Duck quacks do echo.
It is a scientific myth that a duck's quack does not echo. Research has shown that a duck's quack does echo, but it is hard to hear because it is difficult to distinguish the quack from the echo.
There are several reasons why it is difficult to hear the echo:
- Echoes are produced after loud noises. Ducks quack very softly, so the reflected sound is difficult to hear.
- A reflecting surface is needed to hear an echo. Ducks tend not to live near reflecting surfaces such as cliff faces or buildings. An echo could be heard more readily if the duck quacked whilst flying past such as surface.

∙ 16y agoThe answer to this question lies not in the "animal" part but in the "noise" part. Noise is sound. Sound is mechanical energy. Sound can be reflected off surfaces with varying amounts of attenuation (loss) depending on the nature of that surface. Certainly sounds come in a variety of amplitudes (volumes) from loud to soft to almost silent. Given the basics of sound, any noise can echo if conditions support that. And just because someone might not hear the noise, that doesn't mean that a tiny signal can't echo. Many animals have better hearing than people do. And contemporary electronics can pick up stuff that no one could possibly hear. Which animal noise does not echo? Any noise made by an animal has a probability of creating and echo if there is something near enough to reflect even the smallest part of the incident sound.
