Have you ever wondered what sounds you would hear through a vacuum? We all know that sound cannot travel through a vacuum in space, but what about a vacuum here on Earth?
Well, the truth is that there won’t be much sound to hear through a vacuum cleaner. When you turn on a vacuum, the motor creates suction that pulls air and any small particles and debris along with it. This process leaves very little air inside the vacuum, which means that there is nowhere for sound waves to travel.
Even if you were to put your ear up to the hose or the body of the vacuum while it’s running, you won’t hear much. The few sounds that you may pick up will likely be muffled and distorted due to the lack of air to carry and amplify the sound waves.
However, if you were to put a microphone inside the vacuum, you might be able to pick up some interesting sounds. The sound of the motor running, the mechanical movements of the vacuum’s parts, and any loose debris being sucked through the hose may all be audible through a microphone.
It’s important to note that putting a microphone inside a vacuum can be dangerous and should not be attempted unless you are a trained professional. Vacuum cleaners are designed to be airtight and can create a vacuum that can be harmful to both humans and animals.
In conclusion, there isn’t much to hear through a vacuum cleaner due to the lack of air to carry sound waves. While you may be able to pick up some sounds with a microphone, it’s not advisable to attempt this without proper training and safety precautions.

Frequently Asked Questions for “What Do You Hear Through A Vacuum?”
1. Can sound waves travel through a vacuum?
Yes, technically sound waves can travel through a vacuum, but they would not be audible to human ears. Sound waves require a medium to travel through, such as air, water, or solid objects. In a vacuum, there is no medium for sound waves to propagate, and therefore, they cannot be heard.
2. How do scientists study sound in a vacuum?
Scientists can use specialized equipment such as vacuum chambers to simulate a vacuum environment. They can then introduce sound waves or vibrations and measure the effects of the sound on various materials or objects. This type of research is important for understanding how sound behaves in different environments and can have applications in fields such as aerospace or acoustics.
3. Why do some people claim to hear sounds or voices in a vacuum?
Some people may claim to hear sounds or voices in a vacuum due to the phenomenon known as auditory hallucinations. This is when a person perceives sound without an external auditory stimulus. In a vacuum, without any ambient noise, a person’s brain may create or amplify sounds that are not really present. However, this is not a common occurrence and should not be relied upon as evidence of sound transmission through a vacuum.
4. Could sound be used as a means of communication in space?
No, sound cannot be used as a means of communication in space. As mentioned before, sound waves require a medium to propagate through, and space is a vacuum with no medium for sound to travel through. Instead, communication in space relies on other forms of electromagnetic radiation, such as radio waves or light.
