    • Disclosed herein, among other things, are methods and apparatus for binaural enhancement of tone language for hearing assistance devices. One aspect of the present subject matter includes a method for enhancing pitch in a hearing assistance system having a first and second hearing assistance device. A signal is received using a microphone of the first hearing assistance device. Pitch detection is performed on the signal to obtain a pitch value. The pitch value is wirelessly transmitted from the first hearing assistance device to the second hearing assistance device. In various embodiments, the pitch value of the first hearing assistance device is combined with a pitch value of the second hearing assistance device. The gain is adjusted based on the combined pitch value, in various embodiments.

    • A quantitative calculation method for oil (gas) saturation of fractured reservoir during petroleum exploitation is provided. The method comprises: obtaining the fracture porosity and calculating resistivity index at different depth of fractured reservoir with known full diameter core data and imaging logging data; establishing the percolation network model of matrix and fracture combination with known pore structure feature; calibrating the numerical simulation results obtained from percolation network model based on the data of core experiment and sealed coring analysis results, then obtaining the relationship between the resistivity index (I) and water saturation (Sw) at different fracture porosity; calculating the oil (gas) saturation of fractured reservoir through selecting an interpolation function. The oil (gas) saturation calculated with said method is 0.67, however 0.49 with common method in some fractured reservoir. The accuracy is improved by more than 0.18 in the studied fractured reservoir.
