A detailed study of low-frequency noise complaints [PDF]

, 2008
From 203 cases of low-frequency complaints a random selection of twenty-one cases were investigated. The main aim was to answer the question whether the annoyance is caused by an external physical sound or by a perceived but physically non-existing sound,

Effects on spatial skills after exposure to low frequency noise

, 2004
A study of spatial skills was conducted with 27 male and 27 female participants. The aim of the study was to examine the post-exposure effect of a complex low frequency noise (21 Hz) on a mental rotation task.

Low frequency noise enhances cortisol among noise sensitive subjects during work performance

, 2002
Salivary free cortisol concentration, rated stress and annoyance were determined in 32 subjects before, during and after carrying out a battery of performance tasks for 2 hours during exposure to ventilation noise, with dominant low frequencies (low ...

RTS noise impact in CMOS image sensors readout circuit [PDF]

, 2009
CMOS image sensors are nowadays widely used in imaging applications even for high end applications. This is really possible thanks to a reduction of noise obtained, among others, by Correlated Double Sampling (CDS) readout.

Electronic Noise Measurement of a Magnetoresistive Sensor: A Comparative Study

Sensors
The intrinsic noise of giant magnetoresistive (GMR) sensors is large at low frequencies, and their resolution is inevitably significantly limited. Investigation of GMR noise requires the use of measurement systems that have lower noise than the sample ...

Experimental Characterisation of the Low Frequency Noise Annoyance Arising from Industrial Plants

, 1992
Complaints about low frequency noise annoyance are frequently reported although the sound levels, measured according to usual procedures, do not seem to justify such reactions.
