Brilio.net - Sound is a very familiar phenomenon in everyday life. Starting from the sound of birds chirping in the morning to the roar of vehicle engines on the highway, sound is always around. However, did you know that sound has various types based on its frequency? The frequency of sound determines how the sound sounds and how the sound can be used in various applications.
The frequency of sound is measured in Hertz (Hz), which indicates the number of vibrations per second. Based on its frequency, sound can be divided into three main categories: infrasonic, audiosonic, and ultrasonic. Each of these categories has unique properties and different applications in everyday life.
This article will discuss in depth the types of sounds based on their frequency, properties, and applications. By understanding this, you can better appreciate the magic of sound and how it affects everyday life, Brilio.net reported from various sources on Tuesday (24/9).
1. Infrasound.Frequency: < 20 Hz
Properties: - Cannot be heard by human ears. - Can propagate through solid, liquid, and gas media. - Has a very long wavelength.
Implementation:
- Earthquake monitoring: Infrasound is used in seismology to detect and monitor seismic activity. Infrasound waves generated by earthquakes can travel through the Earth's crust and provide important information about the location and strength of the earthquake. - Animal communication: Some animals, such as elephants and whales, use infrasound to communicate over long distances. Infrasound waves can travel long distances through air and water, allowing these animals to communicate with members of their group who are far away.
2. Audiosonic.Frequency: 20 Hz - 20,000 Hz
Properties:
- Can be heard by the human ear.
- Low frequencies (bass) have longer wavelengths and can travel further.
- High frequencies (treble) have shorter wavelengths and are more easily absorbed by the media.
Implementation:
- Music and entertainment: Audiosonics are the frequencies used in music and various forms of audio entertainment. Musical instruments, sound systems, and other audio devices are designed to produce and reproduce sounds in this frequency range.
- Communication: Audiosonic frequencies are used in everyday communication, such as speech, telephone calls, and radio broadcasts. Microphones and speakers are designed to capture and transmit sounds in this frequency range.
- Acoustic testing: In the field of acoustic engineering, audiosonic frequencies are used to test and analyze sound quality in various environments, such as concert halls, recording studios, and theaters.
3. Ultrasonic.Frequency: > 20,000 Hz
Properties:
- Cannot be heard by the human ear.
- Has a very short wavelength.
- Can be reflected and focused with high precision.
Implementation:
- Medical: Ultrasound is used in the medical field for diagnostic imaging, such as ultrasonography. Ultrasonic waves are emitted into the body and the reflections are used to produce images of internal organs and tissues.
- Industry: In industry, ultrasonics are used for cleaning, welding and cutting materials. Ultrasonic waves can produce very strong vibrations, allowing for high-precision cleaning and processing of materials.
- Navigation and detection: Ultrasonic is used in sonar technology for underwater navigation and detection. Submarines and ships use sonar to detect objects beneath the surface of the water and measure the depth of the ocean.
Sound is a very complex and fascinating phenomenon. By understanding the different types of sounds based on their frequencies, we can better appreciate how they affect our daily lives. Infrasound, audiosound, and ultrasound each have unique properties and different applications, ranging from earthquake monitoring to medical imaging.
Knowledge of sound frequencies is also important in various fields, such as music, communication, and technology. By understanding how sound works, we can be more effective in using and developing technologies that utilize sound for various purposes.
Hopefully this article has given you some useful insight into the world of sound and how it affects our daily lives. Keep learning and exploring the wonders of sound!
