Science: Ear Trumpets

2nd class had great time making ear trumpets during a science lesson.

Before hearing aids were invented, ear trumpets were used to help hearing-impaired people. An ear trumpet collects sound from a larger area than what your own ear funnel does. These are channelled into your ear and concentrated in the small space, making what you hear through the trumpet seem louder.

The children had great fun carrying out experiments with their ear trumpets to see what the best way was to amplify sound.
