Try the Atuund WorkstationSound wavelength determines how sound interacts with your room. Bass frequencies (20–200 Hz) have wavelengths from 56 feet down to about 5.6 feet — comparable to room dimensions. That's why bass is so affected by room modes and speaker placement. High frequencies have short wavelengths and behave more like rays, bouncing off surfaces predictably.
Effective absorption requires material that's a significant fraction of the wavelength. A 2-inch acoustic panel works well at 1,000 Hz (wavelength: 1.1 ft) but barely touches 100 Hz (wavelength: 11.2 ft). This is why bass traps need to be thick and why carpet doesn't fix bass problems.
Wavelength = speed of sound / frequency. At room temperature (20°C), the speed of sound is approximately 343 m/s (1,125 ft/s). So a 100 Hz tone has a wavelength of 3.43 meters (11.25 feet).
Bass frequencies (20–200 Hz) have wavelengths ranging from about 56 feet (17 meters) at 20 Hz down to 5.6 feet (1.7 meters) at 200 Hz. These long wavelengths are why bass interacts so strongly with room dimensions.
Atuund uses finite element method (FEM) modal analysis to model room acoustics. Built for hi-fi enthusiasts, home theater builders, and anyone who wants better sound from their speakers.
