Baird's Law (principle in acoustics)

Baird's Law is a principle in acoustics that describes how sound waves travel through different environments. Specifically, it states that sound travels faster in warmer air than in cooler air. This is because, in warmer conditions, air molecules move more quickly, allowing sound waves to propagate more efficiently. As a result, on a warm day, sounds can be heard more clearly and over greater distances compared to cooler days. Understanding this principle helps explain why we often perceive sound differently depending on the temperature and atmospheric conditions.
