Abstract
The present disclosure is directed to a gain control system that receives a signal and outputs a modulated signal. The signal modulation is based on a gain that is based on a detected distance between the gain control system and a user. The distance is detected with a ranging sensor which generates ranging data for a field of view, and then the gain control system analyzes the ranging data to identify the user, with a higher signal gain for the user at a greater distance and a lower signal gain for the user at a lesser distance.
