Deep Neural Network Based Blind Estimation of Reverberation Time Based on Multi-channel Microphones

Lee, Myungin,Chang, Joon-Hyuk S. Hirzel Verlag 2018 Acta acustica united with Acustica Vol.104 No.3

<P>Reverberation causes a performance degradation in distinct speech processing. For this reason, quantitatively estimating the amount of reverberation from the signal received by the microphone has been an important task for characterizing room acoustics and compensating for degradation due to an algorithm. In this paper, a novel method that estimates the reverberation time (T-60) based on multi-channel microphones using a deep neural network (DNN) is proposed. Each channel's distribution of the decay rates for each frequency and the generalized cross-correlation with phase transform (GCC-PHAT) between the microphones are adopted as the input feature vectors for DNN training. Those refined features enable the DNN composed of multiple nonlinear hidden layers to learn the nonlinear relationship that labels the reverberation time from the input features, which is known to be challenging with low-order features. The proposed algorithm is evaluated with extensive noisy conditions, and the results show the advantage of employing multi-channel signals with spatial features when compared with conventional methods.</P>

As a policy response to an aging population, the Korean government has implemented community care, integrating housing, health, nursing care, and other care services. Medication management services are included in community care programs as an area of chronic disease management; however, till date, the content and methods of this service have not been structured systematically. In this study, we aimed to obtain recommendations for the development of a medication management system in Korea by analyzing and comparing with the medication management systems in the UK, Japan, Singapore, and Australia. These countries currently provide medication management services and have strict qualifying criteria for patients. Common qualification criteria for service recipients include, two or more chronic diseases, or high-risk medications. The system by which pharmacists obtain medication records differs depending on the medical coverage system adopted by the country. In countries that have adopted a, such as the UK and Australia, medical information is obtained through the national public health record platform. Singapore also utilizes a similar national health record platform. In Japan, which has adopted a National Health Insurance system, each patient has a personal medicine note. Pharmacists and other medical staff can obtain patient information through this handbook. Through this study, it was found that community care and medication management services have been established according to social and geographic conditions in each country.
