The present disclosure provides systems and method for determining a background noise level. The device may receive audio from two or more microphones. The audio may include a first signal and a second signal, such that each microphone receives its own signal. The time, loudness, frequency of the first and second signals may be compared to determine the source of the audio, such as whether the audio is the user's voice or background noise. Based on the source of the audio, the audio may be suppressed to reduce false estimations when calculating the background noise level.

The present disclosure provides systems and methods for progressively transitioning the playback volume based on a background noise level. The device may have a predetermined quantity of volume levels between a minimum volume and a maximum volume. The volume levels may be spaced by predetermined increments, such that there is a predefined difference between adjacent volume levels. A digital gain may be used to adjust the volume level and an analog gain may allow for the playback volume to be adjusted to an amount between adjacent volume levels. The playback volume may progressively transition within the predefined volume levels by an amount less than the predetermined difference between adjacent volume levels. This smaller amount may be the analog gain.

Automatic progressive transition of volume adaptation to environmental noise

Various arrangements for monitoring and controlling operation of a HVAC system are provided. Battery-operated temperature monitoring devices may be situated within the structure and connected with a network. A user command may be received that includes a selection of at least one of the battery-operated temperature monitoring devices. An offset may be calculated based on an evaluation of a first temperature reading of the selected battery-operated temperature monitoring device relative to a second temperature reading of the thermostat. The offset may be overridden when an override condition is present.
