The phenomenon of hearing yourself in a microphone, also known as audio feedback or latency, can be frustrating and distracting, especially during live performances, recordings, or online meetings. It occurs when your voice is picked up by the microphone and then played back to you through your headphones or speakers, creating an echo or delay effect. In this article, we will delve into the causes of this issue and provide you with practical solutions to eliminate or minimize it.
Understanding the Causes of Audio Feedback
To address the problem of hearing yourself in a microphone, it’s essential to understand its underlying causes. Audio feedback can occur due to various factors, including the type of microphone, speaker placement, and audio settings. When sound from your speakers or headphones is picked up by the microphone, it creates a loop where the sound is continuously repeated back to you. This can happen in several scenarios, such as:
Microphone and Speaker Placement
The positioning of your microphone and speakers plays a significant role in audio feedback. If your microphone is too close to your speakers or if the speakers are facing the microphone, it can pick up the sound and create a feedback loop. Similarly, if you’re using a laptop or desktop with built-in speakers and a microphone, the proximity of these components can also cause audio feedback.
Audio Settings and Latency
Audio settings, such as gain levels, latency, and monitoring, can also contribute to hearing yourself in a microphone. High gain levels can make your microphone more sensitive, increasing the likelihood of picking up sound from your speakers or headphones. Latency, which refers to the delay between the time you speak and the time your voice is played back, can also cause audio feedback. If the latency is too high, you may hear your voice echoed back to you, creating a distracting and disorienting effect.
Hardware and Software Limitations
The quality and limitations of your hardware and software can also impact audio feedback. Low-quality microphones or speakers can be more prone to picking up background noise or sound from other sources, leading to audio feedback.

What causes the echo or feedback when I hear myself in a microphone?
The echo or feedback that occurs when you hear yourself in a microphone is typically caused by the microphone picking up the sound that is being played back through speakers or headphones. This can happen when the microphone is not properly positioned or when the volume of the speakers or headphones is too high. When the microphone picks up the sound, it sends it back to the audio system, which then plays it back again, creating a loop of sound that can be heard as an echo or feedback. This can be frustrating and distracting, especially when trying to record audio or communicate with others through a microphone.
To avoid this issue, it’s essential to position the microphone correctly and adjust the volume of the speakers or headphones to a comfortable level. You can also use noise-cancelling headphones or speakers with a built-in echo cancellation feature to reduce the likelihood of feedback. Additionally, using a microphone with a cardioid or supercardioid polar pattern can help to reject sound from the speakers or headphones and focus on the sound coming from your voice. By taking these steps, you can minimize the echo or feedback and ensure clear and high-quality audio.
How can I adjust my microphone settings to reduce echo or feedback?
Adjusting your microphone settings can help to reduce echo or feedback. One way to do this is to adjust the gain level of the microphone. If the gain is too high, the microphone may be picking up too much sound, including the sound from the speakers or headphones. By reducing the gain, you can help to minimize the amount of sound that is being picked up and reduce the likelihood of feedback. You can also adjust the EQ settings to boost or cut certain frequencies, which can help to reduce resonance and feedback. Additionally, some microphones have a built-in low-cut filter that can help to remove low-frequency rumble and hum.
To adjust your microphone settings, you can typically access the settings through your computer’s audio control panel or through the software that you are using to record or communicate with. Look for options such as “microphone gain” or “microphone level” and adjust the setting to a lower level. You can also experiment with different EQ settings to find the one that works best for your voice and recording environment. It’s also a good idea to monitor your audio in real-time to hear how the adjustments are affecting the sound. By making these adjustments, you can help to reduce echo or feedback and achieve high-quality audio.
What is the difference between a cardioid and supercardioid microphone polar pattern?
A cardioid microphone polar pattern is a type of polar pattern that is designed to pick up sound from the front and reject sound from the sides and rear. This type of polar pattern is commonly used in live sound and public speaking applications, as it helps to reduce feedback and minimize the pickup of ambient noise. A supercardioid microphone polar pattern, on the other hand, is a more directional polar pattern that is designed to pick up sound from a narrower angle than a cardioid polar pattern. This type of polar pattern is often used in applications where a high degree of isolation is required, such as in recording studios or film and television production.
The main difference between a cardioid and supercardioid microphone polar pattern is the degree of directionality. A supercardioid polar pattern is more directional than a cardioid polar pattern, which means it is better at rejecting sound from the sides and rear. However, a supercardioid polar pattern can also be more prone to feedback and resonance, especially if the microphone is not positioned correctly. In general, a cardioid polar pattern is a good all-purpose choice for many applications, while a supercardioid polar pattern is better suited for applications where a high degree of isolation is required. By choosing the right polar pattern for your needs, you can help to achieve high-quality audio and reduce the likelihood of feedback.
Can I use noise-cancelling headphones to reduce echo or feedback?
Yes, noise-cancelling headphones can be an effective way to reduce echo or feedback when using a microphone. Noise-cancelling headphones work by using one or more microphones to pick up ambient noise and then producing a “negative” sound wave to cancel it out. This can help to reduce the amount of sound that is being picked up by the microphone, which can in turn help to reduce echo or feedback. Additionally, noise-cancelling headphones can help to improve the overall sound quality by reducing the amount of ambient noise that is present in the environment.
When using noise-cancelling headphones with a microphone, it’s essential to position the microphone correctly and adjust the volume of the headphones to a comfortable level. You should also be aware that noise-cancelling headphones can sometimes introduce a slight delay or latency into the audio signal, which can affect the sound quality. However, for many applications, the benefits of using noise-cancelling headphones can outweigh the drawbacks. By using noise-cancelling headphones, you can help to reduce echo or feedback and achieve high-quality audio, even in noisy or reverberant environments.
How can I position my microphone to reduce echo or feedback?
Positioning your microphone correctly is essential to reducing echo or feedback. The ideal position for a microphone will depend on the type of microphone and the application, but in general, it’s best to position the microphone to pick up sound from the front and reject sound from the sides and rear. For a cardioid or supercardioid microphone, this typically means positioning the microphone so that it is pointing directly at the sound source, with the rear of the microphone facing away from the sound source. You should also try to position the microphone at a distance of at least 6-8 inches from the sound source to reduce the pickup of proximity effect and resonance.
When positioning your microphone, you should also be aware of the location of any speakers or headphones in the environment. Try to position the microphone so that it is not picking up sound directly from the speakers or headphones, as this can cause feedback. You can also use acoustic treatment such as absorbers or diffusers to reduce the amount of reverberation in the environment, which can help to reduce echo or feedback. By positioning your microphone correctly and using acoustic treatment, you can help to achieve high-quality audio and reduce the likelihood of feedback.
Can I use acoustic treatment to reduce echo or feedback in my recording environment?
Yes, acoustic treatment can be an effective way to reduce echo or feedback in your recording environment.
