SUMMARY

This discussion focuses on the relationship between wind turbine noise and environmental factors such as temperature and pressure. The user seeks to analyze how air temperature influences the sound levels produced by wind turbines, utilizing measurements of wind speed, air pressure, temperature, density, and sound levels at various distances. Key formulas mentioned include E(t)=0.5*ρ*V³ and P (ThermalNoise) = k*T*B, with an emphasis on converting measurements to decibels (dB) for analysis. The suggestion to treat this as an inverse problem highlights the need for a structured approach to isolate the variables affecting noise levels.

PREREQUISITES
  • Understanding of acoustic principles and sound level measurement
  • Familiarity with thermodynamic equations related to air density and pressure
  • Basic knowledge of statistical analysis for experimental data
  • Experience with modeling techniques in environmental science
NEXT STEPS
  • Research methods for converting sound power measurements to decibels (dB)
  • Explore statistical modeling techniques for isolating variables in experimental data
  • Study the impact of temperature on air density and its effect on sound propagation
  • Investigate existing studies on wind turbine noise and environmental factors
USEFUL FOR

Students in environmental science, acoustics researchers, engineers working on wind turbine design, and anyone interested in the effects of temperature and pressure on sound levels from wind turbines.

Hello :) I'm new to this forum, so excuse me for my straightforwardness ;)
I'm working on my bachelor work and i can't find a solution.
I'm writing about wind turbines' created noise dependence on temperature and pressure. So i came to this point, that i have measurements of wind speed, air pressure, temperature, density, sound level of wind turbine at different distances. What i need is to distinguish how air temperature affects noise level that wind turbine spreads. The good advice, formula or advice on the formula would be appreciated. I hope i expressed myself clearly about the subject. Thanks in advance.

For now i have some formulas that might come in handy:
E(t)=0,5*ρ*V3, as of ρ=P/R*T
I came across this one: P (ThermalNoise) = k*T*B, but it's measured in watts, as of i need db.

Welcome to PF;
"straightforwardness" is good ;)

I'd treat this as an inverse problem.
Model the measurement process and extract the statistics of the noise for the different conditions, trying to isolate the variable you are investigating. The details depend on your data-sets ... ideally you design the experiment to perform useful measurements.
