    Abstract: According to one embodiment, an acoustic control apparatus includes an acquisition unit, a detection unit, a correction unit, and an output unit. The acquisition unit acquires a first acoustic signal. The detection unit detects an information sound. When the detection unit detects the information sound, the correction unit corrects the first acoustic signal to a second acoustic signal by convoluting the first acoustic signal with a first function. The first function represents an acoustic transfer characteristic from a virtual position to a listening position. The virtual position is located along a first direction from the listening position. The output unit outputs the second acoustic signal.

    Abstract: An acoustic inspection apparatus includes a vibration sound source, a microphone group, and a processor. The vibration sound source emits a vibration sound to an inspection target object. The microphone group includes a first microphone arranged near the inspection target object and a second microphone arranged to have an interval with respect to the first microphone. The processor calculates a first impulse response between the first and second microphones, denoises a component corresponding to the vibration sound from the first impulse response, converts, into a frequency characteristic, a second impulse response obtained from the first impulse response, calculates acoustic energy between the first and second microphones based on the frequency characteristic, and determines an abnormal state of the inspection target object based on the acoustic energy.

    Abstract: A reproducing apparatus includes, a first sensor, processing circuitry, an audio reproducing device, and an image reproducing device. The first sensor detects a current location of a user. The processing circuitry acquires a destination, determines a direction of the destination based on the current location, generates a guidance sound image and a guidance image, and determines a first output timing which is an output timing of the guidance sound image and a second output timing which is an output timing of the guidance image. The audio reproducing device reproduces the guidance sound image at the first output timing to guide the user toward the destination. The image reproducing device reproduces the guidance image at the second output timing to guide the user toward the destination.
