The first device to perform real ear measurements was the Rastronics CCI-10, developed in Denmark by Steen Rasmussen in 1982.
The silicone probe tube system was developed at that time and has remained essentially the same ever since. That is to say a silicone tube with an inner diameter of 0.5mm and an outer diameter of 1mm. The probe also requires a handle that allows it to be connected to the microphones of the measurement system. Different attachments are available depending on the manufacturer of the measuring instrument.
Why do real measurements ?
- Because each ear canal is unique and must be treated as such.
- Real-Ear measurement ensure that the auditory structures of the wearer of the hearing aid are not damaged. Indeed, over-amplification could cause damage to the hair cells.
- In order to maximize the hearing of the wearer of the hearing aid over the entire auditory field.
- Real-Ear measurements help maximize wearer comfort (which encourages hearing aid wear)
- To maximize the benefits of the hearing aid to the wearer.
- Real-Ear measurements limit returns of hearing aids. A better fit encourages wearing the hearing aid.
- In order to demonstrate your professionalism, especially if you keep the adjustments you have made, in order to prove that you are always doing the best for your patients.
