Physicists propose new filter for blocking high-pitched sounds

Posted by in categories: health, physics

Need to reduce high-pitched noises? Science may have an answer.

In a new study, theoretical physicists report that materials made from tapered chains of spherical beads could help dampen sounds that lie at the upper range of human hearing or just beyond.

The impacts of such noises on health are uncertain. But some research suggests that effects could include nausea, headaches, dizziness, impaired hearing or other symptoms.
