1. the process of making something weaker, thinner, or less in force, intensity, or value
2. the reduction in strength of a signal, beam, or wave as it passes through a medium
Usage: technical; physics

Examples

• The attenuations in the radio signal made it difficult to hear clearly.
• Scientists measured the attenuations of light passing through different materials.
• The vaccine showed significant attenuations in viral strength.
• Fiber optic cables minimize signal attenuations over long distances.
• The researcher documented various attenuations in the experimental data.
• Sound attenuations increased with distance from the source.
