Slow music in a restaurant can make your perception of time to slow down!
A study conducted by the food company Unilever and the University of Manchester wanted to find out whether background sounds affect the perception of flavor.
They found that people rated foods less salty and less sweet as noise levels increased.
When noise levels decreased, the perception of those tastes increased. The results indicate that noise has a somewhat masking effect on taste.
This is one of the reasons why airplane food doesn’t taste very good. The deafening roar of the engines can make the food taste less sweet and less salty.
This study also showed that slow music playing in a restaurant makes perception of time slow by about 13 % and also makes costumers buy up to 40 % more drinks than normal.
If you want a successful restaurant make sure you always play slow music in it.
