Major progress has been made in understanding how animals hear and may be impacted by noise. While overall amplitude is clearly relevant in terms of how sounds in the ocean may affect animals, other aspects of sound, such as frequency, directionality, duration, novelty, and other factors can be as or even more important (e.g., Ellison et al., 2012).
