Changes of AI receptive fields with sound density.
Primates engage in auditory behaviors under a broad range of signal-to-noise conditions. In this study, optimal linear receptive fields were measured in alert primate primary auditory cortex (A1) in response to stimuli that vary in spectrotemporal density. As density increased, A1 excitatory receptive fields systematically changed. Receptive field sensitivity, expressed as the expected change i...
متن کاملTraceable sound power measurements in essentially diffuse or free fields
ABSTRACT Current methods for the determination of sound power such as the ISO 3740 series do not have a direct traceability to a primary standard. The different methods are regarded as equal, but they do give results with systematic differences. One task of the European project “EMRP JRP SIB 56 SoundPwr” has been to develop and investigate traceable and consistent methods for sound power measur...
متن کاملInversion of spinning sound fields.
A method is presented for the reconstruction of rotating monopole source distributions using acoustic pressures measured on a sideline parallel to the source axis. The method requires no a priori assumptions about the source other than that its strength at the frequency of interest varies sinusoidally in azimuth on the source disk so that the radiated acoustic field is composed of a single circ...
متن کاملGeneralized acoustic energy density based active noise control in single frequency diffuse sound fields.
In a diffuse sound field, prior research has established that a secondary source can theoretically achieve perfect cancellation at an error microphone in the far field of the secondary source. However, the sound pressure level is generally only reduced in a small zone around the error sensor, and at a distance half of a wavelength away from the error sensor, the averaged sound pressure level wi...
متن کاملPower Density
4 Digital Object Identifier 10.1109/MDAT.2017.2667640 Date of current version: 23 February 2017. Power density is one of the most stringent constraints in designing on-chip systems. This seems surprising at first sight considering that the switching energy of a transistor in current CMOS technology is only about a 1/1000 of what it used to be a quarter century ago. Still, power density is rap...
