Weber's Law
"We perceive differences on a algorithmic, not linear scale...not the amount of change but percentage of change that matters" - Hank Green
Weber's law states that the level of intensity a stimulus changes, the faster, easier it will be to detect a difference in a change.- Credit
If something is very loud, it needs to have more of a difference in a change to be noticed. - Credit

Signal detection theory
The context - place and situations - in which a person will be able to detect a weak stimulus. - Credit
Page 3
Sensory adaptation
Your senses adjusting to a stimulus that is consistent. - Credit
