We call that type of wave longitudinal, like this:But people show sound as "up-down" waves because it is easier to show that way.Audio SpectrumA low frequency of vibration has a low pitch and makes a deep sound, like a growl.A high frequency has a high pitch, like a whistle....
This happens because the sound waves have vibration(振动). In (5)s___, there are names for different sound waves. When the sound vibration is (6)s___, we call this a low-pitch (音调) sound. But when the sound vibration is fast, we call this a high-pitch sound. Pitch (7)d__...

This happens because the sound waves have vibration.In science there are names for different sound waves. When the sound vibration(振动)is slow,we call this a low-pitch(低音) sound. But when the sound vibration is fast, we call this a high-pitchsound. Pitch describes how high or low a...
In sound waves, pitch is the frequency of sound and volume is the intensity of sound. Explore the parameters of sound, the definitions of amplitude, intensity, and frequency, and the acoustic range. Sounds and Their Parameters Are you a musical person? Do you have perfect pitch? If I pla...
Apart from amplitude, another thing worth noting about sound waves is their pitch, also called their frequency. Soprano singers make sound waves with a high pitch, while bass singers make waves with a much lower pitch. The frequency is simply the number of waves something produces in one secon...
sound wave 美 英 na.音波;声波 复数:sound waves 权威英汉双解 英汉 英英 sound-wave n. 1. 声波a vibration in the air, in water, etc. that we hear as sound
Therefore, vibration waves generated by the cast iron plate are transmitted to the resonance cavity of the clock to generate resonance, and sound playing tone of a high-pitch area of the piano is improved.林建忠黄苏东
The pitch of a sound is directly related to the frequency of the vibrations of its waves. People with excellent hearing can hear very low sounds, vibrating about 20 times per second, all the way up to high pitches with frequencies of 20,000 vibrations per second. Other animals can hear ...
Well, there is a direct relationship between frequency and pitch and between amplitude and loudness. Specifically, the more sound waves a sound produces, the higher the pitch. Meaning if a sound has a high frequency, it will produce a high-pitched, shrill sound, while sounds with a lower ...
