Zusammenfassung:	A method and beverage container assembly for determining a level of liquid in a beverage container having a lid removably attached thereto. The beverage container assembly including a sensor configured to measure sound waves in the beverage container assembly. A processor is electronically coupled to the sensor, and to memory provided with executable instructions for causing the processor to determine the level of liquid. The executable instructions, when executed by the processor, cause the processor to receive a sound wave measurement from the sensor, obtain a frequency characteristic of the sound wave measurement, and obtain reference information regarding a set of characteristics of the beverage container assembly. The processor may determine the level of liquid in the beverage container assembly based on the frequency characteristic and the reference information.
