Systems and methods for verifying participation in a meeting using sound signals

A system for verifying the presence of an attendee at an education session, comprising:

• one or processors;
• and
• a memory in communication with the one or more processors and storing instructions that, when executed by the one or more processors, are configured to cause the system to:
• provide, by a verification device and to a leader device, information for a codified sound, wherein the leader device is located in a substantially enclosed space in which an education session is held, and wherein the codified sound represents a leader code;
• emit, by the leader device, the codified sound;
• receive, by a computing device, a sound signal associated with an attendee;
• determine, by the computing device, an attendee code from the sound signal received by the second device;
• and
• determine whether the attendee code matches the leader code.
