Firstly, what is single-sided deafness?
Single-sided deafness means you have one ear that is deaf and one ear with ‘normal’ hearing. This also applies to those who have one deaf ear and one that has hearing loss which can be improved by wearing a digital hearing aid.
What is a CROS hearing aid and what is a BICROS hearing aid?
There are two separate hearing aid solutions for single-sided deafness and these are called CROS hearing aids and BICROS hearing aids. Here is the breakdown:
BICROS Hearing Aid: A BICROS hearing aid is for people who have one deaf ear and one ear with hearing loss.
BICROS Meaning: This abbreviation stands for Bilateral with Contra-lateral Routing of Signal.
CROS Hearing Aid: A CROS hearing aid is for people with one deaf ear and one good ear.
CROS Meaning: This abbreviation stands for Contra-lateral Routing of Signal.
For those who are deaf in one ear, there are a few challenges. Here are some examples:
Following Conversations (also known as the Head Shadow Effect): This is a challenge because of the different sound frequencies we hear. For instance, low-frequency sounds are shorter in wavelength (which can go around the head) and high-frequency sounds are shorter (which are blocked by the head). Therefore, it makes it extremely difficult for those with a deaf ear to follow the conversation – without having to turn their head.
Direction of Sound: Having one good ear makes it very challenging to know which direction sounds are coming from.
What does a CROS hearing aid do?
So, how do CROS hearing aids work? In brief, in a CROS system, you wear hearing aids in both ears – even though you can’t hear in one ear. This means the sound detected by the hearing aid in the bad ear is transmitted straight to the aid in the good ear. This eliminates the ‘head shadow’ effect.
So, how do BICROS hearing aids work? In short, these work in a similar way to the CROS system apart from they are designed for those who have a hearing loss in their good ear too. The hearing aid in your good ear will also be programmed for any amplification you may need by your audiologist.
