Project Description:
School lecture hall, project area is 150m². In view of the long echo of the teacher’s lectures, large-scale lectures, and insufficient language clarity, the teachers are struggling to teach, and the students often feel noisy when they work hard. Through the acoustic transformation, the intermediate frequency reverberation is designed to be 0.6 seconds (small classroom), the speech intelligibility (discourse) is clear and natural, the maximum sound pressure level difference between the front and rear rows of the full field is controlled at 4.4db(A), and it meets the requirements of environmental protection and pollution-free. We complete the installation and renovation during the weekend to ensure that the school curriculum is not affected.
