Compared with traditional mufflers, matrix mufflers have the following advantages: they can be adjusted according to length and width during on-site installation, making installation easier and overcoming civil engineering errors; on-site splicing, simple structure, reduced on-site installation workload, and reduced installation difficulty;

There are three general performance evaluation criteria for mufflers: first, noise reduction, second, airflow regeneration noise, and third, pressure loss. Array type mufflers have improved compared to sheet type mufflers. The actual test results show that the airflow regeneration noise and pressure loss of the array muffler are lower than those of the plate muffler.

Due to the powerful acoustic performance and simple structural design of matrix mufflers. Matrix mufflers are gradually becoming an ideal equipment for noise reduction and treatment projects in rail transit, tunnels, building air ducts, and other areas.
