As a sound source approaches, the pitch you hear becomes higher. This effect is known as the Doppler shift, where sound waves are compressed as the source moves closer, resulting in a higher perceived frequency.
No, you do not have to be directly in front of an object to hear a sound. Sound waves can travel in all directions, so as long as you are within range of the sound source, you will be able to hear it.
If you're looking at the source of the sound, then you don't even need sound to identify it. So yes, it is easier.
When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
In order to hear a sound, three things are needed: a source of sound producing vibrations, a medium such as air or water for the vibrations to travel through, and the ear to receive and interpret the vibrations as sound.

Check whether your speakers are connected to your default soundcard.

Too much sound from another source that you can't hear what you want from the desired source. Like having the TV so loud you can't hear the person next to you speak.
You would then hear some sound sooner than others.

The Doppler effect alters how we hear sound by changing the pitch or frequency of the sound wave when the source of the sound is moving towards or away from us. If the source is approaching, the frequency increases, resulting in a higher pitch; if it is moving away, the frequency decreases, leading to a lower pitch.
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.
No, when you hear sounds, the vibrations from the source of the sound travel through the air as waves of pressure. These waves cause the molecules in the air to vibrate, but the molecules themselves do not travel from the source of the sound to your ears.
