Abstract: Disclosed is a transfer film for three-dimensional molding in which at least a surface protection layer and a primer layer are layered in this order on a transfer base material, wherein the surface protection layer is formed by a cured product of an ionizing-radiation-curable resin composition including: polycarbonate (meth)acrylate and/or caprolactone-based urethane (meth)acrylate; and an isocyanate compound.

Abstract: The present invention provides a sheet for three-dimensional molding, said sheet having excellent scratch resistance and moldability and effectively suppressing interference fringes. Provided is a sheet for three-dimensional molding, said sheet having at least a surface protection layer laminated upon a substrate, wherein the surface protection layer is formed from a cured product of a resin composition that includes an ionizing radiation-curable resin and inorganic particles having an average particle size of 100 nm or more, and the content of the inorganic particles in the surface protection layer is 40 mass % or more.

Abstract: An audio signal processing device includes: a microphone configured to collect noise; an analyzing unit configured to analyze an audio signal collected by the microphone to detect the level and frequency property of the collected audio signal; and a signal processing unit configured to subject an audio signal to be reproduced to signal processing based on the analysis results of the analyzing unit.

Abstract: An electricity-to-sound converter reproduces a sound according to a first audio signal. A sound collector outputs a second audio signal. A first frequency band limit filter filters the second audio signal. A sound leakage evaluating block evaluates a leakage of a sound reproduced by the electricity-to-sound converter on the basis of the first audio signal and the filtered second audio signal. A multiplier multiples the first audio signal by a coefficient approximating a transmission characteristic between the electricity-to-sound converter and the sound collector when the sound reproduced by the electricity-to-sound converter leaks outside a housing to be picked up by the sound collector. A second frequency band limit filter filters the multiplied first audio signal and supplies the filtered first audio signal to the sound leakage evaluating block. The first frequency band limit filter and the second frequency band limit filter have passing bands of 1 kHz to 3 kHz.

Abstract: Disclosed herein is a sound outputting apparatus, including: an electro-acoustic conversion section disposed in a housing and configured to acoustically reproduce a first sound signal; a sound collection section configured to collect sound outside said housing and output a second sound signal; a surrounding noise evaluation section configured to evaluate surrounding noise outside said housing based on the second electric signal; and a control section configured to perform predetermined control based on a result of the evaluation of said surrounding noise evaluation section.
