Non-Electric Hearing Aids—General Information Before the discovery and harnessing of electricity, non-electric (mechanical or acoustic) hearing aids were all that were available to help hard of hearing people hear better. Some of these devices helped people hear and others were basically quack devices. Then as now, you had to be careful and do your own research. The gullible were quickly separated from their money by slick salesmen. There are 4 classes of non-electric hearing aids in the museum. They are: - Ear trumpets
- Conversation Tubes
- Auricles
- Ear Inserts
You can gain an overview of each of these by clicking on the links to the 4 classes below.
