Audio and musical sonic logos are often remembered more reliably and for longer than visual logos, especially when you measure memory implicitly rather than by asking people outright.
1. Audio bypasses effortful attention
Visual logos rely heavily on focused attention ie you have to be looking!
Music and audio work even when consumers may not be concentrating:
-
- background listening
- divided attention
- habitual exposure (TV, radio, social, apps)
- fast scroll environments
This feeds implicit memory: familiarity without conscious recall.
People often feel they know a brand before they can explain why.
2. Music exploits temporal memory
Visual logos are static.
Music unfolds over time – rhythm, tone, emotion, meter, repetition.
That matters because:
-
- Our brains are fantastic at encoding temporal patterns over time
- Repetition in time = stronger neural entrainment. Humans love repetition
- Even very short motifs (2 or 4 notes) can lodge deeply
This is why we can:
-
- hum jingles, records and soundtracks from decades ago
- recognise a brand – or band, from 300 ms of sound
- feel familiarity before recognition
3. Audio triggers emotion faster than visuals
Emotion is a ‘memory accelerant!’
-
- Music accesses limbic structures rapidly
- We have little control over our emotional response to music and sound
- Emotional tagging improves recall attribution and preference
- Visual logos are usually processed more cognitively first
This gives sonic logos a head start in brand liking, warmth, and trust, even when recall tests look “neutral”.
The big caveat – where sceptics are right
Visuals win on explicit recall
If you ask: “Which logo do you remember?”
People usually say the visual one.
That’s because:
-
- Visual identity is easier to describe
- We’re trained to talk about visuals
- Explicit memory ≠ total memory impact
This may lead marketers to underestimate audio, because they’re measuring the wrong thing.
What the research consensus says
| Measure | Visual Logos | Sonic Logos |
| Explicit recall | ✅ Stronger | ❌ Weaker |
| Implicit familiarity | ❌ Weaker | ✅ Stronger |
| Emotional association | ⚠️ Mixed | ✅ Stronger |
| Long-term persistence | ⚠️ Decays | ✅ Very durable |
| Works without attention | ❌ No | ✅ Yes |
What does this mean for brands?
Sonic logos don’t always make people say
“Oh yes, that’s Brand X.”
They make people think:
“This feels familiar… trustworthy… known.”
That feeling often shows up later as:
preference without explanation
Which is exactly what brands actually want.
faster brand attribution
reduced friction
