According to Lindstrom, sneakers placed in a room with a scent so subtle it was considered subconscious, outsold sneakers placed in a room without the smell by 84%. Additionally, people were willing to spend on average $10.33 more for the sneakers in the scented room! Lindstrom suggests using scent to evoke childhood memories. Vanilla scent is naturally found in mother’s milk and is therefore the earliest childhood memory we can evoke through the senses. Baby powder scent as well creates a strong emotional reaction, taking us back to our earliest childhood memories. Many companies specialize in scent marketing. They can literally recreate any scent imaginable.
Sound is a powerful stimulus. Consider the fact that Harley Davidson sued Honda, claiming Honda’s Shadow Ice 1,000 sounded similar to Harley’s Fatboy. Obviously, Harley felt the “potato, potato" sound of their engines was an integral part of the Harley experience.
Consider this: In 1998, Adrian North, David Hargreaves and Jennifer McKendrick ran a test in a British wine shop to determine the role of background music in purchase decisions. For a number of days they piped in French and German music, alternating between the two. The results: on French-music days, the French wine outsold the German wine by a ratio of four to one. On German-music days, German wine outsold the French by a ratio of three to one. The same team also discovered that customers are likely to tolerate long waiting times (both on the phone and in the real world), if and when the hold/background music is enjoyable and fits our expectations.

And, by the way, the smell of that new car you leased- It’s entirely artificial according to Lindstrom. Actually, it is sprayed in to the vehicle with an aerosol can right before coming off the assembly line and is designed to last 6 weeks after the purchase. What would buying a new car be like without its accompanied new car scent?
