Is there a theoretical calculation model for noise reduction?
Thread Content
The noise level in the workshop is too high; I’ve been looking for a specialized company to provide noise reduction solutions. I studied chemical engineering; I only know that there are theories regarding heat preservation, and that these can be used for calculations. I’m not sure if there is any theory related to noise reduction, such as the sound insulation coefficients of various materials; could this be used to determine what kind of sound insulation material is needed to achieve the desired effect? Are there any fellow sailors with experience in this area?
Find a \"Chemical Process Design Handbook\" that has it
There are theoretical calculations; different materials have varying sound absorption rates, and chemical process design manuals provide specific calculation methods for this
May I ask in which chapter it is? I checked the table of contents of the manual but couldn’t find any section related to sound
Do you remember in which chapter it is? I checked the table of contents of the manual, and there is no separate chapter on noise reduction. Is it in the physical properties?
After downloading it, I checked the detailed table of contents and found that chapter. . . . . .
Chapter 5 “Environmental Protection” 7 Noise Control
The poster can refer to the HGT20570.10 standard for noise control design in process system engineering, as well as the HGT21616-1997 standard series for silencers used in common equipment in chemical plants
I’ve forgotten exactly which chapter it is; it seems to be in the section on noise control. Please take a closer look
