Correct sound effect and wrong sound effect

Figure 1 - Amplitude and frequency represented as waves.

But if you stand in the ocean during stormy weather, the large incoming waves may be strong enough to knock you down! Just like the size and strength of water waves, the size, and strength of sound waves can have a big effect on what you hear. If you stand in still water and drop a pebble near your legs, it will cause a small ripple (a tiny wave) that does not affect you much. It might even help to think of sound waves like waves in an ocean. If the peak is larger, then the sound will seem louder.

As you can see in Figure 1, when the peak of the sound wave is smaller, the sound will be perceived as quieter. The amplitude of a sound wave can be thought of as the strength of the vibrations as they travel through the air, and it determines the perceived loudness of the sound. Higher frequency sounds have a higher pitch, like a flute or a bird chirping, while lower frequency sounds have a lower pitch, like a tuba or a large dog barking. Frequency is the speed at which a sound wave vibrates, and it determines the pitch of a noise. The two most important physical qualities of sound are frequency and amplitude.

In the vacuum of space, for instance, sounds cannot occur because, in a true vacuum, there is nothing to vibrate and cause a sound wave. One thing that many people do not realize is that sound waves have physical properties and are therefore influenced by the environment in which they occur. For example, if a branch falls off a tree and hits the ground, the air pressure around the branch changes when it hits the earth and, as a result, the vibration of the air produces a sound originating from the collision. Sound is produced when an object vibrates the air around it, and this vibration can be represented as a wave that travels through space. Our ability to hear is crucial for providing information about the world around us. In this article, we will explore how your brain gathers information from your ears and uses that information to determine where a sound is coming from. Creators of movies and video games use these cues to trick our minds-that is, to give us the illusion that certain sounds are coming from specific directions. If it hits both ears at the same time, it likely originated from directly in front or behind you. For example, if the sound hits your right ear first, it likely originated to the right of your body. Two of these cues are (1) which ear the sound hits first, and (2) how loud the sound is when it reaches each ear. Have you ever wondered how, with just two ears, we are able to locate sounds coming from all around us? Or, when you are playing a video game, why it seems like an explosion came from right behind you, even though you were in the safety of your own home? Our minds determine where sound is coming from using multiple cues.
