Equal-loudness contour-based loudness compensation method and device, and audio processing system

ActiveCN102378085ALow costLoudness compensationMultiple-port networksTransducer circuitsEqual-loudness contourWeight coefficient
The invention provides an equal-loudness contour-based loudness compensation method, which comprises the following steps of: regulating a volume of an input signal, measuring sound pressure levels corresponding to all available volume values, and in each sound pressure level, filtering an input signal by using a preset frequency filter, and multiplying by a weighting coefficient of the preset frequency filter to obtain a signal; and superposing the input signal in each sound pressure level in a plurality of sound pressure levels corresponding to all the available volume values and the signal obtained through filtering and weighting. The method overcomes the defect that when the conventional audio signal is small in volume, the loudness of partial frequency band is too low, and ears of a human body cannot feel the loudness, so that the heard sound is dry and tedious; by the method, the loudness of input signals of partial frequency band is compensated, the sound is loud and full and meets the requirement of people on acoustic comfort; moreover, a sound level meter and the filter and simple computation are only required to realize the loudness compensation of the audio signal, so that the structure is simple and the cost is low.

Adjustable Breast Positioning System for Women's Garment

ActiveUS20100210179A1Improve visual presentationIncrease volumeBrassieresHandkerchiefsVisual presentationEngineering
An improvement for an adjustable breast positioning system for a breast received within a breast cup of a woman's garment comprising a platform situated within a lower region of the breast cup; a shaping member at least partially overlaying the platform wherein the platform and shaping member are open to the top portion of the breast cup; and a connector having one end coupled to the platform and another end connected to an anchor moveably mounted to the garment for adjusting the platform for reducing the available volume for the breast within the breast cup and for concomitantly pushing the shaping member upward and inward for displacing the breast upward, forward, and inward toward the center of the wearer's chest while simultaneously increasing the volume of the breast outside the top portion of the breast cup for providing an improved visual presentation of the breast. Disclosed is a breast positioning system and related methods of use for women's garments comprising at least one breast cup, a platform situated within the breast cup and means for applying a force to the platform while the platform is below the breast of the wearer. The breast positioning system further features a flexible shaping member and at least one apparatus configured to push the flexible shaping member down into at least one of the breast cups.
