A correction for converting 2 cm3 coupler responses to insertion responses for custom in-the-ear nondirectional hearing aids.
A correction for custom in-the-ear nondirectional hearing aids is obtained for converting a frequency response measured using a 2 cm3 coupler to an insertion response, approximating that measured using a manikin and ear simulator. The results are compared to those of a previous published study. The methods used for obtaining the responses make use of a signal analyzer with discrete Fourier transform capabilities.
