- Abstract
- In this paper, fire detection technique based on audible sound field variation in the security space is proposed. The sound pressure field, which is formed by a sound source in the security space, is detected from the microphone installed within the space. Since sound velocity and air density depend on air temperature, sound pressure field change is induced by the local change of air temperature in the space. This sound pressure field change can be used for early stage fire detection system. Sound pressure level (SPL) with and without local heat generation are measured and analyzed. The various case studies are performed with the finite element method simulation in anechoic and echoic space, and the experimental results at anechoic and real office rooms are analyzed. In conclusion, audible sound field variation monitoring method with the speaker and microphone set can be a good solution to the fire detection system in the security space. The proposed method will have wider applications in security monitoring service in combination with the intrusion detection method based on the sound field variation.
