On which side would I benefit most from a Baha System?

Question: Near deaf in left ear, moderate loss in right ear. Which side would a Baha System benefit me? Also would it be feasible to wear on the near deaf side along with an OTE hearing aid on the moderate hearing loss side? // Eugene

Answer: Dear Eugene,

A great question but one that I can’t answer definitively I’m afraid, as a recommendation would depend very much on the exact type and degree of hearing loss you have.

If all or most of your hearing loss is conductive, resulting from issues in the outer or middle ear, a Baha System will be a good solution. It will also be useful if you are deaf in one ear and have normal hearing on the other, then the system will send sound through the bone to your hearing ear.

The Baha System can compensate for some hearing loss in the inner ear (sensorinaural loss), however, for hearing losses that are mainly resulting from problems in the inner ear there are better solutions like hearing aids, or in more severe cases, cochlear implants.

Only a hearing care professional can really evaluate your hearing loss and recommend a solution for you.

Cochlear and GN Resound have formed the Smart Hearing Alliance


Cochlear is strengthening the relationship with GN ReSound!

Last week it was announced that Cochlear Limited, global leader in implantable hearing solutions and GN ReSound, leader in Smart Hearing aids, will collaborate to develop the world’s smartest bimodal hearing solutions! The Smart Hearing Alliance will improve the hearing outcomes for more people of all ages with moderate to profound hearing loss.

GN ReSound CEO Anders Hedegaard says:

“GN ReSound is committed to advancing what is possible for people with hearing loss. This collaborative offering will help us change the lives of so many more people.”

Cochlear and GN ReSound have had a successful history of collaborating on technology and product development, resulting in the implantable hearing industry’s first bimodal solution using True Wireless. With GN ReSound’s leading 2.4 GHz wireless technology, recipients of Nucleus 6 and Baha 5 implants can stream sound directly to their ears completely without wires or bulky neck-worn components!

“This is a big step forward for our customers and professionals,” says Cochlear CEO Chris Smith. “The majority of cochlear implant recipients are bimodal users, so simplifying the management and improving the performance of their hearing solutions will be a huge benefit.”

Using the Baha solution together with a behind-the-ear hearing aid

Question: I am very excited to be getting my Baha sound processor, just waiting the 8 weeks for healing.

Currently I am wearing a BTE aid in my left ear and I am deaf in the right ear. My Baha will be on the right side. My question is, will I be able to hear on the phones at work with the Baha? Or will I still need to wear my BTE aid? (I do not hear without it).

I have been told there may be a device I can connect to my work phone that will support bluetooth, if so will it work with the Baha?????
Do you have any suggestions?

Excited to hear what I have been missing! /Teresa

Answer: Dear Teresa,

Thank you for your e-mail! The choice on how to configure the hearing aid with your Baha sound processor is something that your hearing care professional can work through.

From our experience, many people have shown that they can benefit from both the Baha and the hearing aid. This will provide you with crucial information from both sides of the head, improved performance in noise and in working out what direction sounds are coming from. If you can, it is best to stick with two hearing devices.

Just like many modern hearing aids, the latest Baha sound processors enable connection to Bluetooth devices. This will enable you to connect directly to devices such as telephones, televisions and tablets.

We have summarised how you can connect you Baha sound processor to other wireless devices here.

You asked… we answer: Can I wear the Baha Attract System on both sides?

Question: I have the Baha Attract System on my left side. But hearing in my right ear is as bad as my left ear. Can I wear two Baha 4 Attract Systems (one  for each side)? // Steve

Answer: Hi Steve,

Thank you for submitting your question, and it is great that you are using the Baha Attract System!

It is definitely possible to use the Baha Attract System on both sides. Having two hearing devices provides many benefits over just having one. Key reported benefits are better hearing in noisy situations, better localisation of sounds and better hearing from the other side, compared to wearing one hearing device (1-5). This is the same for hearing aids, cochlear implants and bone conduction hearing implants – and the Baha Attract System is no exception!

Your hearing care professional will be able to help provide more information and assess if wearing the Baha Attract System also on the right side will be the best solution for you.

Best of luck!

Will I benefit from a second Baha sound processor? You asked, we answer.

Question: Since over a year I have a Baha 3 BP110 Power at my left side and I might get a second Baha as well. Not really sure, but in a week I will speak about it with my Ear Specialist. He will tell me whether it’s smart to have a second Baha, due to the fact I still can’t hear a 100%. You see, I got bilateral hearing loss (without aid I’m able to hear from between 60 – 75 dB at both sides) and before I had the Baha BP110 I wore a BTE on both sides. Now I’ve got just one Baha, which makes it quite hard to understand people when they’re right from me.

Anyway, my question is: would it make sense if I would go for the Baha 4 instead of waiting for a power model of it, just like with the Baha 3 BP110? I’ve read that the regular model already brings better sound quality, but I’m not sure if that actually does matter in my situation. Would love to hear more about this.


Answer: Thank you for your question! There are a number layers to it which I will try and work through:

Having two hearing devices provides many benefits over just having one. Key reported benefits are hearing better in noisy situations, localising where sounds are coming from, and hearing better from the other side. This is the same for hearing aids, cochlear implants and bone conduction hearing implants alike.

Interestingly, different technologies can be combined. For example, “bimodal” hearing where an implantable technology (e.g. cochlear implants or bone conduction hearing implants) is combined with a traditional hearing aid on the other side. Despite the differences in transmission, the brain is still able to separate and then combine the sounds from both devices. It is amazing what the brain manages to do.

Given that, you can absolutely have different models of bone conduction sound processors on each side. Your hearing care professional will match and balance the loudness so that they are equalised. The one aspect to consider is the level of hearing loss you have, as it may be that you are not within the range for the Baha 4 Sound Processor and may require the more powerful Baha 3 Power Sound Processor. Again your hearing care professional will run you through this.

If you are within indication of the Baha 4 Sound Processor, then you would expect to benefit from the improved hearing performance and sound quality. The wireless technology may be beneficial for you as well. That said, even if not within range, the benefits of two Baha 3 Power Sound Processors should definitely provide large benefits over one.
