Silence Is Costing You Customers: Why Every Brand Needs Sonic Branding in 2026

Open any of your last five ads, apps, or on-hold calls and mute the video. Now play just the audio. Could a stranger tell you which brand that was? For most companies, the honest answer is no. That silence has a price tag attached to it.

Every brand has spent years perfecting how it looks: the logo, the palette, the typeface, all locked down and consistent across every touchpoint. Ask the same company what it sounds like, and the answer is usually a shrug, or whatever stock track happened to fit the length of the last video edit. That gap used to be forgivable. The research says it no longer is.

The Wine Study That Should Make Every Marketer Nervous

In 1997, researchers at the University of Leicester ran a two-week experiment in a UK supermarket. They set up a wine display with four French and four German bottles, matched exactly for price and sweetness, and alternated the background music each day between French accordion tunes and German oom-pah music. Nothing else about the display changed.

On French-music days, shoppers bought roughly five French wines for every German one. On German-music days, that flipped, with German wine outselling French by nearly two to one. The study, published in the journal Nature, found that only 6 of the 44 customers surveyed afterwards believed the music had influenced their choice at all.

That's the uncomfortable truth sitting underneath sonic branding. Sound doesn't need to be noticed to work. It shapes decisions quietly, in the background, whether or not a brand has bothered to design it.

People Are Listening Whether Brands Are Saying Anything or Not

That effect scales far beyond a wine aisle. Ipsos, one of the world's largest independent research firms, analysed over 2,000 ad campaigns and found that ads carrying a distinct, consistent sonic element captured measurably more attention than those relying on visuals alone, by a factor Ipsos put at roughly 8.5 times.

Separately, audio analytics platform Veritonic surveyed consumers directly and found that 77% say they recall a brand more easily when it has a distinctive sound. Neither of these is a single agency's case study.

They're independent measurement of a pattern that shows up everywhere researchers have looked for it: sound sticks, whether or not the brand behind it put any thought into what it was saying.

Most Companies Are Still Leaving This to Chance

Here's the part that should sting a little: none of this requires a bigger marketing budget than most brands already have. It requires treating sound as a decision instead of an accident. Sonic branding isn't a jingle or a logo sound effect, it's a deliberate, repeatable audio signature applied everywhere a brand is heard.

Right now, the overwhelming majority of brand audio is exactly that: an accident. Whichever stock track a junior editor grabbed because it fit the runtime.

Whichever hold music came pre-loaded with the phone system. Whichever jingle nobody's questioned since it was written. None of it was chosen to represent anything. It's just what filled the silence.

That's not a cost-saving shortcut. It's compounding invisibility, one unbranded touchpoint at a time. Every week spent without a deliberate audio identity is a week spent:

• Letting chance decide what your brand sounds like, the same chance the wine study proved is never actually neutral

  
  

• Diluting whatever recognition exists by changing sonic direction with every new brief

  
  

• Handing the advantage to whichever competitor decides to fix this first

Sonic Branding Costs Less Than the Silence Does

None of this requires a celebrity composer or a seven-figure campaign. It requires a deliberate, research-led audio identity, built once and applied everywhere: ads, apps, hold music, notifications, in five seconds or fifty. That consistency is what turns sound from background noise into brand equity, instead of leaving it to whatever happens to be playing that day.

The wine study proved people don't need to notice your sound for it to change their decisions. The only real question is whether that sound is working for your brand, or simply happening to it.
