* Noisy depends on the context: What's considered noisy depends on where you are, what you're used to, and what kind of sound you're measuring.
* Measuring noise: We can measure sound in decibels (dB), but some animals produce different types of sounds (e.g., clicks, whistles, roars) that are difficult to compare.
* Noise pollution varies: Animal sounds can be loud, but they don't always cause "noise pollution" like humans do.
That said, here are some animals often considered extremely loud:
Land Animals:
* African Elephant: Their trumpets and rumbles can reach 117 dB, comparable to a jet engine.
* Howler Monkey: These primates have the loudest call of any mammal, reaching 140 dB.
* Blue Whale: Although technically in the water, they produce sounds reaching 188 dB.
* Lion: Their roars are powerful and can be heard for miles, reaching around 114 dB.
* Gorilla: These primates can produce loud roars and growls, reaching over 100 dB.
Water Animals:
* Blue Whale: As mentioned above, their calls are the loudest of any animal, reaching 188 dB.
* Sperm Whale: They produce powerful clicks and whistles that can reach 160 dB.
* Dolphin: Their clicks and whistles can be very loud, reaching over 120 dB.
Other:
* Cicadas: Some cicada species have calls reaching 120 dB.
* Flies: While small, some flies can create a surprisingly loud buzzing sound, reaching 90 dB.
It's important to remember that even though these animals produce loud sounds, they use them for communication, navigation, defense, and other important purposes.
