Perceptibility of Inharmonicity in the Acoustic Guitar
Abstract:Audibility of inharmonicity in acoustic guitar tones was studied through formal listening experiments separately for steel- and nylon-stringed guitars. Test tones were resynthesized from real recordings through high-resolution parametric modeling of acoustic guitar sounds, which allows accurate control of the inharmonicity of the partials. Inharmonicity was detected fairly easily by the subjects for the lowest strings especially for the steel-stringed guitar. For the nylon-stringed guitar, inharmonicity was also detected as long as the plucking transient was left out of the sound, but detection was much harder for the full sound with transient. Detection thresholds were obtained for two pitches at the low range of the nylon-stringed guitar. Mean thresholds were close to, though above, typical amounts of inharmonicity in the guitar. Implications to digital sound synthesis are discussed.
