dogs can hear higher pitches. it doesn't "mean" anything. it is normal. dogs have better hearing.
the object isn't vibrating in a range for humans to hear.
You can make a sound wave using a vibrating object by causing the object to move back and forth rapidly. This movement creates changes in air pressure, which travel as sound waves through the air to your ears, allowing you to hear the sound.
When an object vibrates in the air, it creates sound waves. These sound waves travel through the air and reach our ears, allowing us to hear the sound produced by the vibrating object.
When an object vibrates, it causes the air around it to also vibrate. This vibration creates sound waves that travel through the air and reach our ears, allowing us to hear the sound produced by the vibrating object.
It can be thermal energy if it is the atoms vibrating in a solid material. If the vibration is large enough it can cause acoustic energy, if the vibrating object is coupled to the atmosphere. If an object is vibrating in a magnetic field it can give off electromagnetic energy.
they cant hear but they can hear vibrating so they seem to know that its its enimie
An object must be vibrating in order to produce sound. This vibration creates a disturbance in air particles, which travels in the form of sound waves to our ears, allowing us to hear the sound.
its the vibrating of mollecules. That's why in space, you cant hear anything because there are no mollecules to vibrate.
Human ears can only hear (i.e., detect vibrations) in a range of about 20-20,000 vibrations per second. A pendulum will usually vibrate at much less than 20 vibrations per second. But please note that a vibrating object (such as a plucked string) may also produce secondary vibrations, other than the main frequency.On the other hand, a vibration must also be strong enough, in order to be heard.
when we use a pointed object it will hurt the eardrum and we cannot hear
In a telephone, the electronic components, such as the speaker or the vibrating motor, vibrate to produce sound waves that are then converted back into sound that you can hear. When you receive a call, the vibrating motor is activated to create the ringing sound you hear.
It's most likely to do with the type of walls which are in the house. If the walls are weak/thin, then you will be able to hear what is happening on the other side.
