    The applicability of Gammatone Frequency Cepstral Coefficients (GFCCs) was studied by comparing its performance with Mel Frequency Cepstral Coefficients (MFCCs) in their combined noise environments. A multi-output artificial neural network model was developed to classify aircraft, road traffic, and combined noise, and to estimate the signal-to-noise (SNR) ratio when combined noise is detected. GFCC features were extracted using 64 Gammatone filters and 13 cepstral coefficients. Trained on 10 076 samples, the model achieved a classification accuracy of 99.94 % and an SNR estimation mean absolute error of 0.5432, outperforming MFCC-based models. These results demonstrate the effectiveness of GFCC in analyzing low-frequency dominant aircraft noise under combined noise conditions.
