1. Physiological attraction: Sound is an important non visual information in interpersonal communication, and pleasant sounds can directly stimulate men's auditory nerves, producing a sense of pleasure. This sense of pleasure is often associated with physiological attraction, as the emotions, rhythms, and tones contained in sound can evoke emotional resonance and sexual attraction in men.
2. Emotional resonance: Sound is an important tool for expressing emotions, and pleasant sounds are often clearer, more infectious, and can more accurately convey a girl's emotional state. The direct transmission of such emotions can easily resonate with men, making them feel the tenderness, kindness, or strength of girls, thereby increasing their favorability towards them.
3. Social and cultural influence: In most social and cultural contexts, voice is considered a part of female charm. In traditional beliefs, a gentle and sweet voice is often seen as a symbol of female charm, which has subtly influenced men's aesthetic preferences. When men encounter girls with pleasant voices, they will unconsciously be influenced by this social and cultural concept, and develop more favorable feelings.
