We hope to be able to sell Questacon memberships again soon.
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!
