Hello everybody
I'm new here and it's my first post. First, I'm French and my English is far to be perfect, so I apologize in advance if I'm hard to understanding.
I'm 40 and hard of hearing with -80 dB on mediums and a bit better in low and high frequencies, see my hearing profile and hearing aids features :
Now, I listen music with this combo :
- Smartphone Zenfone 8 pro with UAPP installed
- DAC FiiO Q3
- Symetric wire jack 2.5 mm
- IEMs Erdre Audio EA 502
I turn the DAC's volume potentiometer to 80 % with 16 ohms impedance IEMs. I need a very loud sound
I like UAPP because this app allow me to feature signal in accordance with my hearing profile by using parametric equalizer. Here is the feature :
The first picture is my favourite feature at this moment ( I didn't found the perfect trebbles feature for now )
The second picture is more clearly ( I improved weakness of my IEMs ) but corrections are positive and , of course , I ear distorsions.
This combo allow me to listen music with a very good quality ( Good quality compensate for my hearing loss ).
I'm here because I'm looking for help in order to make Hi-Fi hearing aids.
I've to found a portable device such a smartphone wich be able to capture sound, apply DSP and re-produce. Everything should take 1 ms or a bit more ( I've to avoid shift between lips reading and signal in my ears ).
This device must have a full-duplex USB port ( or 2 USB ports , I don't know what's the best feature ).
For input signal, I would like use large ( wire ) cardioid stereo microphones with a DCA. Large cardioid seems accurate in order to reproduce ear flaps, whiches can't assume their role because I wear the IEMs. These microphones will be stacked on each ear flap, the best compromise for natural capture and feedback avoidance.
I found those, but I'm a noob and I don't know if they are accurate:
For output signal, I will use a DAC with IEM's.
I want High quality audio ( 24 or 32 bits ). 64 bits would be nice but I'm not sure I'm able to ear difference between 32 and 64 bits.
I don't have a lot of knowledge about electro-acoustic and my challenge can't be take up without your help.
Which combo advice you to me ?
A big THX in advance
EDIT: By now the equalizer works for both left and right ear. It works well by reporting balance output to left but I would like to have one equalizer for each ear because they haven't the same profile.
