Figure 7From: Efficient voice activity detection algorithm using long-term spectral flatness measure Histogram of the logarithmic LSFM measure for jet cockpit, HF channel, F-16 cockpit, and factory floor noises (SNR = 0 dB). Upper left: jet cockpit noise, upper right: HF channel noise, lower left: F-16 cockpit noise, and lower right: factory floor noise.Back to article page
