Summary: This study aims to quantitatively analyze the relationship between the complexity of audio signals and the neurocognitive attributes, by examining the changes in pitch, loudness, and timbre of sound. EEG experiments were conducted to observe how the brain responds to variations in these basic components of sound. The results indicate a correlation between linear parameters and nonlinear features in the acoustic domain, while also revealing new information about the cognition of sound features in the human brain.

Summary: This paper investigates the relationships between audio features and semantic timbre categories, and uses statistical models for prediction. The results reveal significant effects of extended technique, pitch register, and instrument family on perceived exertion, emotional valence, and semantic timbre. Additionally, non-linear methods outperform linear models in predicting semantic ratings from audio features, suggesting the advantage of non-linear approaches in timbre semantic predictions. The study also demonstrates that overlapping features can differentiate related semantic categories through individual patterns of audio feature relationships.

Summary: The relative position of spectral envelopes along the frequency axis serves as a cue for musical instrument size and family identity, and is influenced by fundamental frequency and dynamic level. Low-dimensional cepstral audio descriptors can accurately discriminate between instrument classes, but the envelope shape becomes less indicative when dealing with different dynamic levels or F0-registers.

Summary: This study conducted two investigations to explore the influence of harmonic loudness on timbre. The first investigation examined piano timbre preference using non-processed melodies and adjustments made with an equalizer. The results showed that participants preferred the audio material produced by reducing the loudness of the 7th and 9th harmonics and enhancing the loudness of the 8th harmonic. The second investigation examined different degrees of adjustments, with the 15 dB change being the most preferred. These findings provide a new approach to improving sound timbre in sound engineering and artificial intelligence music production.

Summary: Infants show high perception ability for pitch and timbre, even exceeding that of adults without musical training. This suggests that infants have high coding fidelity for audio features.

Summary: Information in speech and music is conveyed through changes in fundamental frequency (f0), which is perceived as relative pitch. Relative pitch judgments are influenced by timbral differences and can be based on constituent frequencies or f0 estimates. This study examined the effects of timbre on relative pitch judgments and found that timbral differences influenced the accuracy and bias of pitch judgments. However, this effect was similar for harmonic and inharmonic sounds, and was observed even when judgments were based on f0 representations.

Summary: Cultural backgrounds have a greater impact on affect perception than musical backgrounds, with musicians being more adept at distinguishing between perceived and felt measures. Acoustic features play a key role in different emotional perceptions, with similarities in features contributing to the perceived affect ratings across different instruments.

Summary: The study revealed that participants have good and fairly linear sensitivity to vibrato depth regardless of vibrato type, but there are some poorly understood findings between the physical signal and perception of TV. This suggests that more research is needed in TV perception.

Summary: Tonotopy, an orderly mapping of frequency, is observed throughout the auditory system. Studies have shown evidence for pitch tuning in certain cortical regions that partially overlap with traditional tonotopic maps of spectral content.

Summary: This study investigated the impact of sound on bimodal perception of motion, finding that complex sound stimuli significantly improve performance, biological motion provides the best performance, and constant-velocity motion provides the worst performance.

Summary: This study proposes an improved music vocoder algorithm based on the conjunction of harmonic and time sampling (HTS). The algorithm extracts pitch and harmonics of the music signal, and matches them with the existing CI channels, resulting in better pitch ranking scores and higher melody recognition rates compared to the classical continuous interleaved sampling (CIS) algorithm. The HTS algorithm also enhances the timbre perception of CI vocoder music.

Summary: Marketing heavily relies on auditory information, such as background music, jingles, and sound logos. This study examines the influence of the instrument used in a brand's sound logo on consumers' perceptions of the brand's personality. The findings show that the instrument choice impacts perceived sophistication and ruggedness, and the effect is comparable to the influence of visual logo design on brand personality perceptions.

Summary: The study examined the effects of timbral instructions on pitch and timbre production, revealing a significant impact on pitch but not on timbre. Participants preferred neutral instructions and tuning accuracy varied with instruction and octave. These findings suggest that music educators should carefully utilize timbral instructions to avoid unintentional pitch changes.

Summary: The purpose of this study was to investigate the role of the suprahyoid and sternocleidomastoid (SCM) muscles in pitch and loudness changes during phonation in vocally healthy individuals. Results showed that the suprahyoid muscles exhibited decreased muscle activity during lower pitches and intensities compared to the natural baselines. The production of sustained /i/ vowel required more suprahyoid muscle activity than /a/ and /u/. The SCM muscles showed minimal activity in response to pitch and loudness changes. The findings also indicated bilateral asymmetry in the use of the suprahyoid and SCM muscles.
