Figure 4From: A comparative analysis of swallowing accelerometry and sounds during saliva swallows Mean wavelet decomposition. Average and standard deviation of the wavelet energy composition of our signals. The left column in each group corresponds to the microphone signal, the middle corresponds to the superior-inferior accelerometer signal, and the right column corresponds to the anterior-posterior signal. The x-axis lists the approximate frequency range of each of the wavelet decomposition levels.Back to article page
