I now have solid textbook content. Let me compile the full answer.

You Likely Have a Temporary Threshold Shift (TTS) - But Act Fast

What you're experiencing after 11 hours of loud DJ music is almost certainly noise-induced hearing loss (NIHL) - specifically a Temporary Threshold Shift (TTS). Here's what you need to know:

What Happened to Your Ear

When you're exposed to loud sound for prolonged periods, the outer hair cells (OHC) in your cochlea take the brunt of the damage. Their tiny stereocilia (hair-like projections) become stiffened and less responsive.

In TTS (what you likely have): the stereocilia recover their normal mobility and hearing returns
In Permanent Threshold Shift (PTS): repeated or very intense exposure causes irreversible hair cell death

Your symptoms - one ear not hearing well, possibly muffled sounds, maybe ringing (tinnitus) - are classic TTS. It is unilateral because one ear was likely positioned closer to a speaker, or noise reached one ear at a slightly higher level. As Cummings Otolaryngology notes: "Acoustic trauma frequently is unilateral or asymmetric, and considerable variability is found in hearing loss among subjects with identical exposure."

Will Hearing Come Back?

Possibly yes, if you act now. TTS from a music venue can resolve over minutes to hours to days, depending on how much exposure occurred. However:

The window for recovery narrows quickly after noise exposure ends
A permanent threshold shift can develop over days to weeks after the noise stops, driven by toxic free radical formation and delayed cell death in the cochlea
11 hours is a very long exposure - this puts you at higher risk than a typical 2-3 hour concert

What To Do RIGHT NOW

Stop all loud noise exposure immediately - no headphones, no music
Rest your ears completely - silence is the most important first step
See a doctor or ENT (ear specialist) as soon as possible - ideally within 24-48 hours
- A same-day or next-morning urgent care or ER visit is reasonable given the severity and duration
- An audiologist can do a hearing test (audiogram) to measure the damage
Do NOT insert anything into your ear - no cotton buds, no ear drops unless prescribed

At the Doctor

The doctor may consider:

Audiogram to document the hearing loss (notch typically at 3-6 kHz, worst at 4 kHz)
Oral corticosteroids (e.g., prednisone) - these are used for sudden sensorineural hearing loss and may help if started early (within 2 weeks, ideally within 48-72 hours)
Rule out other causes: middle ear fluid, eardrum perforation (rare but possible with extreme volumes), or ear canal issue

Red Flags - Go to ER If You Also Have:

Severe ear pain
Bleeding from the ear
Sudden total deafness (no sound at all)
Dizziness/vertigo or difficulty walking
Facial numbness or weakness

The Bigger Picture

DJ venues regularly exceed 100-110 dB SPL. At those levels, OSHA considers safe exposure to be under 2 minutes per day. Eleven hours is an enormous acoustic assault. Even if hearing returns fully this time, repeated exposures like this will lead to permanent hearing loss over time.

Bottom line: Rest your ears, avoid all noise, and see a doctor first thing in the morning. The earlier steroids are started (if indicated), the better the chance of full recovery.

Experienceing tinnitus and muffle sound in one ear

This confirms your symptoms perfectly. Here's the focused breakdown:

Tinnitus + Muffled Sound = Textbook TTS Presentation

The textbooks confirm exactly what you're experiencing. As Cummings Otolaryngology states directly:

"TTS is often accompanied by other symptoms such as tinnitus, muffled sounds, loudness recruitment, or diplacusis."

Both of your symptoms - the ringing/buzzing (tinnitus) and the muffled/cottony quality of sound - are the hallmark signs of your cochlear hair cells being stressed and temporarily dysfunctional after the 11-hour noise exposure.

What Each Symptom Means

Tinnitus (the ringing/buzzing)

Noise-induced tinnitus is one of the most common causes of tinnitus overall
It's generated by damaged or overstimulated outer hair cells sending phantom signals up the auditory nerve
After a single noise event like this, it is often temporary - but it can become permanent if you re-expose your ears before they heal
Avoid caffeine and nicotine right now - both worsen tinnitus by increasing neural excitability and reducing blood flow to the cochlea

Muffled sound

This is your cochlea's hair cells being physically fatigued - the stereocilia (tiny hair-like structures) have been mechanically bent/stiffened by the vibration overload
It sounds like someone put a sock over your ear because your high-frequency sensitivity (3-6 kHz range) has dropped - the frequencies that give sound its clarity and sharpness
This is the most recoverable symptom with complete noise rest

What You Should Do Right Now (It's 3 AM)

Priority	Action
Immediate	Total silence - no music, no earbuds, no loud TV
Immediate	No headphones at any volume
Now	No caffeine, no alcohol, no cigarettes - all worsen cochlear blood flow
Morning	Go to an ENT or urgent care as early as possible
Morning	Ask specifically about a short course of oral steroids (prednisone) - the treatment window is narrow (48-72 hours is ideal, up to 2 weeks)

Why the Morning Visit Matters So Much

The cochlea undergoes a delayed wave of cell death driven by toxic free radicals - this happens over days to weeks after the original noise insult, even after you leave the loud environment. Corticosteroids, if given early enough, can reduce this secondary inflammatory damage and improve the chances of full recovery.

Tell the doctor:

"I was exposed to loud DJ music for 11 hours"
"I have unilateral muffled hearing and tinnitus"
"It started approximately X hours ago"
Ask: "Am I a candidate for oral corticosteroids for acute noise-induced hearing loss?"

Signs It's Getting Better (Good)

Tinnitus gradually quieting over the next 12-48 hours
Sounds becoming clearer and crisper
Normal conversation becomes easier without straining

Signs to Treat as Urgent

Tinnitus is getting louder or more intense
Hearing continues to worsen rather than improve
You develop dizziness, vertigo, or balance problems
Complete silence in the ear (total deafness)

The most important thing you can do right now is give your ear complete silence. Every additional decibel of sound is hitting already-injured hair cells with no recovery buffer. Think of it like a sprained ankle - walking on it keeps re-injuring it.
