Abstract: A front suspension device comprises a suspension arm, one end of which has a front-wheel support portion to support a front wheel of a vehicle and the other end of which is positioned on an inward side, in a vehicle width direction, of the front-wheel support portion and has a vehicle-body attachment portion to be attached to a vehicle-body member of the vehicle and a damper supported at a damper support portion which is provided at a portion of the suspension arm which is positioned in the vicinity of the front-wheel support portion at a lower portion thereof and connected to the vehicle-body member at an upper portion thereof. The damper support portion of the suspension arm has a breakage ease portion to cause breakage of the suspension arm.

Abstract: A signal-processing device includes a determination section that compares a frequency spectrum and a floor spectrum of an input audio signal to each other for each frequency bin and determines whether the input audio signal should be subjected to noise reduction processing or not for each of the frequency bins; and a noise reduction-processing section that subtracts a noise frequency spectrum from the frequency spectrum of the input audio signal for each of the frequency bins on the basis of the result determined by the determination section for each of the frequency bins.

Abstract: Provided are an imaging device, program, memory medium, and noise reduction method capable of appropriately reducing noise without causing degradation in a target sound such as voice. The imaging device of the present invention has: a video imaging unit for capturing video; a signal converter for converting a sound generated during video capture to a sound signal; subject determination units that predict or recognize a specific subject; a noise detector for detecting noise included in the sound generated during video capture; a noise reduction unit for reducing the noise signal from the sound signal; a voice detector for detecting non-noise signals in the sound signal; and a noise reduction performance change unit that lowers the noise signal reduction performance of the noise reduction unit when the subject determination units predict or recognize the specific subject.

Abstract: A signal processing device capable of reducing noise included in an audio signal, including: a conversion unit for converting an audio signal to a frequency domain signal; a subtraction unit for subtracting from a first frequency domain signal corresponding to a period in which the audio signal includes a predetermined type of noise, the frequency domain signal of estimated noise estimated to reduce the predetermined type of noise; a correction signal generation unit for generating based on a second frequency domain signal corresponding to a period in which the audio signal does not include the predetermined type of noise, a fourth frequency domain signal used to correct a third frequency domain signal obtained when the subtraction unit subtracts the frequency domain signal of the estimated noise from the first frequency domain signal; and an adding unit for adding the fourth frequency domain signal to the third frequency domain signal.
