Although hippos are semi-aquatic animals, they love to pass most of the time semi-submerged in the water. Hippos usually spend their life both in water and on land. The unique lifestyle of the hippopotamus has made people curious to know what noise does a hippo make underwater, as it is said that 80% of their communication happens under the water surface.

However, hippos are able to communicate both under the water and above the water surface concurrently. A Hippo uses nostrils to produce noises above water and jaw bones to resonate the noises under the water surface. And this is obviously one of the unique features that these African mammals have.

You will be amazed to know that most people don’t know that hippos are able to make loud sounds. ‘Are hippos loud? A common question asked by many animal lovers. The simple answer to this question is yes, hippos can make loud sounds that can reach up to 115 decibels.

Hippos roar and honk to assert their dominance. Hippopotami make loud sounds that reach the neighboring parts and this loud sound can be heard even from a mile away and the sound level can be compared as equivalent to a Rock concert.

However, there are hippos that produce noises at very low frequencies known as infrasound. Even humans cannot recognize this sound as the level is below the range of human hearing.

The hippos produce noises that range from 10 to 20 Hz while making a fountain. You can also find the ‘bubble blasts’ produced by a hippopotamus which is similar to that of a grey whale. Hippos also create chain chorusing to facilitate distant communication.

Hippopotamuses usually stay in groups. There might be 20 to 100 individuals in a group led by a male hippopotamus. Besides, the group will have female members along with some non-breeding young male hippos.

The male hippopotamus grunts, roars and groans to claim its periphery. When a male hippo honks to announce its leadership of the group, other hippopotami of the similar group rely on their leader for getting alarms about any kinds of upcoming dangers.

Hippos also produce noises like a laugh but a laughing hippopotamus can be dangerous. Hippopotami are aggressive African animals. They can be harmful to humans and their lugubrious faces can be deceiving.

How does a Hippo make sound

We know that sound waves are unable to switch mediums. While making sounds the mouth of a Hippo remains submerged in water. Above the water surface, the produced sounds go through the nostrils to the air while the sounds also resonate through the jawbones of the hippo underwater.

This sound can easily be heard above the water surface but the hippos underwater hear these sounds through the vibrations of the sound waves.

A hippo has a fat layer near its neck that helps to produce the sound vibrations underwater. That way, hippopotamuses are communicative both above the water surface and under the water surface simultaneously.

Hippo Yawn

Hippopotamuses love to chat and communicate with other hippos. They widely open their mouths producing ‘yawns‘ and at this time they seem to be very happy but those sounds are actually a threat sign. The male hippo usually honks to inform other hippopotamuses in the group about any threat. And honking is a common hippo communication method. The male hippos also produce these honking sounds after mating with a female one and through these wheezy honking sounds they try to announce the occurrence of mating.

However, hippos’ mating call sounds made by the male hippos are the auditory signal to attract female hippopotami. Though mating calls can be categorized into two-the mechanical calls and vocalizations, the hippopotamuses use their unique vocalization technique while producing mating calls.
