A system and method to defog and/or defrost a sealed sensor system housing window to improve transmission of an electromagnetic wave through the housing window. The system includes at least a heater provided in a sealed sensor system housing to emit heat into the housing. The heat is then distributed via convection promoted by a moving component of the sensor system, a fan, or a combination of both. Additionally or alternatively, heat may be transferred to the housing window via conduction. A controller can be configured to activate or deactivate the heater based on a determined or predicted state.

Techniques for cleaning and calibrating a microphone are discussed herein. For example, a computing device can implement a microphone component to operate a speaker adjacent to a microphone to cause removal of an obstruction (e.g., rain, mud, dirt, dust, snow, ice, animal droppings, etc.) on or near the microphone. The microphone component can also or instead cause the speaker to output a frequency for testing operation of the microphone. By implementing the cleaning and/or calibrating techniques described herein, foreign particle(s) of varying size and type can be dislodged from an area near the microphone to improve performance of the microphone.
