Beschreibung:
Over the course of time, hearing aid technology has made enormous progress, thus making the lives of hearing-impaired people much easier.
Before 1878 there were practically only mechanical hearing aids based on the sound funnel principle.
The photo shows Madame de Meuron, born in 1882 in Bern, Switzerland; died in 1980 in Riggisberg. She preferred using an ear trumpet throughout her life, arguing that then she had to hear only what she wanted to hear.
Information and ideas:
Elementary school students can use paper to easily recreate the old hearing aids in the form of ear trumpets. In this way they can understand the simplest effect of sound amplification.
Relevant for teaching:
Hearing damage/hearing impairment
How hearing works
Sound transduction
