Sound. How does it work?
Sound is energy/heat. It travels in
sound waves. Each time a particular
sound wave hits an object it reflects.
The material it hits can either magnify
that deflection or soften it. When it
softens it, it is essentially losing heat /
energy. Any soft, open celled ( porous
) material absorbs sound while the
heavier products like sound barriers
deaden sound. By deadening the
sound hits that heavy product and
looses much of it’s energy. Another
way sound travels is along materials.
The sound waves will actually travel
through various woods, metals through
vibration. So now that we know how
sound works, lets look at products and
household items that can absorb
sound….Watch the short video >
