What makes your voice change?

The type of your voice depends mainly on your vocal cords. The vocal cords are made up of elastic fibers. You can compare them to very good violin strings. The vocal cords may be tense or relaxed. What's more, your vocal cords can take on any of 170 different positions. When the air you exhale hits your vocal cords, they begin to vibrate. This vibration produces sound waves.

When the vocal cords are relaxed, they can vibrate at about 80 times per second and produce a low pitched sound as a result. If they are tense, they vibrate more frequently, perhaps up to 1000 times per second, and generate short sound waves, i.e. a high-pitched sound. The child has short vocal cords. Because they produce short air waves, the baby has a high, sonorous voice. As the child grows, the vocal cords become longer. Due to the fact that they become longer, the voice becomes lower.

The average length of male vocal cords is longer than that of females, so male voices are lower. In boys, growth is very fast, and the larynx also changes so quickly that they cannot get used to it and control its work. Therefore, very often we say that teenagers "break their voice." Although in general the pitch of the adult voice depends on the length of the vocal cords, each voice belongs to a specific timbre.

Voices can be divided into six groups: bass, baritone and tenor for men; alto, mezzo-soprano and soprano for women. The features of the human voice depend on many other things, especially such as the trachea, lungs, nasopharynx and the like. People with beautiful voices have resonant spaces that are shaped, and people know how to control their voice with them.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Fish in outer space 23.07.2023

China is preparing to send zebrafish to the Tiangong space station to study their interactions and effects on other organisms in a limited, closed ecosystem. The main focus of the study will be on the study of the possible loss of bone density in astronauts during prolonged stay in a microgravity environment.

The new study aims to study the loss of bone density that astronauts can experience during prolonged exposure to zero gravity. This issue could have a significant impact on future space missions.

This is not the first time fish have been sent into space. In 1973, a group of fundulus fish were sent into Earth orbit to the first Skylab science laboratory to study their response to weightless conditions.

The fish managed to successfully incubate dozens of eggs, from which newborn fish fundulus emerged, able to adapt to weightlessness.

Also, the Japanese space agency conducted a study of the effects of microgravity on a small group of medaka fish aboard the International Space Station.

The results of the study showed that the fish experienced a significant deterioration in well-being and, almost immediately after arriving at the ISS, began to lose bone density. Typically, such effects are observed in astronauts after about 20 days of stay in the space environment.
