Passive Communication with Ambient Noise [PDF]
SIAM Journal on Applied Mathematics, 2021 Motivated by applications to wireless communications, this paper addresses the propagation of waves transmitted by ambient noise sources and interacting with metamaterials. We discuss a generalized Helmholtz-Kirchhoff identity that is valid in dispersive media and we characterize the statistical properties of the empirical cross spectral density of the

Frontiers in Virtual Reality, 2021 Irrelevant ambient noise can have profound effects on human performance and wellbeing. Acoustic interventions (e.g., installation of sound absorbing materials) that reduce intelligible noise (i.e., sound unrelated to the relevant speech, including noise ...

The effects of aerator noise on the swimming, feeding, and growth of Micropterus salmoides
Frontiers in Marine Science, 2023 Aquaculture systems, replete with equipment noise originating from aerators, pumps, feeders, and filtration systems, are known to exert substantial influence on fish behavior and growth.

Open ocean ambient noise data in the frequency band of 100 Hz–50 kHz from the Pacific Ocean [PDF]
JASA Express Letters, 2023 Bubbles from wind generated breaking surface waves are the dominant ambient noise source [Dean and Stokes, Nature 418, 839–844 (2002)]. With ambient noise data collected in the open ocean between 100 Hz and 50 kHz from 1999 to 2022, the ambient noise ...

The Alpha stable distribution in ocean ambient noise modelling [PDF]
MATEC Web of Conferences, 2019 In view of the non-Gaussian of ocean ambient noise, the stable distribution is applied to the statistical modelling. Firstly, the one-to-one correspondence between the four parameters of stable distribution and the sample mean, variance, skewness and ...

Review of Research Results Concerning the Modelling of Shipping Noise
Polish Maritime Research, 2021 The effect of underwater radiated noise (URN) pollution (produced by merchant ships) on marine ecology has become a topic of extreme concern for both the academic community and the general public. This paper summarises some research results and modelling
