This video documents motorcycle exhaust noise during Sunmori, short for Sunday Morning Ride, in Jakarta. It focuses on the relationship between recreational motorcycle activity and the acoustic environment of nearby homes.

The recording relates to an acoustic analysis undertaken to help a homeowner on Jalan Patiunus address noise disturbance during these gatherings. It highlights a practical concern: how to maintain a comfortable environment for rest when a home is exposed to recurring road traffic noise.

Through this field observation, Herwin Gunawan draws attention to the importance of understanding noise sources and their surrounding context before developing noise-control measures. The footage provides context for discussing environmental acoustics, residential noise intrusion, and the relationship between streets and living spaces.

For homeowners, architects, acoustic consultants, and urban designers, the video offers a starting point for considering traffic noise as part of residential design and neighborhood quality.

Part of the Herwin Gunawan Work video library, this observation connects everyday urban activity with human-centered acoustic design.
