Mel-Frequency Cepstral Coefficient-Enabled Analysis of Doppler Effect on Road Traffic Noise from Nairobi City
This study investigated the Doppler effect on road traffic noise levels in an urban setting by deploying Mel-Frequency Cepstral Coefficient (MFCC) to characterize acoustic signatures across vehicle mix classes. Using a dataset of audio recordings from Nairobi city’s road network sampled from 42 sites, the study adjuste...
