Yes, sound is created when objects vibrate and transmit energy through the air as pressure waves. These waves travel to our ears and are interpreted by our brain as sound.
True. When energy is applied to make an object vibrate, it creates sound waves that we perceive as sound.
True. Sound waves are indeed an example of longitudinal waves. In a longitudinal wave, the particles of the medium vibrate parallel to the direction of wave movement. This is how sound travels through air, water, and other mediums.
False. Objects that vibrate more quickly actually have higher frequencies. Frequency refers to the number of vibrations per unit of time, so a higher frequency means more vibrations occur in a given time period.

The True Sound of the New West was created in 2001.

sound waves can only travel through particles as particles vibrate. this is why solids let sound pass easiest as the vibrations are passed on the easiest. in a vacuum there is no sound because there are no particles

Your voice is a sound, hence it is a vibration in the air, which is caused by a vibration in your vocal chords. This is true whether you are singing or speaking. It's a vibration, either way.
Yes, it's true. When sound waves enter the ear, they cause the eardrum to vibrate. These vibrations are transmitted through the ossicles (tiny bones in the middle ear) to the cochlea in the inner ear, where they are converted into electrical signals. These signals are then sent to the brain via the auditory nerve, allowing us to perceive sound.
Sound cannot travel through a vacuum, it needs a medium to travel through as its the vibration of particles that allows its energy to progress
True. Cilia are hair-like structures that protrude from the surface of cells and can beat or vibrate in a coordinated manner to help move substances or particles across the cell surface.
