Shorter prongs produce higher pitch (frequency) sounds than longer prongs. Long prongs will bend more readily and therefore tend to vibrate at a lower frequency when struck. Volume, or loudness, is related to the strength, intensity, pressure, or power of the sound.Whether you hear a sound with a high or low pitch depends on how frequently the pressure waves hit the eardrum and cause it to vibrate. The faster the eardrum vibrates, the higher the pitch you hear; the slower it vibrates, the lower the pitch you hear.Volume (amplitude ) – shown by the height of the waves displayed. The larger the amplitude of the waves, the louder the sound. Pitch (frequency) – shown by the spacing of the waves displayed. The closer together the waves are, the higher the pitch of the sound.

How do vibrations affect the pitch of a sound?
Whether you hear a sound with a high or low pitch depends on how frequently the pressure waves hit the eardrum and cause it to vibrate. The faster the eardrum vibrates, the higher the pitch you hear; the slower it vibrates, the lower the pitch you hear.
How changes in sound waves affect pitch and volume?
Volume (amplitude ) – shown by the height of the waves displayed. The larger the amplitude of the waves, the louder the sound. Pitch (frequency) – shown by the spacing of the waves displayed. The closer together the waves are, the higher the pitch of the sound.

What affects the pitch and volume of sound?
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.
What is the relationship between vibrations and volume?
Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations. Sound vibrations can be transferred from one material to another.
What kind of vibration makes a high pitched sound?
Higher pitched sounds produce waves which are closer together than for lower pitched sounds. (Think of the slinky – if you produce waves rapidly they will travel quite close to each other, thus demonstrating a higher pitched sound.)
How can we change the pitch of sound?
Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune. The density of a string will also affect its frequency. Remember that dense molecules vibrate at slower speeds.
What affects volume of sound?
Sound occurs when energy causes air particles to move closer together and further apart. The closer the particles get or the further apart they get, the greater the sound’s amplitude. Sound amplitude causes a sound’s loudness and intensity. The bigger the amplitude is, the louder and more intense the sound.

Pitch and Frequency – The Physics Classroom
As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the …

10.3 Characteristics of a sound wave – Siyavula
The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. In …
Does pitch affect volume?
A high pitch (>2kHz) will be perceived to be getting higher if its loudness is increased, whereas a low pitch (<2kHz) will be perceived to be going lower with increased loudness. Sometimes called “Stevens’s rule” after an early investigator, this psychoacoustic effect has been extensively investigated.
What is vibration in sound?
Vibration is the backward and forward movement of a body. Sound is caused by vibration that makes particles in the air form sound waves. A damper is used to reduce vibration. Vibration is the backward and forward movement of a body.
What is the difference in pitch and volume?
Volume is a relative measure of a sound, which can be arranged from the lowest to the highest with respect to auditory sensation. The lowest possible value is quiet. Pitch is the lowness or the highness of the sound which is determined by the frequency of the noise. Loudness is affected by the pitch, and vice versa.

How do sound waves change with volume?
When we increase the volume of a sound, the amplitude of the wave is increased. The frequency of a wave is related to its pitch. If the pitch is high, then the frequency of the wave is high.
How is the pitch of sound related to the frequency of sound waves?
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.
What happens when pitch increases?
Pitch of sound depends upon frequency , so when pitch gets higher frequency f also becomes higher , now we have ,wavelength of sound λ∝1/f (for constant speed of sound in a medium) ,hence wavelength decreases i.e. frequency and wavelength go through a change when pitch gets higher .
What factors affect the pitch and loudness of the sound produced by the rubber bands?
Different rubber bands will produce different resonant frequencies, depending on their thickness or width, and how tightly they are stretched. Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.
Which of the following does pitch depend in vibration?
EXPLANATION: The Pitch of a sound depends on its frequency.
What causes different pitches in sound?
Pitch. The sound an object makes changes depending on how fast it is vibrating. When an object vibrates quickly, high-pitched sounds are heard. Low-pitched sounds come from things that vibrate more slowly.
Why does the pitch of the sound become high?
Sounds are the result of air vibrating, and if they’re reproduced at, say, twice the speed that they were originally recorded at, the vibrations hit our ear twice as many times per second – i.e. twice the original frequency, which makes them sound higher in pitch.
What happens to a sound as the vibrations of an object increase in strength?
This extra energy causes the string to vibrate more, which helps it move more air particles for a longer time. A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.
What is pitch and how does it change?
Pitch is related to frequency. Changing the number of vibrations per second changes the pitch. The pitch that a particular tuning fork generates depends on the length of its prongs. Each fork is stamped with the note it produces (e.g. A) and its frequency in Hertz (e.g. 440 Hz).

What happens to the sound an object makes when the speed of vibrations decreases?
Explanation: The vibration speed of an object is directly proportional to the pitch of an object. When the speed of vibration increases in an object, the pitch also increases. Similarly, when the speed of vibration decreases or slows down, the pitch becomes lower.
What three factors affect the pitch of a sound?
Factors affecting the pitch of sound
Pitch of the sound depends on the frequency of the sound wave. The pitch is affected by the source of production of sound wave. It also depends on the shape of the medium in which it travels. It does not depend on the properties of the medium.
