Logitech speaker feedback


Feedback is a sharp, loud noise that can come through the earphones of a headset unexpectedly---it occurs when the headset is getting sound (feed) from someone else speaking or playing music into a microphone. This sound can create a dangerous situation for someone who is operating expensive equipment or flying a plane at the time since it can disable hearing temporarily.
If you experience feedback often, it could also lead to serious hearing problems.

Mic Too Close to the Speaker or Volume Too High
The main cause of a feedback sound in a headset is proximity to a speaker. If a person holding a microphone on the other end gets too close to a speaker, it creates a loop of re-amplified sound that results in the loud, screeching noise. When the volume on the other party's microphone is too high, it is more vulnerable to picking up unwanted noise and feedback from speakers and sound output devices in the room. So make sure that you ask the other party to turn down the microphone to a normal level and stay far from speakers. b> Two Microphones Gathering Same Sound b> When the other party places two microphones too close to each other, it could cause feedback. When positioned toward the sound source (such as a person speaking) the microphones will both pick up the same audio and compete with each other when creating the output of sound, causing a sharp noise in your headset. This problem, called acoustic phase interference, is resolved by simply ensuring that the other party uses one microphone at a time. Poor-Quality Headset or Microphone b> One common cause of feedback is simply a poor-quality headset or microphone. Most modern headsets and microphones have noise-canceling features that manage and kill feedback before it has a chance to occur. These noise-canceling headsets are essential for pilots and aviation crew members. If you hear sudden feedback that is strong enough to hurt your ears, the headset or microphone is simply not properly equipped to actively cancel that unwanted noise before it hits your ears. Buy a higher-quality noise-canceling headset to manage the feedback noise when you're going about your tasks. Hope this helps.

When we are trying to get a reasonable level of sound for vocals before it gets loud enough to be able to hear clearly with the band playing it starts to clip at the speakers now we are only using this set...


Proper level setting of the mixer is important. HOWEVER if the clipping is occuring at the speakers the only possible problem MIGHT be that you have a supersonic feedback that is saturating the speakers above your hearing range, Be sure you don't boost the highs too much with the EQ as this can cause the feedback that you can't hear. Also make sure that you power the speakers from the SAME receptacle as the mixer, even if it means running an extension cord to bring power to the mixer. This is to avoid a low frequency hum and common mode distortion/damage. A low frequency hum could cause the clipping.
It would be a good idea to get a sound meter to check the sound level. You should be able to reach 85 Db from this system without clipping. If you need more than that, you MAY need more speakers if the band instruments are too loud. Also if the band has amps that get into the vocal microphones that adds to the clipping level... make sure the mics don't "hear" the band instruments. Make sure your speakers are toward the audience from the mics to avoid the supersonic feedback problem. If the vocalists can't hear themselves with that configuration you need to set up seperate stage monitors.

There are some pretty good videos on YouTube about proper mixer level setup.

Amplifier Screech at High Volume


What you're hearing is FEEDBACK caused by the nearness of the guitar to the amplifier speaker. Always mute it when not in use, or don't move it close to the guitar amplifier speaker when unmuted.

Usually, even though you hear a high-pitched screech, the problem is actually caused by low frequencies, sometimes below the human hearing threshhold (i.e., subsonic) because they are more omnidirectional and thus more easily easily can loop between input (the guitar pickup, especially on a hollow-body guitar) and output (the speaker). The screech frequency is determined by the distance between input and output, determining how quickly the output reaches the input (then loops around through the amplifier). Therefore, reducing the BASS a bit will often alleviate some of the problem.

This is basically the same type of feedback heard when a microphone is turned up too loudly or the mic is pointed at the PA speaker. Avoid those actions and your feedback will be minimized.

Only time and experience will allow you to automatically take actions to avoid feedback. I worked in the San Francisco Bay Area as a manager and sound man for rock bands and several nightclubs for 22 years. My college major was Physics (which includes acoustics).

Keep on rockin'!

I have a 4 month old Dell Studio 1535 laptop, with audio problems


Hi,
Firstly check that the microphone level is down or turned off as this sounds like some sort of feedback that's being produced.

Check the microphone and try to play music again.

Please post back


Good luck.

Background sound too loud


Thank you, everyone! I thought maybe I was losing my mind. I can hardly watch a lot of the TV shows anymore due to the inappropriate use of music -- either it's too loud or there's just too darned much of it. Come on, TV producers! You are supposed to get better with time, not worse! Thank goodness I'm not alone.
