Microphone feedback is caused by the feeding the same signal back to the microphone, usually through a monitor speaker in a live concert situation. Because most microphones are not linear in frequency response, the feedback is usually being exaggerated and is heard as either a slow low sound or a really fast and spiky tone. For example a Shure SM58 has a spike around 1khz that usually feeds back really easily if you put your hand on top of the grille. If the feedback is really slow, it is usually below 1khz, if it is fast, it is usually above 1khz. You can try to remove feedback with better gain staging, better microphone choices and with an equalizer.

How does feedback work?
Most homeostatic control mechanisms are negative feedback mechanisms. In such systems, the net effect of the response to the stimulus is to shut off the original stimulus or reduce its intensity. or in simpler terms its just feedback that causes the stimulus to decline or end.
Which kind of feedback is used to reinforce correct behavior?
constructive feedback
In a feedback amplifier positive feedback produces an output that is?
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
When the body reacts to stop or work in the opposite direction of a stimulus is it known as negative feedback or positive feedback?
negative feedback
What is a feedback resistance?
Feedback resistance is as simple as it sounds. Feedback is someone other than our self looking at something we did and tell us their opinion. When we are resistant to their suggestions we are show feedback resistance.
What is voice feedback?
Voice feedback occurs when the microphone picks up sound from the speakers and 're-transmits' it - forming a feedback loop which is heard as a high-pitched 'squeal'
What is a sentence for earsplitting?
There was an earsplitting scream from the room next door.The feedback from the microphone was earsplitting.
What causes feedback in a sound reinforcement system?
Acoustic feedback occurs when the amplified sound from any loudspeaker re-enters the sound system through any open microphone and is amplified again and again. It is due to close placement of microphone to loudspeaker, open mic or reflective surfaces of the area etc.
What is the price range for a Shure Beta 58A?
A Shure Beta 58 A vocal microphone can cost anywhere between $159.00 to $179.00. Reviews for this microphone has been very good. It is reported to be very clear and feedback resistant.
Which microphone is best for a piano performance?
Ideally, you should have a microphone with no feedback -- you want a microphone that "senses" the movement of the strings rather than "hearing" the sound. You also want to avoid bleedthrough, and a clear sound is important. Every note on the keyboard should be the same volume. A mic made specially for the piano, such as the Hempinstill Piano Sensor, is a good choice.

What causes feedback hum?
Sound travels in waves like a pebble dropped in a pond. It radiates from the source. If you would drop multiple pebbles into the pond some wave peaks would increase other peaks and sometimes a valley would cancel out a peak by superposition. A feedback loop is formed when a speaker output is coupled back into a microphone whose output is being amplified by the speaker. Depending on the positions of the microphone and speakers, the gains involved, the directional patterns of the microphone and speakers and some environmental factors the the various frequencies essentially combine to form the hum and squeals you hear in a system with feedback. The original signals and amplified signals need to be close in time synchronization or you just get what sounds like echo.
How do you avoid loop back audio in recording?
Not quite sure what you are referring to. If you mean FEEDBACK....turn you speakers down to zero when recording with a microphone...just use headphones to monitor the signal.
What electrical devices are used to treat stuttering?
The Delayed Auditory Feedback (DAF) and Frequency-Shifting Auditory Feedback (FAF) are electronic devices that pick up a voice from a microphone, delay the sound for a fraction of a second, and feed the voice back. There is a list of them and where to get them on the web site for The Stuttering Foundation of America.
Why negative feedback is preferred in amplifier?
Because the feedback of an amplifier tends to reduce the gain of an amplifier and also, the bandwidth of feedback increases the gain of an amplifier, so in an high gain amplifier as to be stabilized. BY ENGINEER MUHAMMED OLALEYE OLUWATOSIN TELECOMMUNICATION STUDENT, RUFUS GIWA POLYTECHNIC, OWO
How do you stop feed back on your laptop speakers?
The likelihood is if you are using a laptop with an inbuilt microphone, this can be a problem on many new laptops as they actually come enabled with the microphone ready for input, that way, even with a minimal amount of sound, the microphone will pick it up and create feedback. Most laptops come with an fn key near the windows button on the keyboard, if you hold this and then look at your F1-F10 keys, one of them will most likely have a little microphone symbol, hold the fn key and press this F button and the microphone should switch of, resolving your problem, failing that, a pair of headphones on a mic work just as well. If you are playing online games and are using things like ventrillo, you can sometimes get feedback from talking into the mic and both mics picking up sound and relaying it through the speaker, a pair of headphones will resolve this completely.
