Exemplary embodiments of the present disclosure are directed to various components of a system for monitoring and/or tracking a user's performance during an activity involving an instrument that is swung. Exemplary embodiments can include a sensor module configured to be secured to and/or embedded within the instrument. The sensor module can detect a swing event and/or an impact between the instrument and an object and can generate pressures waves that propagate through air. The pressure waves can include information or represent information about a use of the instrument and can be detected by an electronic device associated with the user, which can display the information, process the information, and/or transmit the information to a remote system. The pressure waves can be modulated to encode information within the pressure waves.
