Miniaturized Spiral Metamaterial Array for a Ventilated Broadband Acoustic Absorber
The high-efficiency and broadband acoustic reduction performance in a miniaturized free-flow structure remains challenging in acoustic engineering applications due to the contradiction of ventilation and acoustic reduction performance. Traditional acoustic absorbers can sufficiently attenuate acoust...
