The word "via" is latin for "by way of". To say something traveled via air waves is to say that something was broadcast by radio.

How does sound happen?
By multiple vibrations in the air aka sound waves. An object which creates kinetic energy produces air pressure variations which are interpreted as sound by the brain via the ear drum and the nerves in the inner ear.
Can sound waves travel through air?
Yes sound waves can make a sound in the air
What is sound wave velocity?
Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.
Mechanical waves are classified according to what?
Mechanical waves transfer energy via oscillations in a medium of some kind. That said, we classify mechanical waves according to the direction of the oscillations of the media. There are thee. Surface waves travel at the junction of two mediums, like water waves travel at the junction of water and air. Longitudinal waves travel in the same direction as the wave is moving, and sound moves this way via compression and rarefaction of the media. Picture the forward and back motion of a speaker cone moving air to create sound. Transverse waves see the medium moving side to side, and a long, flexible spring will do this if it is gently stretched and held at one end while the other end is wiggled right and left.
What do you hear when 2 sounds waves cancel each other out?
When two waves interact via deconstructive interference, then you would hear nothing if you stood in that exact spot. If two waves interact via constructive interference, then you would hear a sound that is the sum of both waves.
Is the basilar membrane receive sound waves via air?
I think basilar membrane is the receptors for sounds stimuli.
How do you make a model on reflection of sound?
Sound is just waves within a medium (Air), you could quite effectively create a model via a tub of water and show waves bouncing off the sides, sound will have a similar propagation to the water waves.
Do sound waves vibrate the air?
No. Vibrating air IS sound waves. With no atmosphere (no air, like in space), there are no sound waves.
How does sound travel from instruments to your ears?
Sound creates waves in a material- compression waves. These waves are transmitted through the atoms/molecules in the material to the receiver. The denser a material is, the more effectively sound may travel; this is because the sound waves are transmitted more easily through the tightly packed molecules.
When two men walk on the moon they cannot hear each other why?
Sound waves travel via vibrating molecules in air or other materials (water for example). On the Moon there is no atmosphere and as such nothing for sound waves to travel in.
When two men talk on the moon they cannot hear each other why?
Sound waves travel via vibrating molecules in air or other materials (water for example). On the Moon there is no atmosphere and as such nothing for sound waves to travel in.
An insect that produces waves in the water and in the air what can these air vibrations produce?
These waves in the air are called Sound waves, waves that vibrate in the air and if your hearing is good these vibrations will vibrate our ear drums and cause us to hear them as noise or sound.
Can sound waves travel through air?
Yes sound waves can make a sound in the air
How does sound happen?
By multiple vibrations in the air aka sound waves. An object which creates kinetic energy produces air pressure variations which are interpreted as sound by the brain via the ear drum and the nerves in the inner ear.
What are the 2 main type of waves?
Waves in Air give a great example: they occur in two types - compression [compressed Air] and rarefaction [expanded or decompressed Air] Waves.
What is sound wave velocity?
Sound waves are longitudinal waves in air. Velocity of sound waves in air at NTP = 332 m/s.
Does the brain communicate with in itself via the brain waves?
yes.
