An ultralow noise preamplifier for low frequency noise measurements
Review of Scientific Instruments, 2009Low frequency noise measurements are among the most sensitive tools for the investigation of the quality and of the reliability of semiconductor devices. The sensitivity that can be obtained depends on the background noise of the low noise preamplifier coupled to the device under test (DUT) that, at very low frequencies, is dominated by flicker noise ...

Low-frequency noise thresholds
Journal of Sound and Vibration, 1969Abstract The absolute threshold of hearing for octave bands of noise with centre frequencies from 125 to 4 Hz has been determined. The results show that the noise threshold behaves in a similar fashion to the tone threshold, but below 32 Hz noise thresholds are more sensitive by a small but significant amount. A hypothesis is advanced that from about

The Journal of the Acoustical Society of America, 1986
Since the classic paper of Wenz [J. Acoust. Soc. Am. 34, 1936 (1962)], ambient noise has been an extensively studied phenomena. Morris [SIO Ref. 75-34, MPL/Scripps (1975)] emphasized the importance of ships as their signals are enhanced when they cross over seamounts or proceed over the continential slopes. Wagstaff [J. Acoust. Soc. Am. 69, 1009 (1981)]

Analyzing motorcycle low-frequency noise
Journal of Theoretical and Computational Acoustics, 2022This paper presents analyses of the 3D acoustic fields generated by motorcycles at very low frequencies ([Formula: see text] Hz) at the idle speed and during sudden acceleration. Diagnosis and analyses of sound sources at low frequencies have always been a significant challenge because the directivity of low-frequency sound is very poor.

Ultra-low-noise regenerative frequency divider
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012We designed ultra-low-noise regenerative divide-by- 2 circuits that operate at input frequencies of 10, 20, and 40 MHz. We achieved output-referred single-sideband residual phase noise equal to -164 dBc/Hz at 10 Hz offset and estimated residual Allan deviation, σ(y)(τ) less than 3 × 10(-15)τ(-1) for a single divider, which is, to our knowledge, the ...

Europhysics Letters (EPL), 1986
At the nucleation stage of phase transformation, the number of critical nuclei is slowly fluctuating, which should lead to a characteristic, electrically detectable, low-f noise. Observation of this noise, which has a well-defined cut-off would provide an internal kinetic test of classical nucleation models.

Low-frequency noise in low 1/f noise dc SQUID’s
Applied Physics Letters, 1986We demonstrate that the low-frequency noise in our edge junction dc superconducting quantum interference devices, with a basic 1/f flux noise of 2×10−12 Φ20/Hz at 1 Hz, can all be accounted for in terms of junction critical current fluctuations. A novel modulation readout scheme is able to cancel the effect of junction critical current fluctuations and
