This is the principle of piano tuning. You play different intervals (2 keys) and tune the strings so they will beat at a certain number per second. Once you have set up the tuning of the central part of the piano you then proceed to tune each note so that there are absolutely no beatings between the three strings per key (high- to mid range) or the two strings per key (low range). Finally you extend the tuning to the highest and lowest range of the piano by octaves (c-c, d-d etc.); some piano tuners add a very slight detuning here ("stretch" tuning) and others don´t; also, each piano is individual so some sound better with stretch tuning and others better without it. To tune a piano is to be 100% aware of the beatings between the notes.
I have learned that; 1. Without anything on it, every tuning fork has the same frequency, which results in equal and comparable sound waves; and 2. Two beats have distinct frequencies. Additionally, we can hear that the sound on the left frequency is somewhat unpleasant to our ears due to destructive interference, which quickly cancels out the sound.
fbeat = |f1 - f2|, right? Then if I were to introduce a third frequncy:f3, would there be a second beat frequency: fb2, fb2 = |fb - f3| ? And so on fb3 = |fb2 - f4| ...?
I don't believe thats exactly how it works but the outcome is similar to what you expect. The beat frequency is not a sound wave but rather a wave of changing amplitude, which is the result of the two soundwaves going in and out of phase with each other and therefore either amplifying or canceling each other. Therefore the "beatwave" wont form another beat with a new sound wave. So what you WOULD hear is a combination of 3 beats consisting of fb1 = |f1-f2| , fb2 = |f2-f3| and fb3 = |f3-f1|. I tried this with a short script playing me 3 sinus waves at 440, 439 and 442 Hz. It was quite bizarre to hear because the result was some sort of polyrhythm of changing loudness with a big wobble of 1 second and 2 smaller ones of 1/2 and 1/3 seconds. Not sure if thats what you meant initially but trying it out and hearing the result was quite interesting anyways so thanks for asking :D
This happens due to the phenomenon of superposition... Here two sound waves are generated Initially there was no frequency difference due to which the amplitudeof the two waves super imposed giving us a constant amplitude equals a1+a2 and there was no formation of beats. But as the frequency of one of the wave varied their super imposition gave us a variable amplitude resulting a wowowo wo sound that we call as beat

Most string instruments are the same! Albeit a little less complicated lol
This proves that Physics is present in music too . Just try to observe !
It is cayding some disturbance in my heart ..
My time has come.
You should go fast
Frequency rules the Universe.
Agreed

Like attracts like.
Amazing..
How long does the tone last with one hit?
Good
thank you
What is the item called that you attached to the tuning fork?
Tuning Fork Singing Box
👍Nyx..
I'm wearing 🎧
😮 wow OMG do u want a medal
What's really going on ✅🤣
Samj ni a rhi
But why?

You mean how right?😂
@@debojitdeori4837 Thank you for explaining it better. This topic is not easy to visualize
