I would suspect that sounds in the frequency range of the human scream (3-4 KHZ) could do this. However, any sound that accompanies another action that is scary will continue to trigger a fear reaction even when only the sound alone occurs. Think of the low-bass sound in Jaws each time the killer shark appeared. By the middle of the movie, you were probably afraid as soon as that music began. Consider also the sound of a car horn that preceded an auto collision you were in, and how that sound can instantly cause the fear and recollection of the collision.

Which characteristic of sound depends upon frequency?
frequency is the pitch of a sound
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
What does the high frequency of a sound wave determine?
The frequency of a sound wave determines the pitch. So if there is high frequency it means that the sound will also be high pitched. If it is low frequency that means the sound will be low pitched.
How does sound affect frequency?
The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.
Can you make a sound wave at a high enough frequency to convert it into light?
First of all, a sound wave is not a light wave. The frequency is not the only difference - it is quite a different type of wave. A wound wave might somehow INDUCE the creation of light waves (I don't know, it is just a possibility), but the sound wave ITSELF will not become a light wave. Second, the frequencies of light are extremely high; I am not sure whether sound can made at such frequencies.
What does the pitch of a sound wave depend on?
Timbre of the sound. It is related to the frequency of the fundamental frequency and a combination of overtones.
The pitch of a sound wave is its?
Its' frequency.
Does the pitch of sound depend on the frequency of the sound waves that produce it?
yes, the pitch of sound does, in fact, depend on the frequency of the sound wave.
Is sound a tone?
A tone is a frequency and sound is a frequency therefore a sound is a tone.
What property of sound determines the pitch of a sound?
It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
How does sound frequency change?
the frequency of a sound can change depending on how fast the source is vibrating
Describe something that can affect the pitch of sound?
The pitch of sound depends on the sound's frequency. Frequency is basically the amount of waves the sound is producing. If there are many waves, "happen frequently", it is a high frequency. This is a high pitch. If the distance between the waves is large, it is a low frequency and a low pitch.
