Signal-to-Noise Ratio (SNR)

Definition

Signal-to-Noise Ratio (SNR) is the ratio between the useful AE signal and background noise.

Explanation

A higher SNR indicates better signal quality and more reliable detection of acoustic emission events.

Key Notes

• Critical for data quality
• Influenced by environment and equipment
• Improved by amplification and filtering
