20090262949 | MULTI-CHANNEL ACOUSTIC SIGNAL PROCESSING DEVICE - Provided is a multi-channel acoustic signal processing device by which loads of arithmetic operations are reduced. The multi-channel acoustic signal processing device ( | 10-22-2009 |
20090326934 | AUDIO DECODING DEVICE, AUDIO DECODING METHOD, PROGRAM, AND INTEGRATED CIRCUIT - An audio decoding device of the present invention includes: a decoding unit decoding a stream to a spectrum coefficient, and outputting stream information when a frame included in the stream cannot be decoded; an orthogonal transformation unit transforming the spectrum coefficient to a time signal; a correction unit generating a correction time signal based on an output waveform within a reference section that is in a section that overlaps between an error frame section to which the stream information is outputted and an adjacent frame section and that is a section in the middle of the adjacent frame section, when the decoding unit outputs the stream information: and an output unit generating the output waveform by synthesizing the correction time signal and the time signal. | 12-31-2009 |
20100061466 | DIGITAL BROADCAST TRANSMITTING APPARATUS, DIGITAL BROADCAST RECEIVING APPARATUS, AND DIGITAL BROADCAST TRANSMITTING/RECEIVING SYSTEM - For MPEG-2 AAC, MPEG-Surround or (AAC+SBR), whether a received bitstream is of AAC or MPS can not be determined till the details of the received bitstream is analyzed up to the end. Therefore, if the output delay of an audio signal is large, the output of a video signal cannot appropriately be delayed under control, not allowing A/V synchronization. | 03-11-2010 |
20100254554 | HEARING AID, HEARING-AID APPARATUS, HEARING-AID METHOD AND INTEGRATED CIRCUIT THEREOF - A hearing aid ( | 10-07-2010 |
20110142272 | HEARING ASSISTANCE SUITABILITY DETERMINING DEVICE, HEARING ASSISTANCE ADJUSTMENT SYSTEM, AND HEARING ASSISTANCE SUITABILITY DETERMINING METHOD - A hearing assistance suitability determining device ( | 06-16-2011 |
20110280424 | SYSTEM, METHOD, PROGRAM, AND INTEGRATED CIRCUIT FOR HEARING AID - To provide a hearing aid system ( | 11-17-2011 |
20120250915 | HEARING AID DEVICE - A hearing aid is used for a low tone frequency band, a hearing aid is used for a high tone frequency band, and a controller that compares sound pressure of the high tone frequency band split by a frequency band analyzer of the hearing aid used for the high tone frequency band with sound pressure of the high tone frequency band split by a frequency band analyzer of the hearing aid used for the low tone frequency band. If the sound pressure of the high tone frequency band of the hearing aid used for the low tone frequency band is higher by at least a specific amount than the sound pressure of the high tone frequency band of the hearing aid used for the high tone frequency band, the sound pressure of the high tone frequency band of the hearing aid used for the high tone frequency band is raised. | 10-04-2012 |
20130156240 | HEARING ASSISTANCE SUITABILITY DETERMINING DEVICE AND HEARING ASSISTANCE SUITABILITY DETERMINING METHOD - A hearing assistance suitability determining device, that determines suitability including whether a subject can clearly hear speech using dichotic hearing assistance, includes: a subject hearing ability information input unit; a hearing ability type determining unit that determines at least one hearing ability type that corresponds to the hearing ability information, based on hearing ability information frequency characteristics; a suitability determining unit that determines suitability for dichotic hearing assistance based on the at least one hearing ability type determined by the hearing ability type determining unit; and suitability presenting unit that presents the suitability determined by the suitability determining unit. The suitability determining unit determines, by referring to a correspondence relationship, suitability based on clarity improvement for speech sound corresponding to the determined hearing ability type, the correspondence relationship indicating, for each hearing ability type, degree of perceived speech clarity improvement by the dichotic hearing assistance. | 06-20-2013 |
20130202138 | HEARING AID, HEARING AID FITTING MANAGEMENT SYSTEM, SERVER DEVICE, AND COMPUTER DEVICE - A hearing aid fitting management system comprises a fitting device, a server, and a client device that are connectable to each other in a network. The server stores hearing ability data received from the client device as a hearing ability certificate, produces a prescription number corresponding to the hearing ability certificate, and sends the prescription number to the client device. The fitting device sends the server the prescription number that has been inputted. The server sends the fitting device the hearing ability certificate corresponding to the prescription number received from the fitting device. The fitting device sends the hearing ability certificate to a hearing aid, and limits the settings in the fitting of the hearing aid to within the range of the hearing ability data. | 08-08-2013 |
