The sounds having a frequency of 20 Hertz to 20,000 Hertz are known as...
An audio frequency is characterized as a periodic vibration whose frequency is audible to the average human. It is the property of sound that most determines pitch and is measured in hertz (Hz).The generally accepted standard range of audible frequencies is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors.

Understanding Audible Sounds
Sounds are classified based on their frequencies, which are measured in Hertz (Hz). The human ear can perceive a specific range of frequencies, which is crucial for communication and interaction with the environment.
Frequency Range of Audible Sounds
- Audible Sounds: The range of sound frequencies that humans can hear is approximately 20 Hz to 20,000 Hz (20 kHz).
- This range is commonly referred to as audible sound.
Other Sound Classifications
- Ultrasonics: Frequencies above 20 kHz (20,000 Hz) are known as ultrasonics. These sounds are inaudible to humans but can be detected by certain animals and used in various technologies (e.g., ultrasound imaging).
- Infrasonics: Frequencies below 20 Hz are classified as infrasonics. These sounds are also inaudible to humans and can occur naturally (e.g., earthquakes) or be generated artificially.
- Megasonics: This term is less commonly used and generally refers to very high-frequency sounds, typically above ultrasonics, often used in specialized applications.
Conclusion
In summary, sounds within the frequency range of 20 Hz to 20,000 Hz are termed audible sounds, making option 'A' the correct answer. This classification helps in understanding how humans interact with sound and its applications in technology, medicine, and environmental studies.
