The frequency of a sound wave determines what people hear as pitch. A higher frequency has a higher pitch, and a lower frequency is heard as a lower pitch. The frequencies that humans can hear range from 20 to 20,000 Hertz.Know More
Frequencies below 20 Hz are called infrasound, and those above 20,000 Hz are ultrasound frequencies. Animals like dogs and dolphins can hear at lower and higher frequencies than humans. For example, dolphins hear frequencies between 0.25 and 200,000 Hz.
A wave's frequency is defined as the rate at which a particle vibrates through a medium or material. Hertz is the unit of measurement used for frequency; 1 Hertz is equal to 1 vibration per second.
Loudness, which is another component of sound waves, is determined by a sound wave's amplitude. A large amplitude represents a louder sound.Learn more about Optics & Waves
Pitch is determined by the frequency of a wave, and frequency is the combination of wavelength and speed at which the wave is traveling. Sound has a constant speed of 343 meters per second, so wavelength dictates pitch. The longer a sound's wavelength, the lower the pitch of that sound.Full Answer >
Sound is generally classed as ultrasonic when its frequency exceeds 20,000 hertz. This is the upper range of humans' ability to perceive, though the ultrasonic range of frequencies extends upward into the millions of hertz.Full Answer >
The difference between pitch and volume is that pitch is determined by the frequency that sound waves vibrate at while volume measures how loud or soft sound is. Combined with timbre, pitch, measured in hertz, and volume, measured in decibels, comprise the three components of sound.Full Answer >
Pitch refers to the frequency of a sound, while loudness refers to the size or amplitude of the sound. Every sound has both a specific pitch and loudness.Full Answer >
