The study aims to diagnose the sound pressure levels inside incubators in a controlled environment under free-field conditions. tests were carried out semi-anechoic room standard UNE-EN ISO 3745:2012/A1:2018 three different operating states: off, on, and on with temperature alarm triggered. Sound analyzed models of incubators, both outside. main noise indices corrected equivalent continuous lev...

Sound synthesis methods aim at the auralization of the sound produced by a physical sound source as it is heard by a listener at an arbitrary location. In order to suit the synthesis approach, the physical source is represented by an acoustic equivalent source model which behaves similar in the far field. However, it is not straightforward to determine the number, the position, the type, . . . ...

We examined the crossmodal effect of the presentation of a simultaneous sound on visual detection and discrimination sensitivity using the equivalent noise paradigm (Dosher and Lu, 1998). In each trial, a tilted Gabor patch was presented in either the first or second of two intervals embedded in dynamic 2D white noise with one of seven possible contrast levels. The results revealed that the se...

For audiovisual sensory events, sound arrives with a delay relative to light that increases with event distance. It is unknown, however, whether humans can use these ubiquitous sound delays as an information source for distance computation. Here, we tested the hypothesis that audiovisual delays can both bias and improve human perceptual distance discrimination, such that visual stimuli paired w...

We read with interest the recent issue of Critical Care in which Darbyshire and Young [1] reported on noise levels in five different ICUs and demonstrated average sound pressure levels far above the World Health Organization recommended standard of 35 dB LAeq (A-weighted energy-equivalent sound pressure level in decibels). Although their article provides an interesting insight into the ICU soun...
