Increased urbanization represents a formidable challenge for wildlife. Nevertheless, a few
species appear to thrive in the evolutionarily novel environment created by cities …

Publisher Summary Environmental noise can affect acoustic communication through limiting
the broadcast area, or active space, of a signal by decreasing signal-to-noise ratios at the …

On the occasion of the centenary of the discovery of the Lombard effect, we review the
literature on noise-dependent regulation of vocal amplitude in humans and other animals …

The acoustic environment has a major influence in shaping animal communication systems.
Humans, particularly in cities, profoundly alter the acoustic structure of their environment …

In cities with intense low-frequency traffic noise, birds have been observed to sing louder
and at a higher pitch. Several studies argue that higher song pitch is an adaptation to reduce …

The Lombard effect, an involuntary rise in call amplitude in response to masking ambient
noise, represents one of the most efficient mechanisms to optimize signal-to-noise ratio. The …

Any signal must get from a sender to a receiver if information is to be transmitted. In the case
of bird song, the acoustic properties of the habitat may hinder this being achieved. However …

Understanding the neural underpinnings of vocal–motor control in humans and other
animals remains a major challenge in neurobiology. The Lombard effect–a rise in call …

Research has shown that bird songs are modified in different ways to deal with urban noise
and promote signal transmission through noisy environments. Urban noise is composed of …

The Bengalese finch Lonchura striata var. domestica is a domesticated strain of a wild
species, the white‐rumped munia Lonchura striata of Southeast Asia. Bengalese finches …
