Geluidsfrequenties

Geluidsfrequenties refer to the rate at which sound waves vibrate. This vibration is measured in Hertz (Hz), which represents cycles per second. The human ear can typically perceive frequencies ranging from approximately 20 Hz to 20,000 Hz. Lower frequencies are perceived as deeper sounds, while higher frequencies are perceived as higher-pitched sounds.

The audible spectrum, the range of frequencies humans can hear, varies from person to person and can change with age. As people get older, the ability to hear higher frequencies often diminishes. Different species have different audible ranges; for example, dogs can hear frequencies higher than most humans, while elephants can perceive very low infrasound frequencies.

Frequencies outside the human audible range are known as infrasound (below 20 Hz) and ultrasound (above 20,000 Hz). Infrasound can be generated by natural events like earthquakes or volcanic eruptions and can sometimes be felt as vibrations. Ultrasound is used in various applications, including medical imaging (sonography) and sonar for navigation and detection.

The perception of sound is a complex process involving the ear's structure and the brain's interpretation. The physical characteristics of sound waves, including frequency and amplitude (which relates to loudness), determine the sound we experience.
