It appears that\u00a0Kemp\u2019s ridleys\u2019 best hearing aligns with the low-frequency band that hosts a significant amount of sounds, presumably from industrial operations in the ocean like oil and gas drilling and vessel traffic, <a href=\"https:\/\/www.eurekalert.org\/news-releases\/1114627\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:according to Muirhead;elm:context_link;itc:0;sec:content-canvas\" class=\"link \">according to Muirhead<\/a>.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">\u201cThis is significant because we\u2019ve known that their movements and distribution overlap with industrial and boat noise sources both in space and time\u2014and we\u2019ve now confirmed that the turtles are capable of detecting these sounds,\u201d Muirhead says. \u201cHowever, detecting sound does not automatically mean it causes harm or disturbance. Whether noise \u2018bothers\u2019 turtles depends on several factors, including sound level, duration, distance from the source, and the behavioral or ecological context in which the exposure occurs.\u201d<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">Now that we know what these turtles can hear, future research can investigate just how human sounds impact them and what that means for <a href=\"https:\/\/www.popsci.com\/diy\/protect-sea-turtles-beach\/\" rel=\"nofollow noopener\" target=\"_blank\" data-ylk=\"slk:conservation efforts;elm:context_link;itc:0;sec:content-canvas\" class=\"link \">conservation efforts<\/a>.<\/p>\n<p class=\"mb-4 text-lg md:leading-8 break-words\">More broadly, Muirhead explains that, \u201cunderstanding how animals perceive their environment is essential for effective conservation.Hearing is only one piece of the puzzle.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"For the world\u2019s smallest sea turtles, life in the ocean is getting pretty noisy.
