20100005953 | VOLUME ADJUSTING APPARATUS AND VOLUME ADJUSTING METHOD - A volume adjusting apparatus includes a sound collecting unit configured to collect noise data of a surrounding environment, an analyzing unit configured to extract a feature value indicating a feature of the noise data collected by the sound collecting unit and a feature value indicating a feature of supplied musical tune data, and a control unit configured to generate volume adjustment information for adjusting playback volume of the musical tune data based on the feature value of the noise data and the feature value of the musical tune data and adjusts the playback volume of the musical tune data based on the volume adjustment information. | 01-14-2010 |
20100011024 | PLAYBACK APPARATUS AND DISPLAY METHOD - A playback apparatus is able to present song categories to the user that are suited to the current environmental noise. An audio pickup picks up noise data of the surrounding environment. A noise analyzer analyzes the noise data, and then extracts characteristic quantities expressing the characteristics of the noise data. A noise categorizer categorizes the noise data on the basis of the extracted noise data characteristic quantities. A content category database stores content data recorded onto a recording medium in association with categories based on characteristic quantities of the content data. A content category selector cross-references the noise data categorization result with the content category database, and on the basis thereof, selects a plurality of content data categories from among the categorized content data recorded onto the recording medium. A display unit then displays the selected plurality of content data categories. | 01-14-2010 |
20100246807 | Headphone Device - A headphone device includes: two output units for outputting playback audio which has been played back; a contact determination unit determining the occurrence of contact with respect to a telephone device; a first audio-collecting unit for collecting call voice generated from the telephone device; a second audio-collecting unit for collecting ambient external sound; and an output audio control unit performing control so that the call voice is outputted from one output unit of the two output units and the external sound is outputted from the other output unit when it is determined that contact has occurred by the contact determination unit. | 09-30-2010 |
20100295678 | MOBILE APPARATUS, METHOD OF CONTROLLING THE SAME, AND PROGRAM - Provided is a notice apparatus including: a plurality of notice signal generation units which generate notice signals; a reference signal output unit which outputs a reference signal used to determine an environmental situation; a reference signal detection unit which detects the reference signal output from the reference signal output unit and generates the detected reference signal as a detection signal; and a notice controller which controls one of the notice signal generation units to generate the notice signal based on the detection signal generated by the reference signal detection unit. | 11-25-2010 |
20110200210 | INFORMATION PROCESSING DEVICE AND METHOD AND PROGRAM - An information processing device includes: an output device configured to perform notification to a user by outputting ringing sound; a sound pickup device configured to pick up surrounding sound as ambient sound; an adaptive filtering process device configured to perform an adaptive filtering process using the picked-up ambient sound and the ringing sound output from the output device, to thereby extract, from the ambient sound, estimated environmental sound from which the ringing sound picked up by the sound pickup device has been removed; and a control device configured to control, on the basis of the feature quantity of a predetermined feature extracted from the estimated environmental sound, the adjustment of at least one of the sound volume and the sound quality of the ringing sound. | 08-18-2011 |
20120288105 | ACOUSTIC DEVICE AND METHOD OF DETECTING ABNORMAL SOUND - An earplug unit includes a signal processing unit. The earplug unit is inserted into an external auditory canal and then used. In the earplug unit, a speaker is arranged at an eardrum side, and a microphone is arranged at a side opposite to the eardrum side. The microphone collects a sound in which a user's head shape or auricle characteristic is reflected. An output signal of the microphone is amplification-processed by a volume adjusting unit and then supplied to the speaker. An amplified sound is output from the speaker. A frequency characteristic is smoothed in a band larger than at least an audible frequency band in a system from the microphone to the speaker. | 11-15-2012 |
