New (stage) parameter for conductor's acoustics
The Journal of the Acoustical Society of America, 2008During fine-tuning of the stage acoustics of the main auditorium of Casa da Musica, designed by the Office for Metropolitan Architecture, in Porto (Portugal) we were confronted with conflicting comments with respect to the acoustic effect of different canopy positions.

This chapter introduces methods for the estimation of two important acoustic parameters using spherical microphone arrays: the direction of arrival of sound from a localized sound source, and the signal-to-diffuse energy ratio at a particular position in a sound field.

The Effects of Aging on Acoustic Parameters of Voice
Folia Phoniatrica et Logopaedica, 2012<b><i>Background/Aims:</i></b> There are no studies of the phonatory parameters of elderly Iranian speakers. The purpose of this study was to obtain normative acoustic data for a group of elderly Iranian male and female speakers over 70 years of age. Four selected acoustic parameters [fundamental frequency (F0), jitter, shimmer,

Nonlinearity acoustical parameter and its relation with Rao’s acoustical parameter of liquid state
The Journal of the Acoustical Society of America, 1983Sound-speed properties of liquids are calculated in terms of the easily measurable parameters on the assumption that the isochoric temperature derivative of the sound speed is the dominant factor with significant contribution to influencing the thermo-acoustic properties. Using this simple model it is shown that Beyer’s parameter of nonlinearity, Rao’s

Quantification of the Parameters of the Acoustic Reflex in Normal Ears
International Journal of Audiology, 1986Measurement of the acoustic stapedial reflex parameters has proved to be a useful tool for evaluating the function of the acoustic-facial reflex. However, there is no agreement about the definitions of the parameters; moreover, most of the data have been obtained by manual measurement methods. The authors describe a computerized analytical method which

Acoustic Parameters in Human Speaker Recognition
Language and Speech, 1990Four speaker identification tests were conducted using five female speakers known to the listeners. Starting from acoustic recordings of reiterant “ma” syllables, the perceptual importance of the following three factors was investigated: F o height, F o

Voice Acoustic Parameters as Predictors of Depression
Journal of VoiceTo analyze whether voice acoustic parameters are discriminant and predictive in patients with and without depression.Observational case-control study. The following instruments were administered to the participants: Self-Reporting Questionnaire (SRQ-20), Beck Depression Inventory-Second Edition (BDI-II), Voice Symptom Scale (VoiSS) and voice collection

Acoustic metamaterial with negative parameter
SPIE Proceedings, 2014In this paper we present theoretical results on an acoustic metamaterial beam and a bar that exhibit negative effective mass and negative effective stiffness. A one-dimensional acoustic metamaterial with an array of spring-mass subsystems was fabricated.

Robust estimation of the acoustic attenuation parameter
ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Because of the effect even additive Gaussian noise at the input has on the actual estimation of the attenuation parameter, Q, least squares estimation techniques make poor Q estimators. The errors in Q estimation may have a near Cauchy distribution. Maximum likelihood (ML) estimators based on Laplacian and Cauchy noise are derived and tested on various
