Elmer introduced in Metal Bar episode as linear elasticity eigenproblem solver. Pulsating Sphere problem solved using Elmer and acoupy_helmholtz. Rigid Walled Room series covered steady state field modeling
Decibel (dB) is the unit of sound measurement. One decibel is one-tenth of one bel, named after Alexander Graham Bell. Sound intensity is measured using decibel meters
Formant is a broad spectral maximum resulting from vocal tract resonance. Room formants are characteristic features of space's resonances. Formants shape sounds but are not sources themselves
Sound is a vibration propagating as acoustic waves through media. Human hearing range is 20 Hz to 20 kHz. Sound travels fastest in solid atomic hydrogen at 36,000 m/s. Sound waves can be longitudinal in gases and liquids, transverse in solids
