Microphone handling noise : measurements of perceptual threshold and effects on audio quality (2015)
Journal Article
Kendrick, P., Jackson, I., Fazenda, B., Cox, T., & Li, F. (2015). Microphone handling noise : measurements of perceptual threshold and effects on audio quality. PLoS ONE, 10(10), e0140256. https://doi.org/10.1371/journal.pone.0140256

A psychoacoustic experiment was carried out to test the effects of microphone handling noise on perceived audio quality. Handling noise is a problem affecting both amateurs using their smartphones and cameras, as well as professionals using separate...

Perceived audio quality of sounds degraded by non-linear distortions and single-ended assessment using HASQI (2015)
Journal Article
assessment using HASQI. Journal of the Audio Engineering Society, 63(9), 698-712. https://doi.org/10.17743/jaes.2015.0068

For field recordings and user generated content recorded on phones, tablets, and other mobile devices nonlinear distortions caused by clipping and limiting at pre-amplification stages, and dynamic range control (DRC) are common causes of poor audio...

A glimpse-based approach for predicting binaural intelligibility with single and multiple maskers in anechoic conditions (2015)
Presentation / Conference
Tang, Y., Cooke, M., Fazenda, B., & Cox, T. (2015, September). A glimpse-based approach for predicting binaural intelligibility with single and multiple maskers in anechoic conditions. Presented at Interspeech 2015, Dresden, Germany

A distortion-weighted glimpsing metric developed for estimating monaural speech intelligibility is extended to predict binaural speech intelligibility in noise. Two aspects of binaural listen- ing, the better ear effect and the binaural advantage, ar...

Fast time domain modeling of surface scattering from reflectors and diffusers (2015)
Journal Article
Cox, T. (2015). Fast time domain modeling of surface scattering from reflectors and diffusers. ˜The œJournal of the Acoustical Society of America (Online), 137(6), 483-489. https://doi.org/10.1121/1.4921675

Time-domain prediction models have been developed for auditorium reflectors and room acoustic diffusers. The models are time-domain equivalents of the single-frequency formulations that exploit the Kirchhoff boundary conditions. Consequently, they a...

A record “longest echo” within the Inchindown oil despository (2015)
Journal Article
Cox, T., & Kilpatrick, A. (2015). A record “longest echo” within the Inchindown oil despository. ˜The œJournal of the Acoustical Society of America (Online), 137, 1602-1604. https://doi.org/10.1121/1.4908218

In 2013, Guinness World Records awarded tank number 1 at the Inchindown oil despository, Ross-shire, Scotland, the record for the “longest echo” at 75 s. Guinness World Records calls it the longest echo because that was the name of the record that wa... Read More about A record “longest echo” within the Inchindown oil despository.

Microphone handling noise database (2015)
Dataset
Kendrick, P., Jackson, I., Fazenda, B., Cox, T., & Li, F. Microphone handling noise database. [Dataset]

Microphone handling noise can reduce the quality of audio recordings. A perceptual study into this effect has been carried out and the subjective response quantified. This database contains audio recordings of handling noises from 8 different micro... Read More about Microphone handling noise database.

A survey of acoustic conditions and noise levels in secondary school classrooms in England (2015)
Journal Article
Shield, B., Conetta, R., Dockrell, J., Connolly, D., Cox, T., & Mydlarz, C. (2015). A survey of acoustic conditions and noise levels in secondary school classrooms in England. ˜The œJournal of the Acoustical Society of America (Online), 137(1), 177-188. https://doi.org/10.1121/1.4904528

An acoustic survey of secondary schools in England has been undertaken. Room acoustic parameters and background noise levels were measured in 185 unoccupied spaces in 13 schools to provide information on the typical acoustic environment of secondary...

A source separation evaluation method in object-based spatial audio (2015)
Book Chapter
Liu, Q., Wang, W., Jackson, P., & Cox, T. (2015). A source separation evaluation method in object-based spatial audio. In 2015 23rd European Signal Processing Conference (EUSIPCO) (1088-1092). IEEE. https://doi.org/10.1109/EUSIPCO.2015.7362551

Representing a complex acoustic scene with audio objects is desirable but challenging in object-based spatial audio production and reproduction, especially when concurrent sound signals are present in the scene. Source separation (SS) provides a pote... Read More about A source separation evaluation method in object-based spatial audio.
