Elephants use a wide range of vocalizations for social interaction and communication, from loud roars to low-frequency rumbles. Their vocalizations range from snorts and barks to grunts and trumpets to screams and even imitations of human speech.
An elephant family relies on these calls for crucial indicators to ensure everyone’s safety. Joyce Poole, an elephant scientist, National Geographic Explorer, and Petter Granli, the other co-director of ElephantVoices, have collected thousands of recordings of elephant calls.
In an elephant auditory database, they have separated these into distinct “call kinds” (such as rumbles and trumpets) and using behavioral context, call tone, and measurement, they have interpreted the numerous nuanced differences between each type.
Wide Range Of Vocalization
Elephants rub trunks together as a kind of greeting and may engage in friendly rivalry when doing so. Parents and older elephants can be harsh disciplinarians by slapping, kicking, or pushing young elephants with their trunks.
When meeting new people or getting excited, people of all ages and both sexes tend to touch one another in intimate places including the mouth, temporal glands, and genitalia. This facilitates the detection of chemical cues by individuals.
Mothers and their calves rely heavily on touch as a means of bonding and communicating. Mother elephants will touch their young with their trunks or feet if they are walking side by side, or their tails if the calf is behind them.
In order to rest, a calf will press up against its mother’s front legs, and it will touch its mother’s breast or leg when it is ready to nurse. Elephants have a wide range of vocalizations, including some at very low frequencies that we can’t pick up.

The article delves into the many sounds made by elephants. The names, significances, and production mechanisms of many noises will also be explained to you. Then you’ll know where to go to hear an elephant choir in the wild!
What Sounds Do Elephants Make?
Can you describe the sound an elephant makes? These massive African animals can be heard making a wide range of sounds, from rumbling to trumpeting.
When air is forced through the trunk, a trumpeting sound is produced. It’s a behavior elephants engage in when they’re extremely excited. The primary method of interaction is grumbling. Elephants can roar, bark, grunt, snort, and even imitate human speech.
Elephants make a variety of noises, most of which originate in the larynx but may also be altered by the trunk. The trumpet cry, made by blowing through the tree’s trunk, is probably the most well-known.
- Trumpeting is a vocal expression of joy, anger, or sadness. Elephants can roar or shriek when fighting, and wounded elephants can bellow for help.
- Growls, squeaks, and snorts are the most often documented sounds made by Asian elephants. Simple growls are employed for communicating over small distances.
- Growls reverberate in the trunk and become rumbles at low levels of excitement, while roars are used for long-distance communication. Infrasonic growls can be produced in a variety of situations.
- There are two types of squeaks: chirpings and trumpets. Chirping, which consists of many short squeaks, is an indication of tension and conflict. Trumpets are prolonged squeaks made at high volume to express intense excitement.
- The volume and frequency of snorts both increase during moderate or intense arousal. In the latter situation, elephants use booming sounds made by bouncing the trunk’s tip as a form of threat show.
1. Trumpeting
The elephant orchestra produces a wild sound unlike any other. When several elephants begin trumpeting at the same time, the result is a cacophony of sound that reverberates for miles. To human ears, the trumpeting of an elephant is the most distinctive sound associated with these animals. When prompted, they give off this signal.
If they are in a really lively and joyful mood, they might do it, too. An elephant will also use its trumpet when it is confused, furious, or taken aback. One can liken the sound of a trumpet to the shouting of a crowd. A person might produce this sound while excited or upset, but it could have a variety of meanings.
Elephants use trumpeting, which is similar to shouting, to alert others and draw attention to themselves. The noise is typically short and loud, lasting only a few seconds. When an elephant spots a lion in the area, it will blow its horn briefly to warn the herd.
Sometimes, when one of the elephants is particularly irritated, it may blow its trumpet for a considerable amount of time to let everyone know that it is on its way through and won’t be stopping.
It’s the sound elephants make when they’re really joyful and lively, much like the noise people make when we’re excited. The elephants will playfully gallop around, trumpeting and flailing their trunks. It reminds me of a schoolyard, complete with excited kids running and yelling.
The larynx, or voice box, as it is more commonly called, is where most animals produce vocalizations. In the same way, elephants can. The elephant’s trunk is what actually makes the trumpeting noise.
2. Grunts And Snorts
Researchers have suggested that elephants can be heard making snorting and grunting noises. They are produced in the trunk and resemble a trumpet’s tone.
3. Mimicking Sounds
Individual elephants have the ability to mimic the actions of other elephants. That’s why when one elephant creates a certain kind of low-frequency rumble, another elephant may imitate it and make a rumble of its own in response.
4. Squeaks And Chirps
However, unlike their Asian counterparts, African elephants are unable to create sweet chirping and squeaking sounds. No one knows for sure, but it’s likely because the larynx allows for such a wide variety of vocalizations.
5. Rumbling
The trumpeting of an elephant is the most well-known noise made by the animal, its high pitch being audible from great distances. But most people who claim to hear elephants are actually just ramblers. Sounds with such a low frequency can travel great distances. This serves as their primary means of communication.

Rumbling is a lovely resonant sound, similar to a cat purring but deeper and more sonorous, so turn up the bass on your speakers or headphones to really appreciate it. The larynx is responsible for producing rumbling. To communicate with one another, elephants utilize this sound.
6. Roaring
Scaring away a lion or getting a safari vehicle to move typically only requires a loud, high-pitched trumpet. This noise is often accompanied by rumbling, which could be a distress signal. But when they don’t get their way, elephants have been known to roar.
A roaring sound is a deep, resonant rumbling. A trumpet fanfare is frequently played alongside it. Elephants will only make this noise in extreme circumstances, such as when they need to scare away a competing herd or protect themselves from a predator.
Infrasonic Calls
Elephants are capable of making infrasonic noises, with frequencies lower than 20 Hz. Especially for long-distance communication, Asian and African elephants rely on infrasonic cries.
Asian elephants’ calls last for about ten to fifteen seconds and have a frequency of 14 to 24 hertz, with a sound pressure of 85 to 90 decibels.
African elephants can communicate over long distances using cries with a frequency range of 15–35 Hz and a sound pressure level of up to 117 dB. This allows them to cover large areas, with a probable maximum range of roughly 10 km (6 mi).
The Peculiarity Of Vocal Tract
Elephants have the largest known larynxes of any mammal. It has long vocal folds that are linked to the epiglottis towards its base. The vocal folds of an elephant are much longer, much thicker, and have a much bigger cross-sectional area than those of a human being.
And unlike human vocal folds, which are positioned in the back of the mouth, these are upfront and slanted at an angle of 45 degrees. The elephant larynx is demonstrated to generate complicated vibrational phenomena in a number of experiments.
These events may occur in real life when the vocal folds and vocal tract work together to either increase or decrease the fundamental frequency. Because of its peculiar architecture, the larynx vibrates in a variety of ways, including alternating A-P (anterior-posterior) and P-A traveling waves.
You can recognize it by the unusual opening and closure of the glottis. Phonation in the larynx begins at a tracheal pressure of around 6 kPa, and laryngeal tissue begins to vibrate at 15 kPa.
The laryngeal tissues undergo self-maintained oscillations, and the processes for producing vocalizations at particular frequencies are comparable to those used by humans and other animals.
These propagating wave patterns can be set in motion by two biomechanical factors: a decrease in fundamental frequency and an increase in longitudinal tension in the vocal folds.
