Killer whales Senses – Hearing

Killer whales have a well developed, sharp sense of hearing and it responds to frequencies in the range of 0.5 KHz to 125 KHz, where as an average humans range is 0.02-17KHz. Peek sensitivity is around 15 KHz.

Unlike the humans killer whales uses their lower jaw for sound reception effectively the frequencies above the range of 50 KHz. It also uses the tissue and the bone surrounding the ear for hearing sounds.

Killer whales use their ability to hear frequencies to locate and identify objects by projecting high frequency sound waves and listening for echoes. This is called ECHOLOCATION, very few other creatures has this ability such as the Bat. They project clicking sounds and then by receiving and interpreting the resulting echo, they locate and Identify objects. These clicks which killer whales produces lasts less than 1 millisecond. These Clicks include a wide range of frequencies, 25 KHz is being the peek and they also can vary the peak frequency to suit the event by varying the range between 10 KHz to 80 KHz.
