The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.
I understand that amplitude determines volume and frequency determines pitch. What changes the quality of a sound? For example, an oboe, a violin, and the speaker in this video can all produce a sustained 440 hz A at the same volume. Why do they sound different?

- Good question. I think firstly it is to do with the shape of the wave. This will be determined by the features of the instrument (eg a violin tends...
- No, That graph is like a picture showing where MANY particles were at *ONE specific moment in time*. the x axis represents the "equilibrium locatio...
- If the velocity is the same, Then by rearranging V=(wavelength or lambda) / T (time period) Then, an increase in wavelength MUST cause a decrease i...
- We really just aren't made to. In order to hear a sound our eardrum must vibrate, and 20000 times per second is just too darn fast for it - the ene...
- By using a microphone you can convert the sound waves to an electrical signal and that can be displayed on an oscilloscope.
- To increase the amplitude makes the sound more intense, or louder if you may.
- Yes. Energy is proportional to amplitude squared

- Difference Between Pitch and Loudness
The phenomenon of sound depends on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud.It is directly proportional to the square of the amplitude of vibration. If the amplitude of the sound wave becomes double, then the loudness of the sound will be quadrupled.It is expressed in decibel (dB).Sounds above 80 dB becomes noise to human ears.This depends on the frequency of vibration of the waves.If the frequency of vibration is higher, we say that the sound is shrill and has a high pitch. On the other hand, if the sound is said to have a lower pitch then it has a lower frequency of vibration.A bird produces a high-pitched sound whereas roaring of a lion is a low-pitched sound.The voice of a woman has a higher pitch than that of a man.These two phenomena seem to be the same sometimes, but they are not exactly the same. They differ on the basis of their tone quality. The pitch of a sound is our ear’s response to the frequency of sound. Whereas loudness depends on the energy of the wave. In general, the pitch is the reason behind the difference in voice quality of different indivi...
Jan 11, 2021 · How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for humans to hear.
Dec 28, 2020 · In psychoacoustics, the pitch of a sound is essentially a description of the frequency of the sound. High pitch means high frequency, and low pitch means low frequency. Pitch can also be described as the quality of a sound that allows you to label it as “higher” or “lower” to your ear.
Jan 16, 2024 · The pitch of a sound is determined by the frequency of the sound waves. Frequency, measured in hertz (Hz), represents the number of cycles or vibrations per second. A higher frequency corresponds to a higher pitch, while a lower frequency corresponds to a lower pitch. Definition of Frequency.
frequency, pitch, tone. The frequency of a sound wave is called it pitch. High frequency sounds are said to be "high pitched" or just "high"; low frequency sounds are said to be "low pitched" or just "low".
