This study explores the application of biomechanics in English listening training, aiming to improve students’ listening response speed and accuracy by adjusting ear and head postures, while also enhancing their overall quality by incorporating the concept of curriculum thinking. In modern English teaching, listening is one of the core skills, and listening response time and accuracy are often used to assess students’ language proficiency. Traditional English listening training mainly focuses on comprehension of language materials and vocabulary accumulation, often neglecting the role of students’ physiological mechanisms. This research, however, introduces a biomechanical perspective to explore how optimizing ear and head postures can enhance auditory perception and improve English listening skills. In the experiment, the angle of sound reception was optimized by adjusting students’ ear and head positions to improve listening efficiency. The results showed that the experimental group with biomechanical intervention had a reduction of about 0.9 seconds in listening reaction time and a 12.8% improvement in accuracy. These findings suggest that the application of biomechanics not only directly improves students’ listening performance but also increases their engagement and interest in English learning, further stimulating their self-discipline and sense of responsibility. Through the integration of biomechanics and curriculum thinking, a more comprehensive and effective approach to English learning is provided.
