Sound Check: How Do You Know If Your Music Is Hurting Sales?

This is Part 5 of the Sound Check series, exploring the science and practice behind retail music.

You know the exact conversion rate for each of your stores last Tuesday. You know average ticket by location, by day-part, by season. You have traffic counters at the door and dwell sensors on the floor. Your visual merchandising team can tell you which end-cap configuration moved more units in Q1.

Now: what was playing on the speakers?

Walk into any of your locations on a random afternoon. Listen. Something is playing. It has been playing since the store opened. It will keep playing until close. Over a standard retail week, that audio runs for roughly 70 hours.

Seventy hours of unexamined atmosphere.

Every other element of the store gets scrutinized. Lighting has a spec. Fixtures have a planogram. Signage gets a refresh cycle. The front table changes weekly. But the music? Somebody picked a playlist months ago, or a vendor locked in a feed when the contract started, and nobody has revisited it since.

That is not an exaggeration. I have walked stores where the manager could name every item on the feature wall but had no idea what genre was playing overhead. The audio had become invisible because nobody had asked them to pay attention to it.

Ronald Milliman ran the study that should have changed retail operations in 1982. Slower-tempo music in supermarkets correlated with longer visits and higher sales totals. He replicated the finding in restaurants four years later. Tempo influenced pace, pace influenced how long people stayed, and longer stays meant more purchasing.

That was 44 years ago.

Since then, the relationship between dwell time and purchasing has been confirmed so many times it functions as a baseline assumption in retail analytics. Researchers across psychology, marketing, and consumer behavior have studied music’s effects on shopping pace, brand perception, willingness to pay, and product choice. The findings converge: music is a variable that moves the numbers operators already care about.

And yet most multi-location retailers treat their audio the same way they treated their lighting in 1995, before anyone standardized lux levels by department.

Here is what makes this frustrating. Operators already have the instincts. Every experienced store manager has noticed the afternoon energy drop. Every district manager has walked a location and thought, “Something feels off in here.” Every VP of retail ops has stared at a store that underperforms its traffic and wondered what the gap is between the numbers and the experience.

Some of that gap is the audio.

You can hear it when the music is wrong. The store feels empty even with customers in it. Or it feels frantic when you want people to slow down and browse. Or the vibe says “college coffee shop” when the brand says “curated lifestyle.” The mismatch is obvious once you start listening for it. The problem is that listening is not yet part of the store audit.

Retailers who begin treating their audio as a performance variable, rather than a set-and-forget subscription, notice three things quickly.

First, inconsistency across locations becomes obvious. The same brand, the same merchandise, the same fixtures, but the stores feel different because they sound different. That inconsistency is costing brand equity, and nobody has flagged it because audio was not in the audit checklist.

Second, time-of-day mismatches surface. The soundtrack that works at 11 AM on a Saturday does not work at 3 PM on a Wednesday. Foot traffic patterns and customer demographics shift throughout the week. The audio stays static. Operators who track those patterns store by store start seeing where the mismatches cluster.

Third, staff behavior shifts. This one surprises people. When the audio is wrong, staff either tune it out or fight it. They turn it down, change the channel, or plug in their own phones. When the audio actually fits the store and the moment, staff leave it alone. That is a signal worth watching.

Pick your three highest-traffic stores. Walk each one at three different times: morning, mid-afternoon, and the last hour before close. Do not look at the merchandise. Just listen.

Ask yourself: does this sound like the brand? Does it match the energy of the customers in the store right now? Could you tell which store you were in by the audio alone, or do they all blur together?

Then ask your store managers the same questions. Their answers will tell you whether anyone is thinking about this variable at all. If nobody is, you have found a gap in your operations that every competitor shares.
