The evolution of the Lombard effect: 100 years of psychoacoustic research (2011, background): “Indeed, Japanese quail (Coturnix coturnix japonica), king penguins (Aptenodytes patagonicus) and chaffinches (Fringilla coelebs) produce more redundant signals when communicating in noisy environments (Potash, 1972b; Lengagne et al., 1999; Brumm & Slater, 2006b).”
Strategies of song adaptation to urban noise in the house finch: syllable pitch plasticity or differential syllable use? (2009, background): “…signal transmission, such as increase in sound amplitude (Brumm, 2004), number of same song types within a bout before changing to another song type (Brumm & Slater, 2006), and increased minimum song frequency (Slabbekoorn & Peet, 2003; Fernández-Juricic et al., 2005; Wood & Yezerinac, 2006).”
Multimodal communication of wolf spiders on different substrates: evidence for behavioural plasticity (2011, background): “In addition, animals may compensate for environmental noise by adjusting signalling behaviour to different frequencies (Wiley 1991; Slabbekoorn & Peet 2003) or by changing call/bout duration (Brumm & Slater 2006).”
Which birds adjust the frequency of vocalizations in urban noise (2010, background): “For example, some urban birds increase signal redundancy (Brumm & Slater 2006), vocalize louder (Brumm 2004), use more pure tones (Dubois & Martens 1984) or avoid times of more intense noise (Bergen & Abs 1997; Fuller et al. 2007).”
