SOUND VOLUME SENSING TYPE SOUND QUALITY CORRECTING DEVICE

摘要

PURPOSE:To allow a listener to listen to a sound with sound volume corresponding to a preset sound quality before automatically by applying the sound quality setting at a certain sound volume and storing the sound quality characteristic with respect to the sound volume at the point of time of setting. CONSTITUTION:A sound volume state detection means 4 detects the sound volume state of a sound volume variable means 1, and a sound quality characteristic selection means 5 selects a filter coefficient corresponding to the sound quality characteristic set by a sound quality variable means 2 from a 1st storage means 9. A 2nd storage means 6 stores the sound volume state data from a sound volume state detection means 4 and a sound quality characteristic data selected by the sound quality characteristic selection means 5. A sound quality characteristic readout means 7 reads the sound quality characteristic data from the 2nd storage means 6 in response to the sound quality state data from the sound state detection means 4 and a sound quality characteristic variable means 8 varies the sound quality in response to the sound quality characteristic data. Thus, the aural sense correction to the sound quality set before is attained automatically at the sound volume by having only to set the sound quality to a preferred quality depending on the sound volume.
