How fast does sound travel in air, measured in feet per second?

Sound travels in air at a speed of approximately 1,100 feet per second at room temperature (around 20 degrees Celsius or 68 degrees Fahrenheit). This speed can vary slightly depending on various atmospheric conditions such as temperature, humidity, and atmospheric pressure.

Understanding the speed of sound in air is crucial for audiology and hearing aid fitting, as it influences how we perceive sound, its transmission through different environments, and how hearing aids process and amplify sound signals for the user. This knowledge is fundamental to ensuring that hearing aids are tuned effectively for optimal sound quality and clarity.
