-Generally speaking, latency is the difference in time between cause and effect. In human-computer interaction (HCI), latency is the time that passes before a user perceives the reactions to his actions. The perception is not limited to one channel but can be auditory, visual or haptic in nature [1].+Generally speaking, latency is the difference in time between cause and effect.

The perception is not limited to one channel but can be auditory, visual or haptic in nature [1].
  
 High latency leads to poor performance and user experience in the HCI[2, 3]. Video games are also affected by these negative effects. Players score fewer points, need more time to work on certain tasks, or can not solve certain tasks at all [4, 5]. High latency leads to poor performance and user experience in the HCI[2, 3].

 The sounds of a game are important to how users feel while playing and how well they perform in-game. Therefore, developers have placed a steadily increasing focus on audio and sounds in games[6]. The sounds of a game are important to how users feel while playing and how well they perform in-game.

-Since the proliferation of wireless headphones there has been a discussion on the differences between wired and wireless [7]. Most wireless headphones use Bluetooth, a short-range communication method. In order to send the sound to the headphones, Bluetooth compresses the data before sending it and then unpacks it afterwards to play the sounds [8, 9].  +Since the proliferation of wireless headphones there has been a discussion on the differences between wired and wireless headphones [7].

-An already existing 3d game will be changed by adding sound to all enemies and changing the mechanics slightly. Afterwards, in a second version of the game a delay will be added to all sounds. +This work investigates if and how auditory latency impacts user experience and performance. 
  
-To test whether/how this influences users, a study is then carried out where the participants play the same game once with and once without audio latency. To gather the data we will log the scores and the time enemies survive. Additionally, a questionnaire will be used to measure game experience. 
  
-To evaluate the quantitative data differences statistical tests will be used. The goal is to determine if and how latency on audio affects the user.
