"Spatial Impulse Response Rendering II: Reproduction of Diffuse Sound and Listening Tests" Journal of the Audio Engineering Society, vol 54, no. 1, 2006
|
The assumptions made in the first SIRR-JAES paper are bolstered here, and a new method to diffuse sound is presented. The quality obtained with SIRR and Ambisonics is studied with formal listening tests in anechoic chamber and in listening room. |

"Segregation of Two Simultaneously Arriving Narrowband Noise
Signals as a Function of Spatial and Frequency Separation" 8th
International Conference on Digital Audio Effects, DAFx'05, September
20-22, 2005, Madrid, Spain.
|
Listening tests are conducted in order to study the
perceptual segregation and integration of two simultaneously arriving
narrowband noise signals as a function of their spatial and frequency
separation. This study is also related to the perception of complex sounds.

"Detection of subwoofer depending on crossover frequency and spatial angle between subwoofer and main speaker". Audio Engineering Society Convention paper 6431. Presented at the 118th Convention 2005 May 28-31, Barcelona, Spain.
|
Listening tests are conducted to find the highest crossover frequency
where the listener does not detect the subwoofer.
Four different distances between the woofer and the main speaker were employed.

"Localization of Virtual Sources in
Multichannel Audio Reproduction" IEEE Transactions on Speech and Audio
Processing, vol 13, no. 1, 2005
|
The directional quality of first- and
second-order Ambisonics and a spaced microphone technique is tested in
5.0 and octagonal listening. Listening tests and binaural auditory
modeling are conducted.

"Multichannel reproduction of low frequencies" Baltic-Nordic
Acoustics Meeting, 2004 June 8-10 2004, Mariehamn, Åland, Finland.
|
In this paper, we have studied different techniques for audio
low-frequency reproduction obectively and subjectively. A novel method
where low frequencies are reproduced using wave-field synthesis showed
promising results.

Situations: Selection of Binaural Cues Based on Interaural Coherence,"
Journal of the Acoustical Society of America, vol. 116, no. 5, pp.
3075-3089, 2004.
|
An auditory modeling mechanism for extraction of binaural cues
corresponding to localization of concurrent sound sources as well as
sources in precedence effect and room conditions is proposed.

"Training of Listeners for Evaluation of
Spatial Attributes of Sound," in Proceedings of The 117th AES
Convention, preprint 6237, San Francisco, CA, USA, October 28-31, 2004.
|
Auditory source width (ASW) and listener envelopment (LEV) in three
different acoustical environments was studied. Familiarization of the
listeners with the attributes was necessary but further experience did
not change the evaluatioin. The results indicate that both measures are
correlated, source-dependent, and do not correspond to standardized room
acoustical parameters.

"Psychoacoustic Cues in Room Size Perception,"
Audio Engineering Society Convention paper 6084. Presented at the 116th Convention 2004 May 8-11, Berlin, Germany.
|
Virtual realities with different reverberation lengths and levels are generated, and the listeners judge the size of the room. It is found that the level does not affect the perceived size at all, the only significant attribute is the length of the reverberation in this case.
