Research Fellow /Associate /Assistant in Acoustics

by

Job Description:

Proposed Input:

We are looking for a full-time (5 days a week, 8 hours) Research Fellow/Associate/Assistant for 12 months appointment to commence in September 2019 or as soon as possible.

Project: The research objective of this proposal is to prove the conjecture that the use of porous media with some novel structures can improve noise reduction at low frequencies. Emphasis will be placed on the acoustic characterisation of porous media and acoustic metamaterial.  The proposed study is based on the development of numerical models for the proposed design, and their validity will be confirmed by sound transmission and absorption experiments.

This project involves diverse theoretical as well as applied facets of porous materials and numerical prediction as well as acoustics.  The candidates are preferred to have prior hands-on experience with theoretical, numerical and/or experimental background in acoustics.  This position will also assist in and contribute to project management to ensure the successful completion of the proposed work.  Specifically, this position will be responsible for theoretical and experiment development in acoustics research, development of numerical models, data analysis and reporting to MOE.  S/he will assist in and contribute to other aspects of the research and dissemination of the results. S/he will contribute to the preparation of scientific manuscripts and/or other literature for publications.

Domain: Architecture, Urban planning, Acoustics, Engineering

The appointed RA will be involved in the following tasks:

  • Assist in and contribute to all the tasks related to publications in the domain.
  • Participate in research and writing of articles
  • Assist in and contribute to development, design, and setup of the experiments
  • Develop numerical modelling (using COMSOL) and experiment study
  • Analysis and collection of data, and graphical representation of information using suitable tools (such as MATLAB, etc.)

Job Requirements:

  • Bachelor’s (preferably Master’s) Degree in Architecture, Mechanical Engineering or another relevant engineering for research assistant and associate, respectively
  • Ph.D. Degree in Architecture, Acoustics or another relevant engineering for research fellow position
  • Knowledge of acoustics and its numerical simulations and experiments.
  • Experience in research work and writing
  • Skilled in FEM modelling and data analysis using COMSOL and MATLAB, respectively
  • Capacity to work independently
  • Management skills

Compulsory Information to be included.

Interested candidates should contact Siu-Kit (Eddie) LAU at slau@nus.edu.sg with the following:

  • Cover letter specifying your research interests and experience
  • CV (including GPA/CAP ranking), which should include names and contact of 3 referees
  • Most significant publications, if available (no more than two)
  • A copy of official transcripts (Bachelor degree and Master degree)

Only shortlisted candidates will be notified and will be asked to complete and submit the NUS Personal Data Consent for Job Applicants to the contact person indicated in the advertisement.

An investigation of acoustic treatment for children in a classroom of an elementary school

by

The South China Univeristy of Technology and Dr. Lau of Armstrong have compared the objective acoustic parameters and students’ subjective responses before and after an acoustic treatment in an elementary-school classroom. Acoustic treatment was done by installing sound absorption materials on the ceiling of the classroom for control of sound reverberation. The effects of reverberation time on children’s speech recognition have also been investigated. Results show that (1) the objective acoustic parameters in the classroom were obviously improved; (2) the subjective loudness of different types of noise sources, that students experienced in the classroom, were reduced; and (3) the speech intelligibility was significantly improved in the classroom after the acoustic treatment.
