Abstract
Methods, apparatus, systems, and articles of manufacture are disclosed to determine performance of audience measurement meters. An example apparatus disclosed herein is to cause an audio output device of a meter to emit an audio signal into an environment, the audio signal based on a test pattern including a first plurality of watermarks and cause an audio input device of the meter to collect data from the environment during emission of the audio signal. Additionally, the example apparatus is to determine whether a second plurality of watermarks decoded from the data match the first plurality of watermarks and based on a difference between the first plurality of watermarks and the second plurality of watermarks indicative of a fault, cause an alert to be transmitted to a device associated with an audience measurement company that issued the meter.
