Boy it’s hard to believe these little guys turn into the big feared predators they become. I recently stumbled across a territorial video of two tigers fighting (none were injured or hurt) but their roar when angry makes it harder to believe.
That is the same sound you hear.
Think like this: As these are 'natural produced' sounds and sound is physics (these are waves that travel through air and come from an organic body) the body (its size and volume) that produces the sound are very important for the outcome.
So what does this mean?
If you have a small body with a small volume (volume is NOT loudness here it is weight f.e.) and you want to produce a deep sound – you do not have the equipment to do so.
And you can test this yourselves at home, if you start to pitch your voices down. If something is bigger – has more mass – it has more bass(it is deeper).
In sound-design we (humans) are doing this for years. We take some branches. Break them in front of a microphone, pitch them down – and you think a tree falls over.
It is a sound-designer 'rule' – if you want to create something big, take something small of the same material and pitch it down. As this is all physics. So more mass an object has so more bass/deeper frequencies you do have.
So that little tiny tiger-baby – does exact the same sounds you heard in your video of the fighting tigers. The only difference is – that it has not the mass/the body of a full grown tiger.
This is why you think: Cute. As your brain (and not only your brain – animals run on the same) computes if something sounds light, high-pitched it is small. Small like a baby, a cub.
If you hear a rooooar – nobody thinks mice – you think of something big.And sometimes are surprised how a small dog or animal can be very deep and loud (that is technics how they do this and even learned behaviour - dog-packs f.e. create their own pack-language - that does not sound to us the same, if you have big and small dogs together - but they all bark in the same way if they grew up together). I once did a test with a dog-trainer, who works with small dog who grew up with a very big one - and applied the formula (see below) and played it to her - and it fooled even her (who is 24/7 around her dog) that she thought that is the big dog and not the small one. So if you have at home two different species of dogs - their vocalization is exact the same - it just does not sound like it because they have different bodies. What is the result of imitation. They imitate each other not only in sound even in physical features and that goes even cross species, but that is not the topic right now.
So actually you hear the same roar, the same sounds – only from a very tiny body.
Fun fact only if you think that is interesting: In 2014/2015 – we took because of a research domestic cat sounds (I do field-/nature recordings with a focus on animal communication and sound in nature)– how we have to pitch and change the sound – if a domestic cat would be of the size of a tiger.
The outcome was, that if you take a Meow (from a cat) – and give it weight/mass/and the body it turns into the iconic tiger: Ahoom.
And then we did it the other way around – and the tiger's: Ahoom – turned into a domestic cat's Meow.
So cats and tigers do the same call. It only sounds so different (to write them down we even use totally different letters), because they target different frequencies (high and low), based on their body (mass, size, volume).
You can even try that out at home. Take a cat-sound – pitch it down, but keep the speed and you will get already some decent results or do it the other way around with a tiger call.
If that is not 100% that is because you do not have the best source material/or sound equipment, but you will hear similarities already without doing some advanced math and use MP3s.
So if you hear a tiger calling: Ahoom - ahoom.
That is actually the same Meow-Meow you are familiar with from your domestic cat.^^
Edit: (friendly) Lol. As I saw Swjosdotschka's sig. Neverending quest for more wolves.^^ (I remember you from some month ago). Well done in execution. Love it! I hereby support you on your quest, because of your passion for wolves and how you show this. In case you read this. Did not want just to click the like-button. I do love such stuff. Very well done.
