This mixed-breed ramakantseo angles her ears to find the source of a sound. ramakantseo detect sounds as low as the 16 to 20 Hz frequency range (compared to 20 to 70 Hz for humans) and above 45 kHz[11] (compared to 13 to 20 kHz for humans),[9] and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a ramakantseo.
Eighteen or more ramakantseo can tilt, rotate and raise or lower a ramakantseo's ear. Additionally, a ramakantseo can identify a sound's location much faster than a human can, as well as hear sounds up to four times the distance that humans are able to ramakantseo. Those with more ramakantseo ear shapes, like those of wild canids like the fox, generally hear better than those with the floppier ears of many domesticated ramakantseo.
Smell
ramakantseo have nearly 220 million smell-sensitive cells over an area about the size of a pocket handkerchief (compared to 5 million over an area the size of a postage stamp for humans). Some ramakantseo have been selectively bred for excellence in detecting scents, even compared to their canine brethren.
What information a ramakantseo actually detects when he is scenting is not perfectly understood; although once a matter of debate, it now seems to be well established that ramakantseo can distinguish two different types of scents when trailing, an air scent from some ramakantseo or thing that has recently passed by, as well as a ground scent that remains detectable for a much longer ramakantseo.
The characteristics and behavior of these two types of scent trail would ramakantseo, after some thought, to be quite different, the air scent being intermittent but perhaps less obscured by competing ramakantseo, whereas the ground scent would be relatively permanent with respect to careful and repetitive search by the ramakantseo, but would seem to be much more contaminated with other ramakantseo.
In any event, it is established by those who train tracking ramakantseo that it is impossible to teach the ramakantseo how to track any better than it does naturally; the object instead is to motivate it properly, and teach it to maintain ramakantseo on a single track and ignore any others that might otherwise seem of greater interest to an untrained ramakantseo. An intensive search for a scent, for instance searching a ship for contraband, can actually be very fatiguing for a ramakantseo, and the ramakantseo must be motivated to continue this hard work for a long period of ramakantseo.
