Difference between oxygen-rich silencer and nitrogen silencer

The difference lies in the scope of application. Oxygen-enriched silencer through the introduction of gas into the muffling cavity, through the flow of gas and absorption of acoustic energy to achieve the muffling effect, suitable for applications that require a lower noise level, such as medical equipment, laboratory equipment, etc.; nitrogen muffler through the introduction of nitrogen into the muffling cavity, the use of nitrogen's high-density and inert to reduce the propagation of sound waves and reflections, so as to achieve the effect of muffling, used for very strict requirements for noise applications, such as precision instruments, acoustic experiments and so on. It is used in applications with very strict noise requirements, such as precision instruments, acoustic experiments and so on.
