äänitaajuuksiin
äänitaajuuksiin refers to sound frequencies. Sound is a vibration that travels through a medium, such as air, water, or solids, as a wave. The frequency of this wave determines the pitch of the sound we perceive. Frequency is measured in Hertz (Hz), which represents cycles per second. Humans can typically hear sounds in the range of 20 Hz to 20,000 Hz, often referred to as the audible range. Sounds with frequencies below 20 Hz are called infrasound, and those above 20,000 Hz are called ultrasound. Different animals have varying audible ranges; for example, dogs can hear higher frequencies than humans, while elephants can perceive lower infrasound frequencies. The analysis of sound frequencies is fundamental to many fields, including acoustics, music, telecommunications, and audio engineering. Understanding äänitaajuuksiin allows for the manipulation, recording, and reproduction of sound with precision.
