A sleep assistance device is provided-for, including a housing, a contactless biometric sensor, a processor, memory, and a speaker. The processor may detect a user's sleep state by reading signals from the contactless biometric sensor based on at least one of a detected change in heartrate, body movement, or respiration. The processor may also arrange a soundscape including individual sound records representing sounds associated with the selected soundscape based, at least in part, on the detected sleep state of a user.
