Alarm system performance is a critical aspect of safety. While existing research has extensively examined the influence of acoustic attributes on alarm performance, consonance's impact remains largely uncharted territory. This study bridges this research gap by investigating the effect of consonance on alarm systems. We extend our investigation to encompass not only the sound characteristics of the alarm but also the acoustic qualities of the surrounding environment, recognizing their potential impact on alarm efficacy. Prior studies consistently link consonance to annoyance levels, resulting in a negative user experience. Thus, we explore the relationship between consonance and alarm system performance, with a particular focus on modulating annoyance as an explanatory factor. Utilizing an oddball paradigm, we categorized standard and oddball sounds into consonant and dissonant types, creating four sound combinations. Participants were asked to respond to the irregularly presented oddball sounds while ignoring the constantly presented standard sounds. Our results reveal significant differences between groups, with the Standard Consonant/Oddball Dissonant (SC/OD) group displaying notably slower response times than the Standard Dissonant/Oddball Consonant (SD/OC) group. This reaction time variation aligns with differences in annoyance levels, as the SC/OD group reports higher annoyance, suggesting that reaction time discrepancies may be linked to increased arousal due to heightened annoyance.

음악의 요소 중 불협화음은 많은 연구 결과에 따라 불쾌를 일으킨다고 여겨져 왔지만, 불협화음의 종류에 따른 인지적 역할에 대해 살펴본 연구는 희소하다. 본 연구는 불협화음의 음정 간격에 따라 특정한 정서를 일으키는지, 인지 간섭에 영향을 주는지 알아보고자 두 가지 실험을 진행하였다. 실험 1에서는 불협화음의 종류에 따라 다른 부정적 정서가 느껴질 것이라고 예상하였다. 131명을 대상으로 설문조사를 시행한 결과 불협화음은 저 각성 부적정서 보다 고 각성 부적정서를 많이 일으켰다. 특히 장 7도의 음정이 다른 불협화음보다 무섭다는 응답이 유의하게 많았다. 실험 2에서는 불협화음의 불협화 정도에 따라 인지간섭에 차등적인 영향을 미치는지 알아보고자 하였다. 81명을 대상으로 색-단어 스트룹 과제를 실시한 결과 불협화음은 모두 소리가 없는 조건에서보다 응답 시간이 느렸고, 오답률 또한 높았다. 특히 단 2도는 실험에 사용된 불협화음 중 가장 느린 응답 시간을 나타냈다. 본 연구는 불협화음의 종류가 부적정서와 인지간섭에 유의한 영향을 주는 것을 보여주었다.

The music has influenced on the aesthetics, structure and symbol of the architecture from the ancient to the present. and been to be like architecture. It is important part that through the study of musical proportion by number, which is method of architectural and musical composition, resemblance can be found, music is resemble to architecture and this recognition is general as well in renaissance as architect and musician after that time. Therefore, in this background and aesthetics, the purpose of this study is to research purpose and methodology of the proportion of musical consonance and dissonance used in L. B. Alberti's architecture. At first, for the background of aesthetics this study previewed characteristic of aesthetics arranged by subjectivism and objectivism, and this musical proportion which is applicable for Alberti's architecture was defined. secondly, Alberti's architectural aesthetics (concinnitas) of the higher concept was defined by methodology of the lower concept, and this study described the application of dissonance used by the method of canon in music. thirdly, after according to characteristic of aesthetics in chapter three, proportion system was researched by the more objective, applicable unit in renaissance: roman foot and local unit differs meter in the present, Alberti's architectures was researched by the method of cannon in music.
