Sudden Hearing Loss and Impact on Music Enjoyment

I am sorry you are having this medical issue. I wish you the best outcome and quick recovery time.  The key is to stay positive.  The mind is the most powerful therapy, more powerful than any appliance or apothecary.  Listen to @lalitk.  The adaptive ability of the brain is amazing, and I am like he is are sure you will find musical enjoyment with your best outcome.  
 

I am not a physician or a medical practitioner.  You should follow a clinical treatment plan as directed by your otolaryngologist.  I am a retired electromechanical medical device regulatory affairs, compliance, quality systems, and quality engineering executive with some understanding of how cochlear implants and traditional hearing aids work.  
 

A cochlear implant is an auditory nerve stimulator.  It designed as a signal processor that takes the frequency spectrum we normally hear and reduces that to a limited number of frequency channels, converting that to an electrical signal to stimulate the auditory nerve.  There is expected loss in perception of musical nuance based on this operating principle. However, the benefits of regaining hearing far outweigh this.  
 

A traditional hearing aid is a microphone, signal processor, and amplifier.  It is not a nerve stimulator.  The sound quality is dependent upon the design, execution of the design intent, and quality/cost of the device (similar to our sound systems). The signal processor compresses dynamics by design, and it will limit frequency bandwidth.  The technology is much improved over time and there are some excellent aids today.  Compared to the cochlear implant, perception of musical nuance is greater.  However, this may not be the best treatment course for you so follow whatever your practitioner tells you. 
 

Good luck and speedy recovery.  

I use hearing aids, Widex and they work fairly well. I am curious if anyone has tried building a convolution filter in Roon to compensate for the loss instead of using hearing aids?

Not in your situation, but I do have hearing loss  in the high frequency range, which has been confirmed by my ENT. I am also sensitive to loud music. I am 73 and can listen comfortably at 55-60 dbs, with brief peaks up to 65. At these low levels music did not come alive. Also had occasional ringing and clicking sounds in my ears. I took the following steps:

1. After much research purchased the JBL 4349 horn loudspeaker. Now I can listen at low levels and the music sounds full bodied. Note the JBL woofer is of the dynamic type and would not come alive at my low listening levels. I purchased 2 SVS subwoofers and set them to give me some of the bass that the JBL could not at my listening levels.  Also purchased a new preamp the Conrad Johnson Et-7 S2 which lowered the noise floor. I also tried an equalizer which did not help me.

2. The final step was to try to alleviate the ringing and clicking. I switched from my electric toothbrush to manual brushing and within a week the clicking and ringing dissipated. I am sure my electric toothbrush was doing an excellent job, but perhaps the vibrations so close to my ears was an irritant to me.  Wishing everybody happy listening and to the younger crowd, take care of your ears.

@mahler123 + 1 - I've been a hearing aid user for over 20 years now; my hearing loss will never be restored, but the EQ sure does a good job of simulating it. 

My wife, who enjoyed music so much, developed moderate hearing loss in both ears, and she now really cannot enjoy our system with hearing aids. She says, " Who is that singing? What song is that? Tone, pitch is off, as well as a clear understanding of words. The body of the music is gone. 

I miss her enjoying music along with me. I am blessed to still hear very well at 74. I no longer take it for granted.
