Multimodal Hong Kong: A review of policies regarding soundscape and smellscape of Chinese temples

Many people in Hong Kong regularly visit Chinese temples, and see this not necessarily as a religious activity, but as a traditional practice. Temples represent the local intangible cultural heritage. The dense urbanity and mixed population characterise Hong Kong and make it valuable to study its sounds and smells. Most temples existed earlier than modern urban areas, which grew around them. The temple soundscape consists of drums, bells, coin donations, ventilation fans, as well as chanting, especially during festivals. The smellscape consists of ritual burning of incense and paper, fruit offerings, and building materials e.g., wood and cement. The burning causes particle pollution, health concerns, and residential nuisance, that may conflict with the wish for sustaining a valuable heritage. Smells and air quality have recently become debated, raising the question of the need for a specific regulatory framework. There is currently a lack of official provision that directly protects the sounds and smells of these temples in Hong Kong. This paper reviews the current state of Hong Kong policies in regard to soundscape and smellscape, with comparison to China and France, because of the latter's progressive agenda in preserving sensory heritage in the countryside.
