In modern cars there is usually an electric fuel pump, either actually in the tank or just nearby. That's probably what you're hearing.
it creates gaps in the air and then goes to your ear
Turn the ignition on and see if you hear a humming coming from the pump. If it is inside the fuel tank, you can hear it from the back seat.
after the first heart sound is made ventricles starts emptying.
The oxygen(rich)- and poor blood which are pumped in and out of the heart in the ventrical and atrium,with the help of mucsles, creates a sound (which is the sound that you hear)It is the blood getting pumped
if you mean when you put the key in the ignition to start it you hear a grinding sound then either your flywheel has a missing tooth (unlikely) or the starter is the one that needs replacement(most common) if you mean that when the car is started you hear a grinding sound and the car when gears are shifted it wont move then since it is a manual transmission i would look at the clutch housing.(throw out bearing ,spring compressor ect.) perhaps someone else may have other sugestions or ideas.
You will hear the fuel pump prime for about a second when when you turn the ignition key to the "on" position. It's a low buzzing sound.
may be a bad starter..... or if the engine is cranking with no start it could be the ignition wires
Open the driver side door. Turn the ignition switch to the 'auxiliary' position, then turn the ignition switch to the 'ON' position and back to the 'auxiliary' position four times. *This must be done fairly quickly. If you have done it correctly, you will hear a chime. Turn the ignition switch to 'OFF' position. Remove the key from the ignition. To program the transmitter, press any key within ten seconds. **If it worked, you should hear another chime. Close the door.

mute means no sound deaf means you hearing impaired( you cant hear anything)
it means when you hear a screeching sound whitch sounds like the sound of iron on stone.
make sure that ignition switch is completely turned off. turn key to acc position and listen for humming sound that lasts for about two or three seconds. if you do not hear that hum, your fuel pump is not functioning
Aud- is the root syllable of the infinitive 'audire'. It means to hear. That also is the meaning of the infinitive.
The opposite of "there" is "here."(The homophone hear means to detect sound).
Resounding means making an echoing loud sound.
Hear is a verb: hear, hears, hearing, heard.
Sound travels faster underwater, but this does not mean that divers hear better underwater. It just means that the sound is heard more quickly.
