Waves are really important for helping us understand how sound works in buildings. They affect how sound travels, gets absorbed, and bounces around in different places.
Sound Waves: Sound moves in waves called longitudinal waves. In air, sound travels at about 343 meters per second (that's super fast!) at room temperature (about 20 degrees Celsius).
Wavelength and Frequency: Wavelength is how long a sound wave is, and it's connected to frequency, which is how often the wave occurs. You can think of it like this: the speed of sound equals the wavelength times the frequency (v = λ f).
Reverberation Time (RT60): This is the time it takes for sound to fade away by 60 decibels. Depending on what the space is used for, the best times can be different. For example, in classrooms, it should be about 0.5 to 2.0 seconds.
Noise Reduction: Good design can lower how much sound travels from one place to another. With the right materials, we can reduce sound by 10 to 30 decibels, like using acoustic panels.
Materials: Acoustic panels are awesome because they can soak up 50 to 90% of sound energy.
Space Shape: Using curved surfaces can direct sound in certain ways, which can affect how clearly we hear things.
By knowing all these things, architects can design spaces that make listening and understanding sound much better.
