Studies in modal density – its effect at low frequencies (2009)
Presentation / Conference
Wankling, M., & Fazenda, B. (2009, November). Studies in modal density – its effect at low frequencies. Presented at Reproduced Sound 25, Brighton

The ability to objectively measure the reproduction quality of a small room at low frequencies has long been desired. Over many years, there have been attempts to produce recommendations, metrics, and criteria by which to define a particular room. Th...

Characterisation of the directionality of reflections in small room acoustics (2009)
Presentation / Conference Contribution

This paper investigates the extraction and analysis of temporal and spatial distribution of early sound decay. A method based on B-format signals is adapted for small rooms. It can map the spatial and temporal distribution of sound energy and its di... Read More about Characterisation of the directionality of reflections in small room acoustics.

Objective quality measurement of audio using multiband dynamic range analysis (2009)
Presentation / Conference Contribution

Ever since the very first recordings were made, people have strived to improve the recording and playback process to a point of ‘complete transparency’. However, in music production, it’s certainly the case that sound-engineers and producers employ t... Read More about Objective quality measurement of audio using multiband dynamic range analysis.

DOA estimation in car for abnormal sound localisation (2009)
Presentation / Conference
Guan, L., Gu, F., Fazenda, B., Ball, A., Yichun, Y., & Pengxiao, T. (2009, August). DOA estimation in car for abnormal sound localisation. Presented at 8th International Conference on Damage Assessment of Structures, Beijing

Spurious noise in car cabinet can be not only annoying bust also indicative of some potential faults. A small square microphone array with 4 sensors was adopted in this paper to
localize the sound source in car for fault diagnosis. A new voice activ... Read More about DOA estimation in car for abnormal sound localisation.

Noise source localisation in a car environment (2009)
Presentation / Conference
Fazenda, B., Gu, F., Ball, A., & Guan, L. (2009, August). Noise source localisation in a car environment. Presented at 8th International Conference on Damage Assessment of Structures, Beijing

Spurious noise (rattles, squeaks, etc) in the interior of car cabinets can be annoying, distractive and indicative of potential performance problems. Fault finding these problems can be difficult since the fault is intermittent and may not necessaril... Read More about Noise source localisation in a car environment.

Measurement and characterisation of faults in the intake system of a turbocharged engine using a directional acoustic probe (2009)
Presentation / Conference
probe. Presented at COMADEM 2009, San Sebastian, Spain

Engine intake system leaks are a primary reason behind unsatisfactory operational and emission characteristics of turbocharged engines. In faulty conditions, the intake mass flow sensed by the mass flow sensor does not reach the combustion chamber, r...

Subjective validity of figures of merit for room aspect ratio design (2009)
Presentation / Conference
Wankling, M., & Fazenda, B. (2009, May). Subjective validity of figures of merit for room aspect ratio design. Presented at 126th Audio Engineering Society Convention, Munich

Attempts have long been made to classify a room's low frequency audio reproduction capability with regards
to its aspect ratio. Common metrics used have relied on the homogeneous distribution of modal frequencies and from these a number of 'optimal'... Read More about Subjective validity of figures of merit for room aspect ratio design.
