The whales can communicate at farther distances (several hundred or kilometers away) than dolphins can, though.Josienita Borlongan is a full-time lead web systems engineer and a writer. Human ear perceives frequencies between 20 Hz (lowest pitch) to 20 kHz (highest pitch). The hearing range of most birds varies from 1000-4000 Hz; humans hear between 20-20,000 Hz (Hertz, a measure of frequency). "… frequencies from 8 kc/s to at least 200 kilocycles." Toothed whales are particularly adept at audible communication. This means that all three animals would be unable to appreciate the full range of Mariah Carey’s vocals, who reaches a top note of G7 in her song After canaries, pigeons, elephants and chimpanzees, humans are up next when it comes to the fifteen animals we compared – with a hearing range between 20Hz and 20,000Hz. These small openings are what they would usually use for hearing when they are not underwater.


However, their hearing ranges start at 1,000Hz, meaning that even if they could speak the same language as turtles, neither would be able to hear each other!The animal with the largest hearing range in the world is the porpoise, and the dolphin relative is able to hear between 75Hz and 150,000Hz.Let us do the hard work for you. extends only to about 20 kHz. Noise pollution from boats, sonar, and more can cause dolphins to lose their hearing over time. For example, exposure to chemical pollution in the water can reduce the sensitivity that dolphins have to touch. Each object or animal underwater sends off different echoes, which the dolphins can differentiate. Each individual has its own unique whistle that serves to distinguish who and where the whistle is coming from. The dolphin hearing range is also broader than that of many species, which allows them to hear specific sound sand frequencies that humans cannot. Dolphins have sharper hearing senses and a broader range than humans do. Dolphins are able to listen to a broader range of frequencies than humans are. The goldfish doesn’t fare much better, with a range of between 100Hz and 2,000Hz, with frogs only being able to hear between 100Hz and 3,000Hz. Los Angeles: University of California, 1963: 43.

"… frequency range between 20,000 … The higher end of the range was more varying listing upper frequencies of 120,000 (two sources), 150,000, 164,000 and 200,000 Hz. Dolphins use small ear openings on both sides of their heads to listen to or hear sounds. Unfortunately for us, that means we’re able to hear and understand (to a degree) all of PSY’s Our favourite household friends, cats and dogs, have similar hearing ranges that are over twice as wide as humans, but the cat’s favourite living toy – the mouse – has hearing twice as good as that!It’s sea creatures that seem to fare best when it comes to hearing, however, with beluga whales and dolphins able to hear over 120,000Hz.
