Abstract: An in-the-ear device such as a binaural microphone and an earphone is provided. An in-the-ear device 300 is used while being inserted into a human ear (external auditory canal), examples of which include the microphone and the earphone. This in-the-ear device 300 includes an in-the-ear device main body unit 310 substantially round column-shaped and a cylindrical inner side insertion unit 320 provided to protrude from an end surface of the in-the-ear device main stomach body unit 310 on an inner side. The in-the-ear device main body unit 310 is inserted closer to the inside than a first curve of the external auditory canal. As will be described later, an end surface of the in-the-ear device main body unit 310 on an outer side forms a surface substantially same as that of a cavum conchae while being worn. In addition, in the inner side insertion unit 320, the in-the-ear device main body unit 310 is provided to protrude closer to the inner side than the first curve of the external auditory canal in order to be along the external auditory canal.

Abstract: The present disclosure relates to a signal processing device, a signal processing method, and a program that make it possible to readily achieve personalization of head-related transfer functions in all bands. A synthesis unit generates a third head-related transfer function by synthesizing a characteristic of a first band extracted from a first head-related transfer function of a user and a characteristic of a second band other than the first band extracted from a second head-related transfer function measured in a second measurement environment different from a first measurement environment in which the first head-related transfer function is measured. The present disclosure may be applied to, for example, a mobile terminal such as a smartphone.

Abstract: Provided is a sound collecting device in which sound is favorably input to a sound collecting unit. The sound collecting device includes: an attachment portion that has a sound collecting unit attached and is adapted to be inserted into an external ear canal; a holding portion adapted to be inserted into the external ear canal and hold the attachment portion at a predetermined position in the external ear canal; and a wearing portion that is positioned on an opposite side of the attachment portion while interposing the holding portion and adapted to be at least partly engaged with an auricle, in which the attachment portion and the holding portion do not block the external ear canal and have acoustic transparency. Therefore, it is possible to provide the sound collecting device in which the sound is favorably input to the sound collecting unit because the attachment portion that has the sound collecting unit attached and is adapted to be inserted into the external ear canal, and the holding portion that holds the attachment portion at a predetermined position in the external ear canal are positioned in the ear in a state of not blocking the external ear canal.
