When designing audio effects for music processing, we are always aiming at providing higherlevel representations that may somehow fill in the gap between the signal processing world and the end-user. Spectral models in general, and the Sinusoidal plus Residual model in particular, can sometimes offer ways to implement such schemes.

Auditory neurons must represent accurately a wide range of sound levels using firing rates that vary over a far narrower range of levels. Recently, we demonstrated that this "dynamic range problem" is lessened by neural adaptation, whereby neurons adjust their input-output functions for sound level according to the prevailing distribution of levels. These adjustments in input-output functions i...

Average sound levels and percentage of daily dose of noise exposure were measured in the practice rooms of a university school of music, with the primary objective of determining whether sound levels in student practice rooms were high enough to warrant concern for hearing conservation. A secondary objective was to determine whether any instrument group was at higher risk for music-induced hear...

AIM  To evaluate the sound pressure level to which preschool students are exposed. METHOD  This was a prospective, quantitative, nonexperimental, and descriptive study. To achieve the aim of the study we used an audio dosimeter. The sound pressure level (SPL) measurements were obtained for 2 age based classrooms. Preschool I and II. The measurements were obtained over 4 days in 8-hour session...

A method is presented to characterize general sound-absorbing materials through a pole-based identification of the equivalent fluid. This accomplished by 1) determining extended fluid material sample transfer function (TFM), 2) acoustic response poles effective density and compressibility, 3) build compressibility from associated local response. Real pole pairs describe dissipative medium (or e...

in recent years, need to increase the convenience of trips in railway vehicles causes that train operators and manufacturers focus on reducing the noise level which is sensed by passengers. in this paper, first the state of modeling acoustic noise in cab train is discussed and natural frequencies and acoustic mode shapes are derived and then formulation of acoustic pressure in the cab will be o...

This paper focuses on identifying parameters for optimized distributions of local internal resonators to enhance the vibro-acoustic performance anti-tetra-chiral auxetic sandwich panels. The panel and its core are simulated using a full-scale finite element approach. An equivalent homogenized model is then employed reduce computational time optimization problem. based theoretical formulations v...
