A team of 2 MPhil students from the Department of Mechanical Engineering (ME) of The Hong Kong Polytechnic University (PolyU) won the 2nd Runner-up (Postgraduate Section) for their outstanding performance at the Young Professionals Exhibition and Competition held on 1 Aug 2021.

The team members, Daniel Kwong Tak Chun and Tommy Tsoi Man Ho, supervised by Dr Tracy Choy Yat Sze, competed with other local universities by a project “A Method for Online Auditory Assessment and Therapy on Pattern Recognition under COVID-19 Pandemic”. The project was concerned with designing a remote acoustic control method for health services through online conferencing software.

The COVID-19 pandemic has impacted our society in various ways. Healthcare services with a face-to-face setting are urged to search for a new delivery mode in order to ensure the safety of clients and providers. When using various video conferencing software, we often encounter different sound responses and limitations. Users' computers also have various sound performances. These restrictions greatly affect the accuracy and reliability of the health assessment or therapy. In this project, a low-cost processor was used to design the platform such that service providers could remotely play the desired audio files on the client's side without suffering from the loss of sound in terms of frequency range and loudness due to the video-conferencing software. Experimental results showed that this remote control of audio playback could be realized with a low-cost processor called microcontroller unit (MCU) based on pattern recognition on client incoming audio frequency and it was able to deliver the audio files accurately in terms of frequency and amplitude.

The Young Professionals Exhibition & Competition (YPEC) is an annual event organized by the Younger Members Section of the Institution of Engineering and Technology Hong Kong (IET Hong Kong). The YPEC acts as a dynamic platform for prospective or young engineers to exhibit their engineering projects with presentations and exhibitions. The YPEC 2021 themed “Transformer” aimed for bringing in new ideas to foster the transformation into a brand-new era.
