7月18日是世界聆聽日，也是加拿大作曲家、教育家、作者及環境保護者Murray Schafer的生日。Murray Schafer 曾於1974年的夏至，在加拿大的威斯敏斯特修道院附近進行了一次24小時的田野錄音，作為其廣播計劃《加拿大聲境》的一部分。

今年夏至是6月21日香港時間下午1時03分56秒至6月22日下午1時03分56秒， 聲音圖書館團隊在孔嶺郊外進行了24小時的田野錄音向Murray Schafer致敬。

718 World Listening Day is the birthday of Canadian composer, educator, author and environmental activist R. Murray Schafer (1933-). In the summer solstice of 1974, Schafer made a 24-hour field recording at the countryside near Westminster Abby Monastery, Canada. The recording is a part of his broadcasting project “Soundscape of Canada”.

The summer solstice was from June 21 (H.K.Time 13:03:56 ) to June 22 (H.K.Time 13:03:56) this year. As a tribute to Schafer, The Library team had made 24-hour field recording at Hung Ling on that day.
