What is sound? How do we hear it? It makes sense that questions like this would cross our minds. Let's get more information on it. Sound is a wave that creates vibration. Sounds are made when objects vibrate. We can hear them as sounds. Sound can move through the air, water, wood, and any other solid object. To understand the pitch of the sound, first, we have to know what is the pitch of the sound. The pitch is the highness or lawless sound.
Pitch is measured in hertz. We can easily know how high or low the sound is. The pitch of sound depends upon the frequency of the vibrating body. In this topic, we will learn about sound waves, the high pitch of the sound, the types of sound, and the components of sound.
Pitch of Sound
What is the pitch of sound? Let us know about it in detail. When an object vibrates very loud, it makes a high-pitched sound. A high-pitched sound is also named a shrill sound. The pitch of sound can be high, medium, or low. The higher the pitch of the sound, the higher the frequency of vibration. The pitch of sound is measured by hertz. 1 Hz implies 1 vibration per second. It means 60 vibrations in 1 minute. For example, we can say that a bell in a temple makes a high pitch.
The pitch of the sound is determined by its amplitude. The pitch is increasing with the increase in frequency and decreases with the decrease in frequency. Also, the pitch of the sound is determined by its frequency. Interestingly, the pitch of a woman is higher than a man’s pitch.
Here, let us look at some examples of high-pitch sound and low-pitch sounds.
Pitch of Sound
The sound of pitch depends on the wavelength. High-pitch sounds have a short wavelength. There are three types of waves.
High pitches have a short wavelength.
Medium pitches have a medium wavelength.
Low pitches have a long wavelength.
Wavelengths can have low, medium, or high frequencies. There is a reverse connection between the pitch of sound and wavelength. We can understand with the help of the diagram below.
Length of Waves
Types of Sounds
There are three types of sounds:
Infrasound - A sound that has a frequency below 20 hertz is called infrasound. This sound occurs from light sounds like a waterfall, and slow-speed fans.
Sonic - The sound with a frequency between 20 to 20000 hertz.
Ultrasound - The sound which has a frequency above 20,000 hertz is called ultrasound. These sounds have a very high pitch. It is mainly used for medical purposes.
Components of Sound
The following are the components of sound:
Wavelength - The pitch of a sound depends upon the frequency. Frequency is related to wavelength. The higher the pitch of the sound, the lower the shorter the wavelength.
Pitch - Pitch is also called frequency. The SI unit of pitch is hertz.
Facts about the Pitch of Sound
The following are the facts about the pitch of sound:
Flies cannot hear any sound.
Elephants communicate with a lower pitch of the sound that humans cannot hear.
A cat can hear a higher frequency of sound than humans.
Humans hear sounds up to 17000 hertz
Children can hear at a higher frequency than adults.
When we speak, in addition to the words we use, we also convey meaning through the gestures and sound patterns we make. These patterns control our daily communication, from the basic rhythms of speech to the precise timing qualities of a consonant.
Sound is a vibration that creates the sensation of hearing. The pitch of sound is a measure by which we can hear sound. Pitch can be high, medium, or lower. Hertz is a tool to measure the pitch of the sound. The best example of sound is music.
