Abstract: It is an object of the present invention to provide a sound image localization apparatus which can localize a sound image with ease correctly for many listeners.Herein disclosed is a sound image localization apparatus, in which a directional band information storage unit 11 is adapted to store therein directional bands in advance calculated for respective directions, a control filter computing unit 12 is adapted to read a directional band corresponding to a target position information from a directional band information storage unit 11 upon receiving target position information, calculate a control filter coefficient in such a manner that the maximum value of a sensation level for which masking is taken into consideration is matched with the directional band thus read, output the control filter coefficient to a sound image localization processing unit 13. Upon receiving the control filter coefficient from the control filter computing unit 12, the sound image localization processing unit 13 is adapted to convolve the control filter coefficient thus received to an inputted sound source signal, carry out sound image localization processing on the sound source signal, and output a sound signal whose sound image has been localized as a sound image localization signal to a sound reproducing device, not shown, such as, for example, headphones, a speaker, and/or the like.

Abstract: A hearing aid that prevents the user from missing new speech when listening again to recorded speech. This hearing aid comprises a speech input section, a speech buffer, first and second direction adjustment sections, a hearing aid processor, and a speech output section. The speech input section inputs a speech signal. The speech buffer holds a speech signal inputted to the speech input section. The first and second direction adjustment sections subject a first speech signal inputted to the speech input section and/or a second speech signal held in the speech buffer to speech processing such that the first speech signal and the second speech signal are each perceived independently. The hearing aid processor subjects signals outputted from the first and second direction adjustment sections to hearing aid processing. The speech output section outputs a speech signal that has undergone hearing aid processing at the hearing aid processor.
