I recently became curious about the current state of the art in headphone correction and HRTF measurement and have been trying out 3D audio software. As part of this I have tried to find a cheap real ear measurement system similar to those used for fitting hearing aids but was unsuccessful. The Mini DSP system doesn’t have the correct adapters. I wanted a personal linear phase measurement system for headphone correction and playing with HRTF filters.
If I was a premium headphone company I would consider offering this service to my customers just like all the Audiologists on the high street do for hearing aid fitment.
Does anyone know if this is happening as it is quite easy to set up with a PC a couple of ADCs and DACs and some speakers and some probe tubing on a microphone? You would have to use MATLAB or similar as a one off but a simple app would be usable by non tech types in a shop or at home for custom fitment. It could even be built in to some IEMs.There is also the option on using an in situ audiometry target - can see no sign of that anywhere at the moment?
