AI Thread Summary
The discussion focuses on the function of vent silencers in reducing and controlling noise levels, specifically referencing sound pressure level (SPL) and sound power level (PWL). It highlights the importance of octave bands in understanding noise characteristics and mentions the impact of diffuser pipes on sound distribution. A participant expresses confusion over the clarity of the original question, suggesting a need for better articulation. The conversation emphasizes the relationship between noise reduction and frequency, particularly noting maximum noise creation at 2 kHz. Overall, the thread seeks to clarify technical aspects of vent silencers and their acoustic performance.

we speak about vent silencer and octave band and sound pressure level and sound power level and diffuser pipe

No offense, pal, but that makes absolutely no sense. Can you try to articulate your question in a manner that we can read?
 
vent silencer use from reduction and control noise and from inverse square low and max noise create at frequency 2 KHz
 
comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
