Which surfaces tend to reflect more sound?

Sound travels as waves and how a surface handles those waves depends on its texture and density. A hard, smooth surface doesn’t absorb much energy; it acts like a mirror for sound, so most of the energy is bounced back. That creates stronger reflections and more reverberation, which is why you can hear an echo or a clear reflected sound off tile, glass, or bare walls. In contrast, soft, porous materials have many tiny pockets and irregularities that trap and scatter sound energy, turning it into heat and dissipating it rather than returning it as a distinct reflection. Absorbent foam and thick curtains are specifically designed to soak up sound, reducing reflections and dampening echoes. So the surface that tends to reflect more sound is hard and smooth.
