Acoustics and Audio Engineering combined with VR Environment
Thinking about immersive listener? Our acoustics and audio engineering group are doing some research in collaborating sound reproduction by well known acoustics-based approach and audio processing with reproduction techniques. In this research, we are affiliated with some institutions i.e. Institut Teknologi Bandung, Institut Teknologi Sepuluh Nopember, Universitas Negeri Sebelas Maret, the University of Salford, and Puslitbangkim PU. The research topics are always available for undergraduate and master students in all year-around. Co-supervising with another institutions are also possible.
Building Acoustics & Auralization
Conducting RIR measurement with applicable tools from uni to omni directional speakers and microphone or combined. Spatial RIR are also included by using Figure of Eight Microphone processed for ambisonic files in first and high orders. Computer simulation, auralization as well as subjective assessment are also included to investigate.
Audio Signal Processing & Reproduction
Audio signal processing and reproduction are further process from acoustic measurement either from field recording or RIR analysis. The research will be preferably handling with MATLAB or Phyton. Otherwise, any Digital Audio Workstations i.e. Audacity / REAPER / Adobe Auditon can also be used as long as the algorithm can be clearly explained.
Soundscape & Perceptual Hearing
Soundscape for indoor and outdoor environment is a brand-new science in acoustics scope. The research will include spatial recording with ambisonic microphone, audio processing with DAW softwares and plug-ins, and audio reproduction over headphone or configured speakers to assess listeners' perception of sonic environment.
Noise Environment and Vibration
The research includes noise measurement (SPL) and mapping to provide possible recommendation for architectural sites or building enclosures. Noise source emitted by vibrating structures or machines which can negatively effect the human hearing system or productivity in office or industrial area can also be studied.
We have different requirements for different sub-topics. However, these basic conditions must be fulfilled by prospective students that you have to;
- have a good understanding in Fundamental of Acoustics (obtained a mark B or higher in related course)
- have a high curiosity to learn and explore with related topics mostly by yourself
- be able to join 2-weekly presentation of your progress together with another students in similar topics
- be able to finish your work in a proper time as firstly scheduled with your supervisor
- be able to write a min. 4-page summary of your work in English
We would be glad and more consider if you have experience with;
- room acoustic measurement, field recording, with any tools or instrument and method;
- SPL measurement indoor or outdoor;
- acoustics simulation for room acoustics or noise mapping;
- audio processing with any DAW software and plug-ins;
- basic programming with MATLAB or Phyton;
- basic programming with C# or knowledge in Game Engine Softwares.
Virtual Auditory Reality
This research conducts spatial audio reproduction in First Order Ambisonics converted into Binaural Sound stimuli and VR environment design. Level calibration, assessment of audio visual quality, blind investigation of directionality, investigation of listeners' perceptions, preferences, and reactions are incorporated. The AV reproduction will be covered by DAW software, 3D Design software (SketchUp / Maya / 3D Max), GameEngine (Unity / Unreal) with GVR Plug-ins, and visualization through HTC Vive.
Acoustics instrumentation research generally aims to research potential product which utilizing acoustics phenomena for human or prospective users. The products can have very specific or large scope. For instance, the sound guidance for blind people by installing PIR sensor in their stick to keep a distance between the people with another solid matters. The audible sound will emit as the alarm for blind people in an improper condition. You can propose your own idea and any feasible idea will be gladly supervised.
