Simple Explanation

Unwanted noise caused when a cable or component picks up sound from being moved or rubbed.

Concise Technical Definition

Noise or signal interference generated by mechanical vibrations or physical contact affecting sensitive electronic components, especially cables or tubes.

Layman-Friendly Analogy

Like hearing a thump in your headphones just from brushing the cord with your hand.

Industry Usage Summary

Common in poorly shielded or low-quality headphone cables, vacuum tubes, and phono cartridges. Considered a flaw in audio gear; low-microphonic designs are preferred for clarity and reliability.

Engineering Shortcut

Noise caused by physical movement of cables or components.

Full Technical Explanation

Microphonics refers to the unwanted noise or signal artifacts generated when mechanical vibrations or friction affect sensitive components, such as cables, vacuum tubes, or phono cartridges. These vibrations are converted into electrical signals, introducing audible interference—often perceived as clicks, thumps, or rubbing sounds. High microphonics is especially problematic in headphones, in-ear monitors, and analog systems, where physical contact with cables or chassis can degrade audio quality. Quality shielding, damping materials, and robust component design help reduce microphonic effects. In high-fidelity or professional audio equipment, low microphonics is considered essential for performance.
