Catching Sounds

Sound vibrations can be 'collected' and concentrated to make soft sounds louder.

How it works

Listen to ambient sounds through plastic funnels that channel sound waves to the ear.

Things to try or ask around the exhibit

Do some noises seem louder or softer than others?

Background

The funnel collects sound waves and concentrates them into your ear, making noises sound louder in volume.

Finding the science in your world

Some animals have large outer ears that improve their hearing, so they can escape from predators or find food.

In the past, hearing funnels were used by people with hearing disabilities and by courting couples who wanted to keep their conversations private!
