As an academic lecturer, I often tell my students: "Silence sells, noise drives people away." In my doctoral research, I demonstrated that the right BPM (music tempo) can increase the average transaction value by up to 15%. So why do owners of luxury spas still play free radio, destroying the sales potential of their business?
Travelling the world — from hotels in Zurich to intimate resorts in Bali — I always pay attention to one particular detail. Not the quality of the towels or the brand of cosmetics, but the audiosphere. It's my professional obsession.
Recently, I visited a renowned spa in Warsaw. A million-pound interior, impeccable service. I lie down for a treatment, and from the speaker I hear... news about inflation, followed immediately by an advertisement for a discount supermarket chain. In a single second, my brain — instead of entering a state of relaxation — shifted into a state of analysis and tension.
From an economic standpoint, that salon had just squandered an opportunity for upselling. Let me explain why.
The Mechanism of Synchronisation (Entrainment)
In sensory marketing, a key concept is entrainment — the synchronisation of brainwaves and heart rate with an external rhythm.
- Fast tempo (Radio/Pop): Most radio hits have a tempo above 120 BPM. This is a signal to the body: "Stay alert, hurry up." In a fast-fashion clothing shop, this works — the customer makes impulsive decisions more quickly.
- Slow tempo (Wellness): In a spa, we want to achieve the opposite effect — around 60 BPM (the resting heart rate).
If you play radio, you are unconsciously rushing your client. A relaxed client spends more time in the reception area and is more willing to browse products on the shelves. A client being "hurried along" by radio wants to settle the bill and leave as quickly as possible.
Cognitive Dissonance and Price Perception
In research on the psychology of pricing, there is a concept known as priming. What we hear influences how we perceive the value of what we see.
Experiment: In one study, a wine shop played classical music and pop chart music on alternating days. When classical music was playing, customers consistently chose significantly more expensive wines, subconsciously associating the sound with luxury and quality.
Translating this to your business: if you offer a facial ritual priced at £80–£120, and in the background there is generic pop music interrupted by advertising jingles, you are creating a cognitive dissonance in the client's mind. The product is visually and price-wise Premium, but auditorily it is Economy. This clash makes the client subconsciously feel that they are overpaying.
Advertising as a "Waker" from the Shopping Trance
The greatest sin of radio in a Wellness zone is the interruption of immersion. During a massage, the client enters a specific trance-like state — their defences drop, they become more open to suggestion and they feel pleasure more deeply.
An advertising break acts like a bucket of cold water. The client "wakes up" and returns to the reality of problems, bills and everyday tasks. The business effect? After the treatment, the client won't ask about a skincare product for home use, because their mind is already occupied with what they heard in the advertisement. You have lost the opportunity for cross-selling.
SoundYou as a Sales Engineering Tool
In my lectures, I teach that music is a tool, not background noise. At SoundYou, we put this knowledge into practice. Our playlists are constructed around dynamic curves that support the relaxation process — and in doing so, they open the client's wallet.
It's not just about making things sound "nice." It's about creating an environment in which the price of your services feels entirely justified, and where the client feels comfortable enough to want to stay longer (and spend more).
Stop treating music as a free add-on. Start treating it as a member of staff who has a real, measurable impact on your turnover.
