DualSense has a built-in microphone that gamers can use to communicate online without the need for a headset. However, its new haptic feedback can potentially result in unwanted noise during gameplay to interfere with or distort the player’s voice. Sony Interactive Entertainment has apparently found a solution to silence this noise for clean communications.
According to a patent released earlier today, Sony has found a way to use artificial intelligence to cancel out noise components in a signal “created by haptics or other electronic components such as those found in computer game controllers ”.
The patent further notes that these haptics can create engine sound noise which “may be difficult to remove or cancel because it can be broadband with a changing signal characteristic over time.”
However, with machine-based learning algorithms, Sony can create a system to “generate an estimate of magnetic motor noise, and then use the estimated magnetic motor noise as a reference signal with noise cancellation technologies to reduce, cancel, delete or delete it. of the subject’s signal. “
Basically what Sony is trying to do (or have done) is first to store the original signal which includes noise such as that created by the rumble motor of the DualSense haptic sensors. AI then takes over and generates a second signal which replicates the original signal but without noise components. The system then uses the second reference signal to remove “at least some of the noise” from the original signal.
This entire process will need to be done on the fly to ensure that gamers can continue talking into their DualSense microphones without noise or static electricity.
Note that DualSense already offers a way to eliminate crosstalk and unwanted room noise. A linear array of several built-in microphones works in tandem to identify the player (user) and then exclude sounds produced by the surrounding environment.
