This video presents ALTA Integra’s use of an acoustic camera to investigate sound leakage in building partitions. Shared in the Herwin Gunawan Work video library, it introduces a practical method for locating potential weaknesses that warrant closer inspection during acoustic performance assessments.

The system combines a 64-microphone array with a camera to capture acoustic and visual information. Its software presents three complementary views: a sound spectrum, a spectrogram, and a sound map overlaid on the camera image. Together, these views help the team examine the frequency content, timing, and apparent location of sound.

Within ALTA Integra’s consultancy work, acoustic imaging supports the investigation of potential leakage paths and helps communicate findings to designers, contractors, and building owners. This information can guide targeted inspection and corrective work, alongside the measurements needed to assess overall sound insulation performance.

For architects, contractors, facility teams, and clients concerned about sound transfer between spaces, the video offers an introduction to how visual acoustic evidence can support problem diagnosis.

Part of Herwin Gunawan’s professional video library, this entry documents ALTA Integra’s use of acoustic investigation tools to connect design intent, construction quality, and building performance.
