      @Ivan_The_Random_Guy ปีที่แล้ว +207

      As a musician ive personally experienced cases of that one particular frequency being louder than the rest because of this thing called resonant frequency, and it's interesting alright, but holy hell is it annoying to listen to in a musical setting, It just sounds so loud and so off, lmao.
      The fact that it also usually is the bass, too, you feel the rumble of the venue at that one particular note, and when the note changes the rumble fades to barely inaudible, Its a really weird and unavoidable experience during concerts.
      This made me realize something though, everything, legitimately everything, has a resonant frequency, may it be the speakers you play music to, the instrument you play, the venue of your concert, etc.

If a truck is making a 12Hz sine wave, we can't hear that with our ears. But if one of the walls in our house can resonate at that frequency, and we've got a picture hung up on that wall, then the sine wave coming from the truck's engine is going to move that wall, causing the picture to go "tap tap tap" against that wall 12 times a second--a sound we _can_ hear.

      Sympathetic resonance actually occurs inside pianos too. One string that has been struck by a hammer causes other strings which have not been struck by a hammer to vibrate in sympathy. The overall sound you hear is the vibration of multiple strings.
      If you are going to respond to a post and tell someone they don't know what they are talking about, you had better be damn sure you know what you are talking about. And you don't know what you are talking about.

      ​@@Mantium47you can do, but its often very subtle, the sympathetic resonance is often small in amplitude compared to the primary. So the strings will not be vibrating with as much energy.
      It varies so much from one instrument to another, fixed or floating bridges and trems (whammy bar), potentially even construction materials.
      Its also somewhat common to intentionally mute certain strings to prevent the vibrations creating sounds, like when tuning. Although some people like to tune around or work with them.
      But don't quote me, I am a terrible guitarist at best and a largely self taught physics fan!

    Early tv remotes worked off this principal. Pressing the button on the remote struck a piece of metal inside it that produced a specific pitch. The tv had a tuning fork in it that reacted to that pitch and would change the channel you were watching. Back then, there were only 3 tv channels, so remotes only had one button. Power and volume controls came later, when they switched to RF and IR remotes.

    • @Newnawn
      @Newnawn ปีที่แล้ว +1

      This is an important concept for bass players, where the low frequencies carry so much energy that playing without muting every other string makes the sound incredibly muddy, since the other strings start vibrating.
      I have no actual mathematical basis for this, but I'd guess that if high energy enough, one note can make a string of another note vibrate, as long as the note is a harmonic of the string.

      @@alexhaze9709 where to start 🤔
      We use radio waves to send signals all around us right, like cell phones, television, radio stations etc.
      Each radio station is a different radio wave/frequency for example. There are a bunch of different radio stations flying around in the air without interfering with each other.
      The reason for this is because each frequency is a different height. When a tone is started at a particular frequency, with an antenna and a transmitter (a cellular radio uses about 1520w for example), it will remain that same frequency as it travels.
      Echoes of it will ripple off into third and fifth harmonics that may effect other frequencies that fall into those harmonics/frequencies.

      Really? I'm abhorred at this. Obviously it doesn't only work when they match frequency. It clearly has to do much with the harmonic series and overtone decompositions / prime decompositions and the fourier. It's the same reason a snare drum vibrates at different various amplitudes over the entire frequency space! Not only on, say, 260Hz specifically. That is absolute nonsense! Can't believe I don't see more people in the comments pointing this out, and this guy is repping NASA and doesn't understand proper nuance. THIS WILL WORK AT 130HZ, even small rationals times 260 to various amplitudes, for crying out loud!!!
