When they have to make sounds under the water and above the water then they use their jawbones and nostrils, respectively. Hippos usually make a roaring sound when they want to show dominance and power over their partner or another animal which reaches kilometers away and can be easily compared with the loudness of a concert.
There are also those hippos who make such a low-frequency sound that cannot be even heard by humans. Not only this but a lot of times you will notice that a hippo makes a bubble blast as well as a fountain while making different sounds. Hippos also make sounds like grunts and laughs when they are in anger and trying to harm others whether they are humans near them or a group of other hippos.
How does a hippo make a sound?
Scientifically it is possible for sound waves to switch between different mediums at a time. But this factor does not bother the hippos even a bit to create noise under the water and above the water, simultaneously.
The mechanism is that half of their mouth is above and half is below the water which allows their jawbones and nostrils to pass sound waves through water vibration and air vibrations, respectively. Hippos sound usually measures between 10 Hz to 20 Hz which is bold, strong, and loud to be heard from kilometers away.

They usually honk loudly to make the group attentive and ready for a bad situation. Not only this but some male hippos also make a little whizzy honk to attract female hippos and announce the news later that they have done mating successfully.
They also play with their sound’s pace and frequency to make variations of honks during mating time.
