The primary function of a restaurant or cafe is to serve as a place where people can meet, socialise and enjoy culinary experiences. While some ambient noise is desirable, a balance needs to achieved where guests can feel immersed in the unique atmospheric buzz of the restaurant while also being able to converse comfortably with the people at their table and enjoy the taste sensations from the food they are served.

In a restaurant, the same characteristic sounds that are desirable become irritating when they are too loud. Conversations from neighbouring tables, activities in the kitchen, music playing from speakers can quickly amplify to intolerable levels if there is too much reflection in a space. And the louder it gets, the higher people raise their voices in order to hear one another. One survey found that noise is the second most common complaint among restaurant guests. Research demonstrates that background noise and loud music not only make it difficult for diners to communicate with one another. It can actually impair their ability to taste food and drink.

Conversely, a good acoustic environment and the right kinds of sounds have been shown to enhance and complement the dining experience and the taste of food and drink. In fact, restaurants that have excessive absorption can be just as uncomfortable, making the room feel lifeless and boring. Some ambient noise adds to the atmosphere and table privacy.
