Multiple choice

Which type of wind turbine design is generally quieter?

  1. Horizontal axis wind turbines

  2. Vertical axis wind turbines

  3. Both are equally quiet

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vertical axis wind turbines generally produce less noise compared to horizontal axis wind turbines due to their different design and operation.

Multiple choice

What is the primary mechanism by which wind turbine noise propagates through the air?

  1. Convection

  2. Conduction

  3. Radiation

  4. Advection
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind turbine noise propagates through the air primarily through advection, which is the transport of sound waves by the wind.

Multiple choice
