Anything you hit makes a vibration. Vibration=Sound.
I guess it depends how hard you hit the object (in this case metal) you will be able to hear the sound. But yes, they do make a high pitched sound when you hit them (some so high pitched you will never be able to hear them).
pleasant sound? softness and low pitch unpleasant sound? loudness and low pitch
Pitch is only a componet of any sound. It represents the frequency of the sound, normally expressed in hertz (number of waves in a second). Low frequeny sounds are bass, thunder, foghorns, etc. High frequency sounds are screeches, bird whistles, breaking glass, etc. People's voices are in between high and low (normally 400 to 1000 hertz). Other components of a sound are amplitude (how energetic or loud the sound is) and wave envelope (wave shape).
Amplitude is how loud it is. So a soft sound would have a small amplitude. Frequency is the pitch of the sound. High sounds have high frequency. Wavelength is the type of sound. Music wavelengths are in harmony. Changing the wavelength gives us the different words etc that we make.
In sounds with higher pitches, the compressions that make up the sound are closer together; when the pitch is lower, they are farther apart. The wavelength of a sound, which is the distance from one compression to the next, is the speed of sound divided by the sound's frequency (pitch).
The form of energy that is not conducted by most metals is sound because if you want to test that you would have to clank it together and it would not make a sound.
high pitch meows
whistling in a high pitch voice. they also make quiet bubbling sounds
because they never hit puberty
It makes a medium to high pitch 'oo' sound that may be drawn out to last for several seconds.
a high pitched sound
How tight the string is being pulled, like if you let it really lose it would make a very low sound, but if you pull it high it would make a very high sound.
When a timing belt is going bad it can make a high-pitched screeching sound. It can sound like a high-pitch whirring noise. Not all timing belts make a noise when they are worn or going bad.
Squirrels make a chattering sound and also they make a hissing sound when they are angry. They make a sound like a dog barking, only it is a really high pitch.
a high pitch
A little "chick chick" noise
