance of section of fans of music.

1 student: Dear friends! Who among us doesn't love music? Opera, symphony, pop music is an integral part of the spiritual culture of mankind. Music can express feelings

and the thoughts of people of different nationalities, its language is understandable to everyone.

2 student: Music is great! But what about physics?

1 student: Music is sounds. The sound received by the tuning fork is the sound of one frequency. It's called musical tone. In the auditory sensation, sounds differ in pitch, loudness, timbre.

These physiological characteristics depend on the frequency, amplitude and shape of the oscillations. Look, here's an oscilloscope and a microphone. We excite the tuning fork. We see that the oscillations of the sine

distant, one frequency and amplitude. Let's hit harder. What was the amplitude of the oscillations? What is the sound volume? Let's try to pronounce the same word. Are the waveforms the same?

Conclusion:

1 student: We hear sounds from 16 to 20000 Hz. A sound with a frequency of 16 Hz is the lowest that a person hears. These sounds are produced by the organ. With the help of the piano, you can get sounds from 27 to 4096 Hz, violo

nchel from 65 to 1500 Hz, drum from 50 to 5000 Hz. Human voices are divided by frequency range as follows:

men's - bass, baritone, tenor; female - contralto, mezzo - soprano, coloratura soprano. The sounds of the lowest bass have a frequency of 60-350 Hz. Singer Kasper Fesper made sounds of frequency

2 student: Hear what a seashell sounds like. Why? How to eavesdrop on what is being said in the next room? Why is there a box for a phonendoscope? Why do we involuntarily open our mouths when

listening to a distant noise? What do all these tasks have in common? We observe the phenomenon of acoustic resonance. What it is?

Here are 2 tuning forks of the same frequency. Let's excite one of them, and then touch it with our hand. He fell silent. Let's repeat the experiment. Why do we hear the sound of another tuning fork? Vibrations of the first tuning fork

Vali air pressure difference, which led to the oscillatory movement of the branch of the second tuning fork. Having understood what resonance is, one can explain why the cameron, guitar, balalaika, violin

zhny resonator boxes. They contain air, which is an oscillatory system. The dimensions of the boxes are selected in such a way that the air column resonates on the fluctuations of the branches.

her tuning fork, strings. This will amplify the sounds. The phenomenon of resonance is used in all musical instruments. Organ pipes, wind instrument pipes, violin bodies, g

Itar, having a whole set of natural frequencies, resonate with the tones and overtones of primary sound sources, amplify their radiation, giving the sounds strength and timbre.

3 student: Here is the guitar. It only has 6 strings. But how many sounds can you get? Why?

(Demonstration of home-made musical instruments and an explanation of the principles of their work.)

IV. The word is given to representatives of architecture:

Our group needs to find out what properties of sound waves are used and taken into account in the construction of temples, concert halls and living quarters.

1 student: The duties of an architect include not only creating the external appearance of the building, but also thinking through the internal layout. Architects of past centuries planned halls for dining

meetings by trial and error. The ancient Greeks and Romans invented the amphitheater. Already in those days, they knew acoustic secrets that amaze us even now: on stage, you can break

cut a piece of paper and this faint sound will be clearly audible at the very top of the amphitheater, tens of meters from the stage. Wonderful acoustic effects were created in ancient temples: you can

then speak in one corner of the temple, and in the opposite whisper is perfectly distinguishable. In the construction of open amphitheaters and closed temple structures, reflection was used, pr

refraction and focusing of sound waves. There have been failures. It was worth at least a little change in the size of a well-planned building, and the new hall eliminated bad acoustics. Became needed theo

rhetic research. Architectural acoustics emerge. Its ancestor was the American physicist Valek Sabin.

Sound may be reflected in an enclosed space. This leads to reverberation - an increase in the duration of sounds. In this case, the speech will be illegible. Reverberation time depends on the material

fishing for covering the ceiling, walls, armchairs, from the shape and size of the hall. The absorption coefficient of all materials depends on the sound frequency. Wood, plaster absorb 3% of the incident energy from

wook. Fabrics absorb sound more strongly. The clothes of one person absorb as much sound energy as 20 square meters of plaster. The velvet-lined boxes are a thing of the past. Se

light, fire-resistant, porous materials are now used.

Experience: speak words into the microphone. Place cotton wool in the way. It can be seen that the oscillation amplitude has become smaller. We also use sound absorption by porous bodies at home. To make it quieter, put

upholstered furniture, carpets, upholstery is made of soundproof material.

The messages are accompanied by a presentation.

V. Report of the work of a group of ecologists and physicians.

We needed to find out how noise affects the physiological and psychological state of a person.

What is noise? What effect does it have on the human body?

Research work was carried out in the following areas.

1 student: What are the characteristics of sound: intensity and loudness, hearing threshold, pain threshold, noise characteristics of buildings, roads, a number of enterprises, sanitary standards;

2 student: A conversation with a safety engineer of a locomotive depot on the following questions: what is the noise level in workshops, in an electric locomotive, in a diesel locomotive? How do infrasonic vibrations affect a locomotive crew? Are there anti-sleep settings?

3 student: Conversation with a shop doctor: How often do drivers and assistants seek medical help? What is their age? How does noise affect the nervous system and hearing loss of crews?

4 student: With the help of a noise meter, the noise level was measured during recess at school, on the street, near schools, kindergartens.

5 student: Message about the dangers of misuse of portable players.
