Pitch, frequency and volume - Writing task
Science Resource Description
Pitch, frequency, and volume are three fundamental characteristics of sound that are essential in understanding how we perceive audio. The pitch of a sound is how high or low it seems to us. It is determined by the frequency of the sound waves; the higher the frequency, the higher the pitch we perceive. Frequency itself is measured in Hertz (Hz) and refers to the number of waves that pass a point in one second. Volume, on the other hand, is about the loudness or softness of a sound. It is determined by the amplitude of the sound waves; larger amplitudes mean louder sounds, while smaller amplitudes indicate softer sounds.
Sound is created when an object vibrates, setting air particles into motion and causing sound waves to travel through mediums such as air, water, or solids. These vibrations can be thought of as the heart of sound production. When we discuss pitch in relation to vibration, we're talking about the rapidity of these vibrations. Faster vibrations produce a higher pitch, while slower vibrations result in a lower pitch. The concept of pitch and vibration is integral to the production and perception of sound, influencing everything from the melody of a song to the tone of a spoken voice.
