Sound of Real and Fake Gold and Silver 🎬

The sound of metals depends on their density, elasticity and crystalline structure. Pure gold and silver produce a clear and short sound because they are dense and quickly absorb vibrations. Copper prolongs the sound and gives it a buzzing timbre, but combined with nickel the sound becomes annoying and less harmonious. Iron has a metallic and dry sound, because it is more rigid. Tungsten generates a dull and muffled sound, without resonance.
