    Abstract: Provided is an information processing apparatus that carries out a process of deriving a head related transfer function. The information processing apparatus includes a detection unit that detects a position of a head of a user, a storage unit that stores a head related transfer function of the user, a determination unit that determines a position of a sound source for measuring the head related transfer function of the user based on the position of the head detected by the detection unit and information stored in the storage unit, a control unit that controls the sound source to output measurement signal sound from the position determined by the determination unit, and a calculation unit that calculates the head related transfer function of the user based on collected sound data obtained by collecting, at the position of the head, the measurement signal sound output from the sound source.

    Abstract: Provided is a sound output device worn on an ear of a listener and used, and having listening characteristics of an ambient sound in a wearing state. A sound output device 100 includes a sound generating portion 110 that generates a sound, a sound guiding portion 120 that takes in the sound generated in the sound generating portion 110 from one end 121, and a holding portion 130 that holds the sound guiding portion 120 in the vicinity of the other end 122. The holding portion 130 is engaged with an intertragic notch, and supports the sound guiding portion 120 such that a sound output hole of the other end 122 of the sound guiding portion 120 to face a depth side of an ear canal. Even in a state where the listener wears the sound output device 100, the sound output device 100 does not block an ear cavity of the listener, and the listener can listen to the ambient sound.

    Abstract: Disclosed is a signal processing apparatus including a surrounding sound signal acquisition unit, a NC (Noise Canceling) signal generation part, a cooped-up feeling elimination signal generation part, and an addition part. The surrounding sound signal acquisition unit is configured to collect a surrounding sound to generate a surrounding sound signal. The NC signal generation part is configured to generate a noise canceling signal from the surrounding sound signal. The cooped-up feeling elimination signal generation part is configured to generate a cooped-up feeling elimination signal from the surrounding sound signal. The addition part is configured to add together the generated noise canceling signal and the cooped-up feeling elimination signal at a prescribed ratio.
