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 ...

On the Statistics of Ambient Noise [PDF]
The Journal of the Acoustical Society of America, 1967 The statistics of ambient noise have been investigated previously for single receivers [A. H. Green, Bell Lab. Tech. Rept. No. 10, (1962)], but no studies were made for ambient noise with arrays. Data are presented for ambient noise measured with 30- to 60-element arrays. Amplitude samples of ambient noise were taken at 30-msec intervals. The period is

Shear-Wave Tomography Using Ocean Ambient Noise with Interference
Remote Sensing, 2020 Ambient noise carries abundant subsurface structure information and attracts ever-increasing attention in the past decades. However, there are lots of interference factors in the ambient noise in the real world, making the noise difficult to be utilized ...

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

Survey of ambient noise in aquariums. [PDF]
The Journal of the Acoustical Society of America, 2010 Owning and maintaining an aquarium is a common hobby, but the ambient noise in aquariums resulting from pumps, filters, bubblers, and other equipment is not well studied. Elevated ambient noise levels have been shown to adversely affect wild fish and marine invertebrates, and anecdotal evidence suggests that this may be a problem in aquariums as well ...
