Methods, apparatus, systems and articles of manufacture to implement selective suppression of audio emitted from an audio source are disclosed. Example methods disclosed herein include obtaining, at a portable device, data transmitted at a first time by a transmitter associated with an audio source, the data including reference audio data corresponding to a first audio signal to be output by the audio source at a second time after the first time, the data further specifying a time delay corresponding to a difference between the second time and the first time. Disclosed example methods also include generating, based on the reference audio data and the time delay, a suppression audio signal to provide to an audio output driver in communication with a speaker of the portable device to suppress the first audio signal when the first audio signal is output by the audio source at the second time.
