In the bustling city of Hong Kong, noise is practically omnipresent. But have you ever considered how much more effective it would be to combat this invisible noise if we could see it with our own eyes? The Environmental Protection Department has developed a new 3D noise model—making noise visible instead of invisible! The 3D noise map displays noise levels in vibrant colors on building exteriors, allowing the public to clearly see the noise. Furthermore, they have introduced an innovative portable acoustic camera. Simply pointing a camera at a suspected noise source quickly pinpoints its location and intensity on the screen, significantly improving investigation efficiency and helping the government formulate more targeted control measures.
