ACOUSTICAL ROAD PARAMETERS IDENTIFICATION
8th European Conference on Noise Control 2009, 2023Many impedance models can be used for describing the acoustical behaviour of a road. These models rely on some intrinsic parameters (2,3 or 4), which are difficult to measure in the field. Therefore, the measurement of these parameters usually requires to destroy the structure.

Room Acoustical Parameters as Predictors of Room Acoustical Impression: What Do We Know and What Would We Like to Know? [PDF]
Acoustics Australia, 2015 Room acoustical parameters are audio features, usually extracted from monaural or binaural measurements of room acoustical environments, and used to predict different aspects of the ‘room acoustical impression’.

Acoustic parameters of ocular tissues
Ultrasound in Medicine & Biology, 1985The sound velocity and the impedance of animal eyes and human eyes are measured by high frequency RF echograms (10 MHz) using a digital computer. The results are compared to literature data from 1955 to 1965, which were obtained with completely different techniques.

Acoustic Parameters of Personality
The Journal of the Acoustical Society of America, 1972Twenty-four adult males of diverse socioeconomic background were recorded as they recited a standard passage. They also recited the same passage while pretending to be excited and pretending to be depressed. The normal passages were analyzed and then synthesized by means of a terminal analog synthesizer, and then again synthesized in the following ...

Effective Parameters of Acoustic Metamaterials
Russian Physics Journal, 2018Analytical expressions are presented for the wave number, the characteristic wave impedance, and the refractive index of homogeneous longitudinal plane waves propagating in an acoustic metamaterial with dissipative losses. The metamaterial is characterized by the effective scalar material parameters: the complex density and the compressibility.

Extracting the intrinsic geo-acoustic parameters from the effective geo-acoustic parameters
The Journal of the Acoustical Society of America, 2018So far, most of the geoacoustic (GA) parameters are inverted through model-based approaches. The inverted GA parameters are not the intrinsic ones but the so-called “effective” ones. The “effective” GA parameters are model and frequency dependent and will be distorted due to model-mismatching.

Acoustic Parameters Critical for an Appropriate Vibrato
Journal of Voice, 2012A plethora of investigations have studied the acoustic characteristics of vibrato such as the rate, extent, onset (time from initiation of phonation until the first peak of vibrato), and periodicity. Despite extensive research, the degree to which various parameters of vibrato contribute to its acceptability remain unclear.The present study sought to ...

Footstep Recognition with Psyco-acoustics Parameter
APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006The characteristics of a footstep are determined by the gait, the footwear and the floor. Accurate footstep analysis would be useful in various applications, home security service, surveillance and understanding of human action since the gait expresses personality, age and gender.
