= Duplex perception
{wiki=Duplex_perception}
Duplex perception refers to a phenomenon in auditory perception where a person can simultaneously perceive two different sound streams. This can occur when a single auditory input can be interpreted in two distinct ways, often due to conflicting information or overlapping sounds. A common example of duplex perception is found in certain types of speech sounds or auditory illusions, where a listener hears one sound, while at the same time, they may also sense an underlying or secondary sound that is either masked or obscured by the first.
