In the era of my early school days, I remember that my teachers taught me about animals and their characteristics.
These were the days when I learnt that duck's quake cannot be echoed but as I grow up, I came to know that this is not a fact. Actually the duck's voice can echo and the claim is wrong.
The reality is that human ear is not capable of hearing it due to some external conditions. This is now proved from many experiments in which duck's sound is exposed into a room which is specially designed for sound reflection.
