Cooling and noise control for head-mounted device

Abstract:

A head-mounted device can effectively manage heat while also managing noise output levels in a manner that preserves the user's desired experience with the head-mounted device. The head-mounted device can manage sound levels of a cooling system based on detected a sound level of ambient noise in a vicinity of the head-mounted device. For example, the head-mounted device can operate a fan at a speed that produces noise at a sound level that is low enough to be masked by the ambient noise perceived by the user. By further example, the sound level of a cooling system can be based on a sound level of a speaker of the head-mounted device providing audio to the user. By further example, other operational parameters of a cooling system can be controlled to manage noise at a sound level that is sufficiently low.
