Acoustic tubes have multiple characteristics such as pipeline acoustics, sound-absorbing materials, and control panels. The acoustic characteristics of acoustic tubes mainly refer to the influence of their pipeline structure on the conduction and scattering of sound. The influence of pipeline structure is mainly manifested in the absorption and refraction of sound. The characteristics of the sound-absorbing material of the acoustic tube mainly refer to the absorption rate of sound by its sound-absorbing material. The sound absorption rate of sound-absorbing materials mainly depends on the thickness and density of the material. The control panel characteristics of the acoustic tube mainly refer to the combination of acoustic elements on its control panel. The acoustic components on the control panel mainly include sound sources, sound control components, and acoustic computing components.The manufacturing technology of acoustic tubes has become quite mature, mainly focusing on process flow, material selection, and performance testing. The process flow mainly includes pipe forging, welding, mechanical processing, surface treatment, and assembly. The material selection mainly considers the strength, stiffness, wear resistance, and corrosion resistance of the pipe material. Performance testing mainly includes acoustic performance testing, mechanical performance testing, and thermal performance testing.
