Abstract: An audio communication device includes: a sound position determiner that determines sound localization positions for N audio signals in a virtual space having first and second walls; N sound localizers each performing sound localization processing to localize sound in the sound localization position determined by the sound position determiner, and outputting localized sound signals; an adder that sums the N localized sound signals, and outputs a summed localized sound signal. Each sound localizer performs the processing using: a first head-related transfer function (HRTF) assuming that a sound wave emitted from the sound localization position of the sound localizer determined by the sound position determiner directly reaches each ear of a hearer virtually present at the hearer position; and a second HRTF assuming that the sound wave emitted from the sound localization position reaches each ear of the hearer after being reflected by closer one of the first and second walls.

Abstract: An acoustic signal processing device includes: a front signal processor which generates first L and R signals by performing signal processing on a first signal which is a front channel signal; a first adder which generates a fourth signal which is a left channel signal by adding the first L signal and a second signal which is a left channel signal; and a second adder which generates a fifth signal which is a right channel signal by adding the first R signal and a third signal which is a right channel signal. The front signal processor generates the first L and R signals by signal processing in which the first signal is distributed and placed at predetermined positions when the first signal is a dialog signal, and distributed and placed at positions different from the predetermined positions when the first signal is not a dialog signal.

Abstract: An audio processing apparatus includes a preprocessor which extracts a voice-band signal from a first electric signal, and outputs a first output signal containing the voice-band signal; a first controller which generates a first amplification coefficient for multiplying with the first output signal to compress a dynamic range of an intensity of the first output signal, and generates a first modified amplification coefficient by smoothing the first amplification coefficient with a first time constant; and a first multiplier which multiplies the first modified amplification coefficient and the first output signal. The first time constant is a first rise time constant when the intensity increases, and is a first decay time constant when the intensity decreases. The first rise time constant is not less than a temporal resolution of hearing of a hearing-impaired person, and is less than a duration time of sound which induces recruitment in the hearing-impaired person.
