What’s Crackling in Your Speakers?

Crackling in your speakers can also be caused by amplifier problems, poor cable quality or condition, environmental factors like humidity or temperature, and software or firmware issues on your audio devices. These factors can disrupt the audio signal and lead to the annoying crackling noises you hear.

What Is the Sound of Crackling?

When you hear crackling from speakers and other audio devices, it disrupts your listening experience with sharp, intermittent, popping noises that distort the audio output. Some liken it to static or small explosions.

Often, crackling stems from loose or dirty connections in your audio setup, though it can also indicate failing equipment like amplifiers or damaged speaker cones needing replacement. It’s crucial to differentiate crackling from other issues such as distortion, which alters the original sound, and buzzing, a continuous low-frequency noise.

Buzzing is distinct from crackling’s sharp, irregular bursts of noise, making each issue recognizable in its own way.
