Comparison of the population representation of multiple sound sources for models with additive and multiplicative frequency integration. Brian J. Fischer Charles H. Anderson José Luis Peña 10.1371/journal.pone.0008015.g010 https://plos.figshare.com/articles/figure/_Comparison_of_the_population_representation_of_multiple_sound_sources_for_models_with_additive_and_multiplicative_frequency_integration_/545451 <p>(A,B) The population response to two simultaneous spectrally distinct sources (solid line) located at −20 deg and 20 deg under the assumption of additive (A) and multiplicative (B) frequency integration. The dotted lines show the responses to the sounds presented alone. (C,D) The population response to two simultaneous spectrally distinct sources when one source is five times more intense than the other. In each plot, the responses are normalized by subtracting away the minimum value and then dividing by the maximum value.</p> 2009-11-24 01:30:51 sources models additive multiplicative
