Respuesta Lombard Frente a Ruidos Antropogénicos Cuasiperiódicos: Una propuesta teórica-matemática.
Abstract
Noise is a form of pollution resulting from the undeniable increase in industrialization worldwide. Anthropogenic noise can have negative effects on the survival of a species, as it can mask acoustic signals relevant to foraging, mate searching and distribution. In response to this, the Lombard effect acts as a compensatory mechanism, and refers to an increase in the amplitude of acoustic signals in response to an increase in background noise level. In this study, a theoretical-mathematical approach is proposed to illustrate a simple classification based on three general types of Lombard response. Finally, by means of numerical simulations, we graphically analyze the effects of Lombard responses in a mathematical model of population persistence in a critical and quasi-periodic noise environment.
