Perceptual soundfield reconstruction (PSR) is a multichannel audio recording and reproduction framework based on time-intensity panning in the horizontal plane. A practical limitation of PSR is that the optimal directivity patterns required by the system cannot be trivially and precisely obtained in practice, and it is limited to the horizontal pla...

Recording navigable or six-degrees-of-freedom (6DoF) audio re-quires elaborate setups involving multiple microphone arrays ca-pable of recording higher-order Ambisonics (HOA) signals. Rigidspherical microphone arrays (RSMAs) are commonly used forrecording HOA. When a number of such arrays are positioned tocover a navigable area, several problems ne...

he preferred approach for multi-perspective six-degrees-of-freedom (6DoF) audio involves using multiple rigid spherical microphone arrays (RSMA) that can capture higher-order Ambisonics. RSMAs are spherically symmetric and allow the calculation of the local decomposition of sound fields over spherical harmonic functions. When multiple such arrays a...

Rooftop chillers are located in outdoor mechanical zones due to their need of fresh air intake, radiating unwanted noise to the surroundings especially due to compressor component. Acoustical barrier design is one of the most effective methods to reduce the noise in open air due to particular mechanical equipment that can not be enclosed in a room...

In recent years, many new mass transit rail systems have started to operate or planned in Turkey. The legislative regulations are developed in the last 15 years to control the acoustical comfort conditions within the stations. Reverberation in passenger circulation areas, the intelligibility of public anouncement systems, the noise due to trains pa...

Perceptual sound field reconstruction (PSR) is a spatial audio recording and reproduction method based on the application of stereophonic panning laws in microphone array design. PSR allows rendering a perceptually veridical and stable auditory perspective in the horizontal plane of the listener, and involves recording using nearcoincident micropho...
