This paper proposed a novel hearing loss detection method. Our method first used seven Hu moment invariants to extract features. Afterwards, we used support vector machine to act as the classifier. The 10x5-fold cross validation shows our method yielded an overall accuracy of 77.47± 1.17%. The sensitivities of healthy control, left-sided hearing loss, and right-sided hearing loss are 77.60± 5.72%, 77.60± 4.30%, and 77.20± 5.98%, respectively. In all, our method is effective in hearing loss identification.

This paper gives a new iterative method to solve the non-linear equation. We prove that this method has the asymptotic convergent order 1 3 +. When the iterative times exceed 2, only one evaluation of the function and one of its first derivative is required by each iteration of the method.Therefore the new method is better than Newton's method.
