It's called feedback. The microphone causes a loop, what is coming out if the amp is being asorbed by the mic, sent back to the amp and projected again. The loop causes a squeal.
If the snake gets nervous its tail begins to vibrate, making a buzzing noise. This noise serves as a warning to larger animals too big for the snake to eat.
The starter drive gear will be too close to the flywheel, causing a grinding noise when the starter is engaged.
Not that much... I mean, how much can it make?
A: Most op amp feature a 90 Db noise ratio rejection. For a 741c it varies from 70 to 90 Db ideally the bigger the number the better.
It's probably feedback. When you play a note on your guitar, it's picked up by the pickups and amplified by the amp. If you're too close to the amp, the pickups will pick up the amplified sound and it will get amplified again and again. Try moving farther away from the amp. If that doesn't help, make sure all the electrical connections in your guitar are connected properly (double check the output jack.)
no but it makes souffles flatten
a short or too much resistance thus heat
You have the gains set too high on the amp.
Monkey's make a kind of OO-OO-OOO-AAA-AAA-AAA noise. They can also make softer noises. Monkeys can also scream if they are scared. They make a kind of clicking or TCH-TCH noise sometimes, too.
Switch to distortion and move your guitar close to the amp to create feedback. Do't do this TOO often as it may hurt your amp and your ears. You can achieve it by playing pinch harmonics or Dimebag squeals. There are lessons EVERYWHERE for these! You wait until its not being played and just leaning against your bedroom wall unexpecting and then you jump in and yell at it.
They definitely don't rattle. However they don't make much sound at all. If you got close enough to hear one hiss you'd probably be too close for safety. They are poisonous but will only attack if provoked or surprised.
If you don't shut the door or make too much noise.
