The study for the influence of acoustic silencer foam on the output of sound based on the software of room EQ wizard

Stimulated by market demand and technological progress, the audio industry is booming. Many high-fidelity earphones are no longer satisfactory with simply providing customers products but tend to provide more opportunities adjust their own tuning, one of which add different acoustic silencer foam. This study begins introducing types development history. After that, specific research content raised questioning prevailing perception foam in earphones. By comparing analyzing differences reflected frequency response curves headphones equipped foam, it concluded that smaller cells presence membrane will increase its ability reduce loudness at high frequency. reveals two significant characteristics affect performance provides a reliable theoretical basis for tuning technology
