The sound insulation performance of the sound insulation intermediate film is near the most audible sound frequency range (1000-4000 Hz), and the sound insulation performance is 5 dB higher than that of the ordinary intermediate film. The most sensitive 1000-4000 Hz area of human ear can best reflect the difference of sound insulation performance. Compared with laminated glass with ordinary intermediate film, the maximum difference of sound insulation effect can be 5 dB (one sound level).
