Emotional Responses in Podcast Sound Design: A Frequency-Based Analysis of the Host's Voice Spectrum

บทคัดย่อ

        Sound design is essential in digital media for influencing listeners' perceptions of sound and their emotions, particularly in podcasting. This study looks at how podcast hosts' voice images are affected by acoustic spectrum analysis. We demonstrate that the voice of the host of the Happy Planet podcast exhibits severe oscillations in its high-frequency components, which are primarily above 2 kHz with a core frequency surpassing 3 kHz. Emotional engagement and clarity are improved by this spectral profile. On the other hand, the mid-frequency spectrum is smoother and adds to a pleasing aural experience. It spans from 500 Hz to 2 kHz, with a center frequency of approximately 1 kHz.

        According to our research, mid-frequency components offer comfort and efficient emotional transmission, while high-frequency components are essential for enhancing sound recognition and emotional expression. Optimized high-frequency spectra lead to a 22% increase in listener retention and a 30% increase in emotional connection, according to quantitative studies. Gender disparities were noted: male listeners preferred sounds with a lot of bass, whereas female listeners preferred a balance of high and mid-frequency components. This study demonstrates how frequency modulation can modulate emotional impact and listener involvement, supporting Ma and Thompson's (2015) approach that links sound qualities to psychological responses. Our findings highlight the value of customized sound design in podcast production and provide guidance for improving emotional resonance and listener experiences. This study highlights the potential of sound design to enhance digital media content while also advancing the theoretical knowledge of its role in media and communication.
