Transparent sound-absorbing panels

Frequency sound barrier noise amount of noise from the height and the sound source and the receiving point barrier between the other factors. A large component of the relationship between sound barrier noise reduction and noise frequency of greater than 2000Hz frequency acoustic noise reduction ratio of about 800 to 1000Hz intermediate frequency sound better, but around 25Hz low-frequency sound. Due to relatively long wavelength acoustic and easily diffracted from the barrier above the past, so the effect is poor. Typically, high frequency acoustic sound barrier reduces l0-15dB. Height sound barrier, according to the height doubling of distance from the sound source and the receiving point of the design, barrier, then the noise increase the amount of 6dB, in order to make better noise barrier should try to keep close to the sound barrier frequency, distance and height of the sound source and the receiving point barrier between the source or receiving point sound barrier noise amount of noise factors.
