Abstract: Provided is an acoustic transducer which is used by being fitted into an ear of a listener, is formed in a compact and lightweight shape, and preferably prevents re-reflection of a sound wave. An acoustic transducer 100 is formed of a film-shaped material having an expanding and contracting action and includes a cylindrical acoustic transducing element 101. The cylindrical acoustic transducing element 101 also functions as a sound guide tube. The acoustic transducing element 101 prevents re-reflection of the sound wave reflected by an eardrum when the sound wave has been generated and prevents localization phenomenon and a feeling of pressure in auditory sense. Also, since the acoustic transducing element 101 is formed in a compact and lightweight shape, the acoustic transducing element 101 generates the sound wave for directly reaching the eardrum or collects the sound at a place near the eardrum without a feeling of foreign materials in a case where a person wears the acoustic transducing element 101 the an ear.

Abstract: The present technique relates to a sound processing apparatus, a sound processing method, and a program which are configured to obtain higher quality sound. In order to obtain an objective characteristic, the sound processing apparatus previously holds a characteristic of the sound processing apparatus, generates an inverse characteristic filter of the characteristic of the sound processing apparatus, and generates a correction filter from the obtained filter and a filter having the objective characteristic. The sound processing apparatus uses the generated correction filter to subject a sound signal to be reproduced to filter processing, and reproduces sound based on the obtained sound signal. Therefore, a characteristic to be originally obtained can be achieved. The present technique can be applied to the sound processing apparatus.
