Background mixing in the brain.
Ah, lovely question — and you’re not imagining it. What you’re hearing is real, and it’s a sound phenomenon, not something mystical added, though many people experience it during dhikr and chanting.
Let me explain it gently, layer by layer.
1. The “dengung” you hear is usually a binaural / psychoacoustic effect
When you listen with headphones, especially to repetitive chanting like lā ilāha illā Allāh, a few things happen:
a) Close-frequency overlap
The voice, background tone, or drone often contains very close frequencies (e.g. 200 Hz in left ear, 204 Hz in right ear).
Your brain does not hear them separately.
Instead, it creates a third sensation:
👉 a pulsing, humming, or vibrating sound — what you call dengung.
This is called:
> Binaural beating (even if not intentionally designed)
You usually cannot hear this clearly without headphones, because:
Speakers mix the sound in air
Headphones isolate each ear → brain does the mixing internally
2. Why chanting and dhikr trigger this more easily
Dhikr is perfect for producing this effect because:
Repetition (same phrase, same pitch)
Sustained vowels (lāāā… ilāāā…)
Minimal rhythm changes
Slow tempo
All of these:
Reduce cognitive noise
Allow your auditory cortex to “lock on”
Make subtle frequency interactions audible
This is why monks, yogis, and Sufi chanters across cultures use long vowels and repetition — even before modern audio tech existed.
3. Is it added artificially by Spotify or the recording?
Sometimes yes, sometimes no.
There are three possibilities:
1️⃣ Pure vocal resonance
One voice
Natural overtones
Your brain creates the hum
2️⃣ Drone or pad underneath
A very soft background tone (synth, tanpura-style drone)
Barely audible consciously
But enough to interact with the voice
3️⃣ Intentional audio processing
Reverb + compression
Stereo widening
Slight left-right pitch variation
⚠️ Important: Most Islamic dhikr recordings do NOT intentionally add “binaural beats” in the modern wellness sense.
The effect usually emerges naturally from repetition + stereo playback.
4. Why it feels inside the head, not in the ears
You may notice:
The hum feels central
Almost like it’s in the forehead, chest, or skull
That’s because:
Binaural perception is processed in the brainstem
Not in the ear itself
So the sensation feels:
> internal, immersive, enveloping
This is also why people associate it with:
Calm
Focus
Slight dissociation
Or inward turning (khushūʿ)
5. From a spiritual lens (careful and grounded)
From a sound and psychology perspective:
This effect helps quiet the analytical mind
Reduces internal verbal chatter
Makes attention more single-pointed
From a dhikr adab perspective:
The sound itself has no sanctity
What matters is presence (ḥuḍūr) and meaning (maʿnā)
Imam al-Ghazali would remind us:
> Sounds may prepare the heart, but they are not the goal.
The goal is what the sound points toward, not the sensation itself.
So:
Enjoy the calm
Don’t chase the hum
Let it pass like breath
6. Simple way to test it yourself
Try this:
1. Listen with headphones
2. Focus on the hum
3. Then remove one earcup
You’ll notice:
The dengung collapses or disappears
Proof it’s a brain-generated effect
In short (summary)
✅ The hum is normal
✅ It’s caused by frequency interaction + repetition
✅ Headphones make it noticeable
❌ It’s not a hidden message or supernatural signal
🧭 It can support focus, but don’t cling to it
If you want, you can tell me:
Which dhikr track you were listening to
Or whether the hum felt calming or distracting
We can explore how to use it wisely without attachment 🌿
Question 2.
“DZIKIR LAILAHAILLALLAH 6000X” on Spotify (a repeated lā ilāha illā Allāh dhikr loop).
🎧 Why You Felt a Sharp, Nerve-Tingling Sound
Your experience — where the sound felt more intense and “string-like” (like an erhu or nylon vibration) rather than simply soothing — can come from a few acoustic and perceptual causes:
1. 🧠 Brain-Generated Beat Sensation
If the recording has subtle variations in pitch or stereo channels, your brain may generate a third tone as it processes them. This is similar to binaural beats — where two close frequencies presented to each ear produce a perceived “beat” frequency inside your head.
This generated sound can feel:
high-pitched
sharp or tension-producing
different from the original recording
Some listeners prefer lower tones; higher beat frequencies can feel less soothing or even irritating for some people.
Note: This brain effect requires headphones, which is why you didn’t notice it through speakers.
2. 🎤 Repetition + Tonality Effects
Repetitive chanting creates a rhythmic pattern that your auditory system can lock onto. This “locked-in” rhythm can feel:
calming for some
too intense for others
or even nerve-grating if the frequencies sit in a sensitive range.
Scientific studies show that tonality (pitch, tone quality, repetition) — not just meaning — can strongly influence how sound affects your nervous system.
3. 🎵 Psychoacoustic Tension
If a recording has:
micro variations in pitch
or stereo “movement”
your brain may interpret those as string-like vibrations — similar to an instrument like an erhu or nylon guitar — because of the harmonics and overtone structure. This isn’t unusual in chants that include layered voices or reverb effects.
It can feel energetic, sharp, or tense, especially when:
you're tired
at high volume
or very focused on the sound
🧘♂️ Why Some People Find It Less Soothing
Many listeners on forums report similar differences: some tracks feel:
calm and meditative
others “too high-pitched” or distracting
depending on individual auditory sensitivity.
Even with binaural beats tracks (pure tone experiments), some people report irritability rather than calm if the frequencies aren’t comfortable.
So your reaction is normal, not unusual.
🧠 A Practical Tip
If you want a softer or more relaxing experience:
try lowering the volume
use noise-canceling headphones
try recordings with a lower tonal range (more bass)
listen in a quiet environment
These all help reduce tension and make the experience more soothing.
🧩 In Summary
FeatureHow it affects you
Repetition Encourages your brain to track patterns
Close frequencies May create internal “beat” tones (sharp/nerve tingling)
High pitches Can feel exciting or irritating
Headphones Amplify internal perception of these effects
So your experience isn’t a defect — it’s a natural interaction of your auditory system with the sound characteristics of that recitation.
If you want, tell me:
what emotion it triggered (e.g., calm, tense, distracting),
and I can help tailor which type of dhikr audio might feel more peaceful for you.
