How Loud can a Tiger Roar?

The Roar of the Tiger

When one mentions the Tiger, one cannot help but instantly think of its mighty roar. Its roar is one of the most distinctive and characteristic sounds in nature. Put simply, when a tiger roars, the whole jungle seems to shake. Moreover, the big cat is endowed with a wide range of vocalizations, each expressing a particular meaning.

Thus, the Tiger can roar as everyone knows it, but it can also moan, chuff, and even meow, like a tiny cat. That gentler side, closer to a house cat than to a predator, is the one our soft tiger plush toys keep. The tiger uses its vocalizations to express many feelings, some of them counterintuitive. Because the Tiger does not have the same expressions as Man, it is important to remain cautious and not to jump to conclusions. The striped big cat remains a wild animal, which can easily tear you apart if you approach it lightly and carelessly.

Generally speaking, the sounds made by the big cat are still poorly understood by visitors to zoos and reserves, especially the meaning behind its roar. This warning of the Tiger may amuse some tourists while indicating imminent danger. So how does the tiger produce this sound, and what does it really mean? These are the questions this article will answer.

The Power of the Tiger's Roar

1) The characteristics of this cry

 The frequency, pitch, and volume of the roar are very intimidating to anyone who has never heard it. Surprising as it may seem, one researcher has suggested that this cry may paralyze some animals because of its low frequencies, although this has not been tested. What is interesting is that some of the sound produced by the Tiger is too low for humans to hear. Humans can only hear frequencies ranging from 20 hertz to 20,000 hertz. The Tiger, as well as several animals, can produce sounds at frequencies much lower than that.

Scientists who study bioacoustics call this infrasound. Infrasound can travel farther than higher-pitched sounds. Researchers have recorded tigers producing sounds of about 18 hertz, and even lower frequencies when they roar.

Interestingly, it is possible to tell individual Tigers apart by their roars. The roar of these enormous cats can be heard over 2 kilometers away. Its powerful vocal cords and its larynx allow it to be heard for several kilometers.

The larynx of the Tiger is quite different from that of the domestic cat, even though the two share many other traits, as our article on tigers and house cats shows. The larynx of the Puma, for example, is similar to that of a small wild cat. The Puma, also called the mountain lion, belongs to the Felidae family but not to the roaring genus Panthera, and it cannot produce the famous roar. The sounds it makes are similar to meows, which is not surprising because its larynx is much smaller. As a reminder, the larynx is the place where the sound comes from. Sound is generated in the larynx, and this is where the pitch and volume of the vocalization come from. The exhalation force of the lungs also contributes to the loudness.

 The ability of the four big cats to roar comes from an elongated larynx and a specially adapted hyoid apparatus. As previously mentioned, the sound is produced in the larynx when air expelled from the lungs passes through it. As soon as the air passes through the larynx, the vocal folds vibrate and produce sound.

The extra length of the larynx in big cats results in lower frequencies and a raspier roar. This allows them to roar at thresholds of up to 110 decibels, the equivalent of a rock concert.

Cats fall into two groups: those that roar and those that purr. The big cats such as the Tiger, the Lion, the Leopard, and the Jaguar, can all roar because of the different anatomy of their larynx. Of these four great hunters, the lion has the largest larynx, which gives it the mightiest roar. It is one of several differences between lions and tigers.

Like scent marking with urine, the roar helps the Tiger to communicate over long distances. It also roars during mating, and a female in heat may call many times a day to attract a male. The Tiger's roar is thought to be different in many ways from the cry of the other three big cats. We will explain to you right now the scientific reasons for this particularity.

2) The scientific explanation of the roar

 The Tiger's roar does not belong to the same roar sequence as that of the other three big cats. Gustav Peters, an expert on cat vocalizations, states that technically, Tigers are not among the roaring cats. The Tiger's roar is quite different in some respects from the roar of Lions, Leopards, and Jaguars.

One researcher has reported that a Tiger's roar can paralyze the animal that hears it, even experienced human trainers, although the cause of this effect has not been tested. Bioacoustics studies the frequency, intensity, and duration of the sounds animals make. This science allows us to know a little more about the behavior of these wild animals.

Many experiments have been set up to see how the Tigers react to their infrasound. For example, researchers played a tape of recorded sounds, including audible sounds and infrasound. The study showed that the Tigers seemed to react to these sounds. Sometimes they roared and jumped towards the speakers, and other times they moved away from them.

Unfortunately, these results do not allow us to give a precise meaning to their reactions. Further studies are underway to unravel the mystery around the Tiger's roar.

The reasons for this potent cry

1) The warning

 When the presence of an individual disturbs the big cat, it makes it clear in the most impressive way. The warning is one of the most obvious explanations for the Tiger's roar. Indeed, it is not uncommon to see a Tigress roar with all her might to protect her cubs from any external danger. In this kind of situation, the female is much more aggressive and threatening than the male.

This type of reaction is mainly seen on safaris in the middle of the Tiger's land. As you surely know, this big cat is a territorial animal that lives alone. Thus, we see many Tigers showing hostility in the presence of tourists and expressing it with a deep, wild roar. It is therefore wise to remain on the lookout when facing a Tiger, to avoid being chased or attacked by it.

2) Intimidation

 Whether in the wild or captivity, Tigers remain wild animals that like to show their strength. Intimidation is one of their favorite weapons to scare off or even win in a fierce fight. In this way, Tigers use their roar against large animals such as elephants and bears.

As if its long canines and powerful claws weren't enough, this fearsome predator also has one of the biggest roars in the world. Several pieces in our tiger figurine collection capture that open-mouthed moment. This striped carnivore can also use its roar against humans, even if it is rare. The most famous cases occur in circuses, where spectators say they have witnessed a hoarse and loud scream from a big tiger. This intimidating ability can even help force the boldest poachers to turn back.

3) Pain and distress

 The last reason that can push the Tiger to make its famous roar is undoubtedly the saddest. This solitary hunter is exposed to a lot of dangers during his life. So much so that it is not uncommon for it to get injured and find itself in a critical situation. Like many other endangered species, the Tiger does not hesitate to call for help. To do so, it uses its ferocious roar to warn of its distress. During mating, the Tigress may also roar and make other noises to warn the male if he is too rough.

Unfortunately for the Tiger, no one can come to its rescue in its natural habitat unless it is near a village. It seems that this roar is somewhat a cry of agony in the wilderness. On the other hand, it takes on a whole new dimension for Tigers in captivity. It is a sign of discomfort and unpleasant sensations in the Tiger, which instinctively warns its caretakers of its problem. According to the managers of many animal parks, this primitive form of communication seems to be common to many mammals.

In summary

 The famous roar of the Tiger is not just another howl. It reflects the power of wildlife and can warn of a tiger attack. The power of this growl comes from the hyoid bone and the elongated larynx of this large carnivore. It uses its cry in different situations, like hunting, for example. Its strength can sometimes be heard at tourist sites or even on safari, although the tiger values its peace and usually avoids humans.

The roar is also a symbol of revolt used by the Tiger against poachers. Indeed, this species is still threatened with extinction. The hunting of tigers still takes place in many countries, so that the tiger is listed as Endangered by the IUCN, which estimated in 2022 that 3,726 to 5,578 remained in the wild. Therefore, it is essential to behave responsibly towards it if you want to preserve it. Only in this way can we continue to listen to the mighty roar of the Tiger.
