1. A method for measuring and communicating media exposure, the method comprising:

  • in response to a change of a volume setting of a user device after receiving, at the user device, data provided via a web page accessed by the user device;

    switching, at the user device by executing an instruction with a processor and based on the volume setting of the user device, from a second sound signal previously selected to be encoded with a code signal to a first sound signal to be encoded with the code signal, the first sound signal having a first duration, the first sound signal selected from a library of beacon sound signals stored at the user device, the library of beacon sound signals including beacon sound signals having different durations of a same type of sound; and

    after the switching from the second sound signal to the first sound signal, embedding, at the user device by executing an instruction with the processor, the code signal, which is encoded with an identifier associated with the user device and information identifying the accessed web page, into the first sound signal to determine an encoded first sound signal; and

    outputting the encoded first sound signal from the user device to a remote location for media exposure processing.
