Abstract:
A sound quality display apparatus, a sound quality display method, and a computer readable medium on which a sound quality display program is recorded are provided to display an exact position of a noise source by overlaying image data of a background of a sound source with sound quality data. A sound quality display apparatus(100) includes a sound sensing unit(110), a background photographing unit(120), a sound source signal generating unit(130), a sound quality data generating unit(140), and a display unit(150). The sound sensing unit senses sound of a sound source. The background photographing unit photographs a background of the sound source. The sound source signal generating unit generates a sound source signal by sequentially performing Fourier transform, beam-forming, and inverse Fourier transform on a sound signal sensed by the sound sensing unit. The sound quality data generating unit generates sound quality data as loudness by sequentially performing one-third octave band analysis, loudness weight application, and total loudness calculation on the sound source signal. The display unit generates sound quality image data by overlaying the background image photographed by the background photographing unit with the sound quality data.
