| Abstract: | This dissertation discusses the ventilation noise around human. The present issue of ventilation system noise is explored. Noise from ventilation systems may affect human perception, however this has yet to be shown. As a result, the goal of this study is to establish and identify whether objective and subjective characteristics have any link. The second chapter has a full explanation. There's more on objective parameters, subjective parameters, and psychoacoustics perception. Following that, a recording of the university's classroom, lecture hall, and library was used to conduct a comprehensive sound assessment of the ventilation system noise. On various recordings, twenty-four on-site respondents and twelve laboratory respondents responded to specific questionnaires. |
