Have you ever been to a concert only to be greeted with a high-pitched squeal that made you cringe? Well, folks, that’s audio feedback, the unwanted guest at every live event! In this post, we’ll dive into the world of audio feedback and teach you how to tame this sonic beast. Armed with this knowledge, you’ll be able to make your live sound experience a harmonious one – without any ear-piercing interruptions.<\/p>\n\n\n\n
So, buckle up and get ready to discover the ins and outs of audio feedback<\/strong>, from understanding its types to mastering the art of prevention. We’ll also explore the magical realm of microphone placement, directional microphones, and speaker positions, as well as the powerful tools that can help you control feedback in a recording studio environment.<\/p>\n\n\n\n What is audio feedback? <\/strong>Audio feedback is the high-pitched squeal or howling sound that occurs when a microphone picks up sound from a speaker and amplifies it back into the system, creating a continuous loop. This phenomenon can be disruptive and unpleasant, making it crucial to understand and manage during live sound events and in recording studios.<\/p>\n\n\n\n Audio feedback, also known as acoustic feedback or simply feedback, is a positive feedback situation that occurs when an acoustic path exists between an audio input (e.g., a microphone or guitar pickup) and an audio output (e.g., a loudspeaker).<\/p>\n\n\n\n In this scenario, a signal received by the microphone is amplified and passed out of the loudspeaker. If the output sound is picked up by the input again, it creates a loop, and the sound is continuously amplified<\/strong>, resulting in the characteristic high-pitched squeal or howl associated with feedback.<\/p>\n\n\n\n To manage and control audio feedback, sound technicians may use sound mixing boards or equalizers as part of the public address (PA) system. These tools help balance the loop and cut off the amplification, preventing feedback from occurring or becoming a problem during performances.<\/p>\n\n\n\n Audio feedback is caused by a positive feedback loop<\/strong> that occurs when an acoustic path exists between an audio input, such as a microphone or guitar pickup, and an audio output, like a loudspeaker.<\/p>\n\n\n\n When sound from the audio output is picked up by the audio input, it is amplified and sent back to the output. This continuous amplification of the sound creates a feedback loop, resulting in the characteristic high-pitched squeal or howl associated with audio feedback.<\/p>\n\n\n\n Factors that contribute to audio feedback include the proximity of the microphone to the loudspeaker, the volume and gain levels, the room’s acoustics, and the frequency response of the audio equipment.<\/p>\n\n\n\nHow does audio feedback work?<\/h2>\n\n\n\n
