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.

Why do windows vibrate when sound hits them?
Sound waves propagate as a longitudinal waves. Any wave has some frequency and some wavelength. More the frequency more energy it possesses and hence its intensity increases so when such a wave hits something you can sometimes see the object vibrating. Also sound waves do not travel in space.
How low or high a sound is its?
The pitch of a sound is determined by its frequency. A high-pitched sound has a higher frequency, while a low-pitched sound has a lower frequency. The unit of measurement for frequency is hertz (Hz).
What sound is decided by the frequency of its vibrations?
The pitch of a sound is determined by the frequency of its vibrations. A higher frequency produces a higher pitch sound, while a lower frequency produces a lower pitch sound.
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.
Which characteristic of sound depends upon frequency?
frequency is the pitch of a sound
Is an echo a high or low frequency sound?
An echo can be either a high or low frequency sound, depending on the original sound that it reflects. The frequency of an echo is typically the same as the frequency of the original sound wave.
What characteristic of sound is most closely related to its frequency?
The pitch of sound is most closely related to its frequency. A higher frequency sound wave produces a higher pitch sound, while a lower frequency sound wave produces a lower pitch sound.
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.
What is formula for the frequency of sound?
The formula for the frequency of sound is: frequency = speed of sound / wavelength. The speed of sound in air is approximately 343 meters per second at room temperature.
What difference will you hear in a sound there is increase In the frequency?
An increase in frequency will result in a higher pitch sound. The sound will be perceived as being "higher" or "squeakier" compared to a lower frequency sound.
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.
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
