I forgot to answer this one. Your $400 computer with $12 headphones are playing pre-recorded sounds. Your HAs are not. With those pre-recorded sounds, you have a sound studio, mixers, recording equipment, digital music recording, re-takes, editing, etc, etc. You need to add that into the...

The rechargable batteries are all now mostly all Lithium Ion batteries. However, there are different chemistries of Lithion ion batteries. You can assume they are very similar, but not the exact same. The "radiation" you speak of is not from the battery. It is from the electromagnetic...

None of them have bluetooth. Bluetooth is too power intensive and would drain batteries too quickly. It is also a bi-directional communication protocol and therefore requires a signal being sent out (hence more power consumption). But never say never. It may be available in the future. C1

To say this means that you are implying that there is price fixing and collusion between companies to inflate prices. If there was a shred of evidence then the anti-trust g-men would be all over that. The "highly regulated" part is not corporate manipulation. Here is a link...

You are correct. It is sound processing technology that makes the cost difference. C1

I do not know what a HA's wholesale cost is. In fact, I would highly suspect that wholesale cost, like most products, is variable. If you buy 20 HAs of one type at a time they may cost X but if you buy 2 HAs at a time they cost Y. This is a very typical business model and that is the reason...

I will try and help out a little bit here. 1) I am not sure what you mean by the "actual costs of R&D"? Do you mean all R&D activities related to a company or of simply a single product? It is very hard to get line-item R&D expenditures. That said, R&D expenditures on whole are typically...

Here is more of an indication range of what is being targeted by the various hearing solutions. C1

The newest generation of MEi are moderate to severe and are targeting overlap with CIs. C1

From a different perspective, I think if you have sensorineural hearing loss, I would look into middle ear implants (MEI). They fill the void between a HA and a CI with the best MEI giving gains nearly that what a CI will without the limitaions of descrete channels. These devices have been...

Rose. My recommendation would be before you purchase any implant you look at the short and long term financial stability of the company charged to support it. Also, ask about the mean function gains that are gained in patients. As far as a clinical trial in the USA, if we are both talking...

Do not forget to look towards the future when deciding. Do your research and decide which company will have the best sound processing capabilities in a year or two when you may be able to switch out the external processor. -C1

Another option. Find a clinical trial where you don't pay anything.....this option also gives you access to the newest technology...... C1

With you explanation of mixed loss (conductive and sensorineural loss) explain why you have been looking at middle ear implants. They may work well for you. Depending upon what you get, you can get very good care and many follow-ups to make sure they work correctly. C1

Grade 2 Ti is the easiest to work with and get. C1

If you are going to use metal: Titanium Grade 1 or 2, Ti-6-4 ELI, 316L stainless, MP35N, some cobalt alloys, and a few others. But if you stick with the first 4, then you have it covered. C1

The first question you propose is a very interesting one. There have been buisness models based upon looks vs function. Just because that is the business of the prevailing companies at the moment, could a business model be made in the future that emphasizes performance be implimented? If...

I am sure you are correct. However, if you do any these actions to something that is classified as a medical device by the FDA, you are a manufacturer under the law. Medical Device Listing - 21CFR Part 807 Manufacturers must list their devices with the FDA. Establishments required to list...

Not a problem. I just want to warn you to be very careful. Even band-aids (the kind for wounds not cheap fixes to a problem) are considered Class 1 medical devices in the USA. The wooden popsicle sticks (i.e. tounge depressors) are medical devices (Class 1). Just be very careful to keep...

Ooopppppsss..Sorry. I didn't read correctly. You aren't German but have a German brochure. If you would like to have a non-public discussion on the limitations of the technology and the advantages of the technology, please email me at verruecktone at gmail dot com. C1
