What are sound waves we can't hear called?
Sound waves that are too low or too high in frequency for the human ear to detect are called infrasound and ultrasound, respectively.
Sometimes you feel the vibrations from a sound source before you hear the source itself Why is this?
Sound travels in waves. Our ears register these waves and convert them into noise; however, our ears can only detect a very small range of sound waves. Many sound waves have a frenquency that is much too high or too low for our ears to "hear". If you've ever blown a dog whistle and made your pup yelp in pain while you couldn't hear a thing then you understand. The vibrations that you feel are low frequency sound waves which your body can feel but your ears can't hear. It is only when the higher frequency waves get to you that you hear the source.
What do you call a sound that you cannot hear?
Sound too low in frequency to hear (~<20Hz) is called infrasound. Sound too high infrequency to hear (~>20kHz) is called ultrasound.
At what waves can humans NOT hear?
Humans cannot hear ultrasonic (above 20,000 Hz) and infrasonic (below 20 Hz) waves. Ultrasonic waves are too high in frequency for the human ear to detect, while infrasonic waves are too low.
What are waves in the air caused by vibrations?
Waves in the air caused by vibrations are known as sound waves. When an object vibrates, it disturbs the surrounding air molecules, creating compressions and rarefactions that travel through the air as sound waves until they reach our ears, where they are perceived as sound.

What are waves with low frequency?
What kind of waves? Water waves? Sound waves? Low frequency water waves move the boat up and down slower. Lower frequency sond waves make a lower town, but if its too low the human ear can't hear it. Or maybe you are talking about Electric and Magnetism? You should give more info in the question. It is too general.

Why can you not hear the echo if you stand 20 meter away and shout towards it?
You are too close to the surface from which the sound waves are reflected. As a result you brain cannot distinguish between the original sound waves and the reflexted sound waves (the echo).

What name is given to the form of sound whose pitch is too low for humans to hear?
Infrasound is the name given to sound waves with a frequency below the lower limit of human audibility, around 20 Hz or less. These low-frequency sound waves can be generated by natural events like earthquakes or by man-made sources such as wind turbines.
Are there sounds we can not hear?
Human hearing is most effective in the range of about 20 Hz to 20,000 Hz. Slightly lower frequency sounds may be heard or "felt." Some sounds outside this range can be heard by some individuals. Some animals have a wider range of hearing, such as dogs who can hear higher pitched (higher frequency) sounds.
An earthquake is a fairly quiet shaking of the earth?
For humans it is, because most of the sound is at frequencies too low for us to hear.
What is the term for any sound that is too high for humans to hear?
The term for any sound that is too high for humans to hear is "ultrasonic."
Why is that you can not hear at a great distance?
Sound waves dissipate as they move through the atmosphere. How far sound waves travel or how fast these waves dissipate is dependent on but not limited to the initial magnitude of the source creating the propagation of sound waves. For example, throw a pebble into a body of water, the waves generated are similar to sound waves. these waves are small and dissipate rather quickly. Now throw a boulder into the water, these waves are much larger and take longer to dissipate as they move through the body of water. The reason you can not hear at long distances is due primarily to two factors. 1. the sound generator is too small or the listening devise (in this case your ear) is not sensitive enough or the sound wave has dissipated completely.
