Abstract

Over recent years, spatial acoustic signal processing using higher order microphone arrays in the spherical harmonics domain has been a popular research topic. This paper uses a recently introduced source feature called the relative harmonic coefficients to develop an acoustic signal enhancement approach in noisy environments. This proposed method enables to extract the clean spherical harmonic coefficients from noisy higher order microphone recordings. Hence, this technique can be used as a pre-processing tool for noise-free measurements required by many spatial audio applications. We finally present a simulation study analyzing the performance of this approach in far field noisy environments.
