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.

Bought new dynex dx-740 earclip headset with microphone. earpiece works but computer not picking up microphone.


Have you installed the software for your headphone? Your computer might not pick up your device because it doesn't recognize the device.

How to make my headset work on my acer


You should be able to plug the headset into any available USB port on your ACER and then follow the prompts to download the drivers from the web. If that doesn't work then you can go to the Dynex site for support. This is the website to use:

Bose QC3 makes a high pitch noise when i press it against my ear


The design of these headphones includes a microphone on the outside and on the inside of each earcup. The outside microphone detects outside noise. The inside microphone monitors what you are hearing and when it detects that the outside noise is present inside, the active noise-canceling circuits remove that noise. This happens fast enough that you perceive a siginficant reduction in the outside noise getting to your ears.

The airspace inside the earcup is a tuned chamber defined by the foam in the ear cushion. This is important because with the inside microphone in close proximity, but at a 90-degree angle to the speaker, the circuit must be designed to eliminate the normal feedback that occurs. When you press the earcup close to your ear, you are changing the size and shape of the air chamber inside of the earcup thus directing more of the speaker sound toward the microphone than the design can compensate for causing audio feedback to occur. You are hearing that feedback. Removing your hand from the earcup should restore the shape of the air chamber allowing the circuits to return to normal operation.

If the feedback occurs too easily when you are NOT pressing on the earcup, then the foam may have weakened/deteriorated and it may be time to replace the ear cushion.

On my QC-3 headphones, I can cause the feedback squeal in both earcups, with the left earcup being more sensitive to the shape change than the right.
