Following the tragic fire in Daedeok-gu, Daejeon, which resulted in 14 casualties, the importance of "fire forecasts" to secure the golden time for firefighting is growing. New technologies such as intelligent fire detectors that fuse multiple sensors, intelligent arc fault circuit interrupters, and reconnaissance and firefighting robots are emerging.

In particular, the sound-based early fire prediction device 'SoS HOME', which predicts initial fires by scanning acoustic flow in real-time, offers a new alternative by presenting 'acoustic landmarks' that guide escape routes through sound waves when spaces become a maze due to thick smoke and power outages.

Rosy AI, in joint research with the Electronics and Telecommunications Research Institute (ETRI), has introduced SoS HOME, the world's first sound-based AI safety device. This product is an integrated device combining a microphone, speaker, and sound field sensor, which scans the acoustic flow within a home in real-time to detect risks such as fire, intrusion, and gas leaks at an early stage. It captures blind spots missed by existing sensors and even detects initial low-heat fires, and its easy installation is expected to lead to expansion not only in homes but also in industrial and public facilities.

In particular, with the integration of Professor Cornelius Bradter's Wave Field Synthesis (WFS) technology from the Technical University of Berlin, SoS HOME goes beyond being a simple detection device. This technology, which physically reproduces sound waves through dozens of speakers, transforms the entire space into an acoustic field, providing 'acoustic landmarks' to guide escape directions with sound in crisis situations. This is not just a technology, but an intelligent design that saves lives.

Professor Bradter states that he implements "sound closest to nature" to project acoustic patterns that make the human brain feel comfortable into spaces. This creates an emotional safety net that alleviates stress and enhances crisis response capabilities. While SoS HOME can transform a living room into a concert hall, it also provides the most peaceful 'acoustic cradle' by responding to the resident's heart rate and psychological state.

This aligns with the 'prevention' emphasized by AI firefighting. Psychological stability enhances crisis response capabilities, and the qualitative improvement of living spaces lays the groundwork for reducing the likelihood of accidents. SoS Home, incorporating Professor Bradter's technology, can transform a living room into the Berlin Philharmonic Hall, while simultaneously providing the safest and most tranquil 'acoustic cradle' by responding to the resident's heart rate and psychological state.

SoS HOME is no longer an appliance, but the space itself. It is an 'intelligent fluid' that protects and guides residents through sound waves, breaking down the boundaries of a home and presenting a new paradigm for living. The moment technology harmonizes with human senses, we finally encounter the 'true meaning of home'.

According to a Rosy AI representative, they plan to build a sound-based AI ecosystem starting with 'SoS HOME'. In the future, they aim to provide customized solutions to various industries where safety is directly related, such as silver care and construction sites, and to present a global standard for 'sound security' that protects lives through technology. Their challenge to complete the safest living paradigm by connecting human senses with technology has just begun.
