Usage Note
Interférence is used in both physics (the interference of waves) and figuratively for unwanted meddling in affairs. The verb interférer means 'to interfere' and is largely limited to technical or formal registers. In everyday speech, se mêler de is more natural for personal interference.
Examples
"Des interférences brouillent le signal radio."
Natural Translation
