This video is an educational experiment about the speed of sound, conducted by a team inspired by MegaFon, the number 1 mobile operator in Russia. The team aims to demonstrate the effect of sound waves scattering and how they can be focused to transmit voice over a distance.
The experiment begins with a discussion about the characteristics of sound waves, including their ability to scatter. The team then constructs a large pipe to serve as a makeshift transmitter and receiver, focusing the scattered sound waves. They use this setup to communicate over a distance of 15 meters in the office, showing that the sound can be heard clearly.
The team then increases the scale of the experiment, using a pipe 30 meters long to communicate over a distance of 30 meters. They also test the pipe in a noisy environment on the street, showing that the sound can be heard clearly despite the background noise.
The team then aims to break the world record for the longest distance sound can be transmitted. They take the pipe to a field 150 meters away and manage to communicate over this distance. They then attempt to increase the length of the pipe to 330 meters, the speed of sound, to demonstrate the principle that sound travels at approximately 330 meters per second.
Despite the success of the experiment, the team experiences a drop in the quality of the sound as the distance increases. They also attempt to eavesdrop on the conversation using a stethoscope, demonstrating the principle that sound waves can be focused.
The experiment concludes with the team successfully transmitting voice over a distance of 330 meters, breaking a world record and demonstrating the effect of sound waves scattering and focusing. The team encourages viewers to use MegaFon for their mobile needs, highlighting the importance of speed and coverage in communication.
1. The video is about the speed of sound and aims to break the world record for the longest distance over which sound can be transmitted. The experiment involves using a pipe to transmit voice over a distance. [Source: Document 1]
2. The experimenters aim to achieve such an effect that when saying something, the sound reaches the other end of the pipe in a second. [Source: Document 1]
3. The previous record for the longest distance over which sound can be transmitted was 180 meters, set in India. However, the experimenters aim to achieve an effect where the sound reaches the other end of the pipe in a second. [Source: Document 1]
