Question

how does the pitch of a sound depends on the frequency?​

Answer 1

Explanation:

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.

Answer 2

Question:

how does the pitch of a sound depends on the frequency?​

Answer:

Loudness of Sound:

• This phenomenon of a sound depending 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.

• The table given below gives us data for various sources of sound.

• The loudness of a sound wave is determined by its association with the amplitude, all types of waves have a certain amplitude.

• For example, a height of a wave on a calm ocean will be less than 1 foot whereas good surfing waves might be 10 feet or more in amplitude.

• During a storm, the amplitude might increase to 40 to 50 feet.

Pitch of Sound:

• 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 high-pitched sound whereas roaring of a lion is a low-pitched sound.

• The Voice of a woman has a high pitch than that of a man.

Difference between Pitch and Loudness:

• 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 individuals.

• The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.

• Amazingly, many musicians, who have been trained are capable of detecting a difference in frequency between two separate sounds that are as little as 2 Hz.

Loudness:

• Loudness is defined as the property of sound which is used for differentiating between the loud and faint sound

• Loudness is dependent on the energy received by the ear in unit time  

• Loudness is independent of the change in frequency

Pitch:

• Pitch is defined as the characteristic of sound which is used for differentiating between the shrill and flat sound.

• Pitch is independent of the energy received by the ear in unit time

• Pitch is dependent on the change in the frequency. As the frequency increases, the shrillness of the sound increases
