Abstract
In some examples, sound verification may include a speaker device that may be configured to transmit sound at a dynamic volume level and a listening device that may be configured to receive the sound and provide feedback to the speaker device based on the received sound. The primary transceiver device may be further configured to adjust the dynamic volume level based on the feedback provided by the secondary transceiver device.
