Summary

The Hearing Amplifier.

When it comes to buying a hearing aid, prices are a bit steep. The electronics that go into manufacturing a powered hearing aid are micro-sized, and therefore very expensive. There are no electronics required with set of hearing aids, making them a great alternative to high priced electronic ones.

These simple hearing aid alternatives are much more eco-friendly than electronic ones. They are fully recyclable and remove the need for expensive and environmentally detrimental batteries.

Things To Look Out For

  • The highest possible print resolution is recommended. This will ensure that sound amplification is at a max. The rough and bumpy walls produced by a low resolution print will scatter sound waves and direct less sound into the ear.

  • It is best to print this item with Nylon, but ABS will work very well also. PLA will work, but it will not amplify the sound as well. The reason for printing in Nylon is because it is harder than the other plastics, meaning the amplifier walls will reflect more sound into the ear, rather than absorbing it.

-A tip for producing the best seal with the inner ear, is using a spare set of rubber fittings from a pair of in-ear headphones to place on the ends of the hearing amplifier. Likely not all kinds of fittings are going to work, but it is worth a try.

Help From You

This Item is a work in progress. Please print off a copy and message me about how they fit. I would like to make them as comfortable as possible for everyone.

i like your design. i am working on a non electrical form of funneling sound in a more directional way.. kind of simple background noise elimination or reduction system.. while also amplifying targeted sound.. i am thinking something like animal ears which can turn to hear in different directions.. but augmented to enhance directional sound where the ear is aimed. and funneling it into the ear canal.
btw.. something that might be usefull is to print calipers (you can find them on thingiverse.. i found one that is very good.. and used that to measurd various parts of the ear, to do a fitting before printing.

I invite everyone to print these off, and let me know how they fit. These likely wont fit everyone, so I will need to make a few versions.

What scale should this be printed ?

Hi waran14. They should be printed in full scale, 1:1. My 3d printer is down unfortunately, so please give me some feedback on how they fit. If the format needs to be changed for easier printing let me know as well. I welcome your suggestions.
