Description
Digital signal processing technique using normalized spectrogram correlations to quantify acoustic signal degradation by comparing two-dimensional spectrograms between reference and experimental distances. Uses 256-point FFT with Hamming window to generate spectrograms for correlation analysis.
Typical Equipment
- Canary 1.2 software
Output Measurements
- normalized correlation coefficients
- signal similarity measures
