hallástartomány

Hallástartomány refers to the range of sound frequencies that a particular organism, most commonly humans, can perceive. This range is typically measured in Hertz (Hz), which represents cycles per second. The human hallástartomány generally spans from approximately 20 Hz to 20,000 Hz. Frequencies below 20 Hz are considered infrasound, and those above 20,000 Hz are termed ultrasound.

The sensitivity of an organism's hallástartomány can vary significantly. For humans, the ability to hear higher frequencies tends to diminish with age, a phenomenon known as presbycusis. Factors such as prolonged exposure to loud noises, certain medical conditions, and genetic predispositions can also affect the extent and quality of an individual's hallástartomány.

Different animal species possess hallástartomány that differ from humans. For instance, dogs can hear frequencies up to 45,000 Hz, while cats can perceive sounds as high as 64,000 Hz. Bats and dolphins utilize much higher frequencies for echolocation, extending their auditory capabilities well into the ultrasonic range. Conversely, some animals, like elephants, can detect infrasound frequencies, which are important for long-distance communication. Understanding an organism's hallástartomány is crucial in fields such as audiology, acoustics, bioacoustics, and animal behavior studies.
