A spectrogram of Bloop. Bloop is the name given to an ultra-low-frequency and extremely powerful underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. The sound is consistent with the noises generated by icequakes in large icebergs, or large icebergs scraping the ocean floor. [3]
This mechanism could explain the Bloop's wide detection range and distinct acoustic signature. [7] As oceanographer Yunbo Xie explains, the alteration of waveforms from a detected sound "can also be caused by so-called angular frequency dependent radiation patterns associated with antisymmetric mode motion of the ice cover."

The total range of the species is roughly 380 000 km 2. [10] In the 1980s, ... The mating call of the Ludwig's bustard is a deep ‘bloop’ noise. [12]
In broadcast engineering, a frequency extender is an electronic device that expands the usable frequency range of POTS telephone lines. [1] It also allows high-fidelity analog audio to be sent over regular telephone lines, without the loss of lower audio frequencies . It is an extended concept of a telephone hybrid.
XDR (expanded dynamic range), also known as SDR (super dynamic range) is a quality-control and duplication process for the mass-production of pre-recorded audio cassettes. It is a process designed to provide higher quality audio on pre-recorded cassettes by checking the sound quality at all stages of the tape duplication process.
To learn more about noise from the Cranston range, see Fang's reportand visit Brown's School of Public Health on Nov. 14 at 5:30 p.m. for a panel discussion in Room 241. The event is free to the ...
Psychoacoustic tuning curves can be measured using the notched-noise method. This form of measurement can take a considerable amount of time and can take around 30 minutes to find each masked threshold. [10] In the notched-noise method the subject is presented with a notched noise as the masker and a sinusoid (pure tone) as the signal.
Prices are somewhat high across a range of discretionary merchandise from jeans to shoes to phones, making the typical mall trip relatively expensive. Retailers that sell non-essential merchandise ...
