What is it about?
Have you ever visited a restaurant that looks beautiful and serves delicious food but is simply too noisy to enjoy a conversation? The sound environment is an important part of the dining experience, yet it is often overlooked in the design and evaluation of restaurants. This research explores why some restaurants feel acoustically comfortable while others are noisy and less pleasant. By reviewing 111 published research articles, the study identifies the main factors influencing how people experience sound while dining. These include the type of restaurant, its physical design and layout, sources of noise such as conversations, kitchen activities and background music, as well as the number and characteristics of diners. The research brings these factors together into a conceptual framework that explains how different aspects of a restaurant environment influence people's perceptions of acoustic comfort. Importantly, the study highlights that a comfortable dining environment is not necessarily completely quiet. Rather, the sounds within a restaurant should be appropriate for its purpose, atmosphere and customers' expectations. The proposed framework can help architects, interior designers and restaurant operators make better decisions about space planning, material selection and noise management. It also provides a foundation for future research and practical improvements in restaurant design. Ultimately, the study aims to encourage a greater appreciation of sound as an essential part of a pleasant dining experience, alongside food, service and visual ambience.

Why is it important?
This research addresses an important yet relatively underexplored aspect of the dining experience: how the acoustic environment influences people's comfort, social interactions and overall perception of eatery places. While restaurant research has traditionally focused on food quality, customer satisfaction, service and interior design, the role of sound and noise in shaping the dining experience has received comparatively less attention. What makes this study distinctive is its effort to integrate knowledge from architectural acoustics, environmental psychology, and hospitality research to develop a more comprehensive understanding of acoustic comfort. By critically reviewing 111 published articles, the study identifies the key factors influencing acoustic comfort and proposes an integrated conceptual framework covering restaurant typology, physical environment, noise sources and diners' characteristics. Importantly, the research goes beyond considering noise as simply a technical measurement by recognising that acoustic comfort is also influenced by human behaviour, dining preferences and the characteristics of the space. This work is particularly relevant as restaurants increasingly compete through the quality of their overall customer experience, where ambience and social interaction are essential considerations. The proposed framework can help architects, interior designers, restaurant operators and researchers make more informed decisions about acoustic design, space planning and noise management. Ultimately, this research encourages the hospitality industry to recognise sound as an integral component of dining quality and provides a foundation for developing more comfortable, socially engaging and acoustically responsive dining environments.
Perspectives
I consider this publication an important milestone in my research journey in architectural acoustics, particularly in expanding the understanding of how sound influences everyday human experiences in the built environment. My interest in this topic emerged from recognising that dining experiences are shaped not only by food quality, interior design and service, but also by the acoustic environment. A restaurant may look attractive and serve excellent food, but an uncomfortable sound environment can affect conversations, social interactions and the overall dining experience. Through this research, we critically reviewed 111 published articles and developed a conceptual framework to explain the key factors influencing acoustic comfort in eatery places. What I find particularly valuable is the integration of acoustic considerations with architectural characteristics, human behaviour and customer perceptions. The framework identifies the relationships among restaurant typology, physical environment, noise sources, and diners' characteristics, providing a broader perspective on acoustic comfort. I hope this publication encourages architects, interior designers, restaurant operators and researchers to recognise sound as an essential element of environmental quality. Personally, I see this work as a foundation for further empirical investigations and the development of more inclusive, comfortable and acoustically responsive dining environments.
