Abstract: A system for maintaining confidentiality of vocal audio is provided. The system includes a shell defining an internal volume and configured for wearing on a face of a user, wherein the shell comprises a sound absorbing material, a first sound sensor configured to receive voice audio, a second sound sensor configured to receive at least attenuated voice audio, and a computing device. The computing device is configured to receive a selected confidentiality level, receive audio data from the first sound sensor and the second sound sensor, obtain an exit sound pressure level of the attenuated voice audio based on input from the second sound sensor obtain an ambient sound pressure level associated with ambient sound, determine a maximum desired distance of the attenuated voice audio based on the exit level and the ambient level, and provide a notification to the user that the selected confidentiality level cannot be assured.

Abstract: A system for facilitating compliance with voice call restrictions for a defined space includes a communication device and a sound pressure level sensor. The communication device includes a processor and is configured to access a communications network associated with the defined space to transmit and receive audio data. The sound pressure level sensor is configured to detect sound levels received by the communication device.
