Simple Explanation

To make something quieter or weaker in strength—usually reducing volume or signal level.

Concise Technical Definition

To reduce the amplitude or strength of a signal, typically measured in decibels (dB).

Layman-Friendly Analogy

Like turning down the water pressure from a hose—you're not stopping the flow, just softening it.

Industry Usage Summary

Common in signal chains, mixers, preamps, and room treatments, attenuation reduces unwanted gain or overly strong signals to prevent distortion or balance levels. It’s also used in EQ and filtering.

Engineering Shortcut

Attenuate = reduce level (in dB); opposite of amplify.

Full Technical Explanation

In audio and electronics, to attenuate means to reduce the amplitude of a signal, often to prevent overload, distortion, or mismatched gain between components. Attenuation can be applied using passive resistive elements (pads), adjustable controls (attenuators), or digital processing. The amount of attenuation is typically expressed in decibels (dB), where a reduction of -3 dB halves the power. It plays a key role in dynamic range management, room acoustics, signal routing, and system calibration.
