The scenario shows that Lauren is one of the people who have the impact of the Cocktail party effect.
Psychoacoustic is the study of how the brain translates sound. Good knowledge of this mechanism is needed in sound engineering, wherewith proper manipulation, can produce very complicated sound effects. One important factor when processing sound is the brain translates two channels of sound information at once; which enters the left ear and which enters the right ear. Sometimes, this (thin) difference between the two signals presents new information associated with the composition of the two sound waves. In this discussion, we talk about stereophonic sound. When both signals arrive at the same time are called monophonic sound.
1. Environment
The sound of an instrument changes as a function of the environment. All initial reflections enter the Haas zone and give character to the "room" aspect of the instrument.
2. Coloration suppression
Two signals that come from the same sound source create phase differences interpreted by the brain. If this signal is heard through only one ear, it will sound unpleasant, whereas when heard through both ears it will create a pleasant effect.
3. Illusion of octaves
We have seen that when a note is played, fundamental frequencies and their harmonics emerge. The brain can reconstruct fundamental frequencies by only hearing its harmonics.
4. Cocktail party effect
The brain can listen to a specific signal between a set of overlapping sounds. For example, how many Lauren at the airport can hear the announcement, even though he was in a state of chatting with other passengers and in noisy environments.
