The following topics will be considered: Noise characterisation of voltage amplifiers in series. Noise measuring set-up with dc excitation and single ended ac-amplifier or differential amplifier in a bridge configuration. Bias and sample criteria to observe 1/f noise in homogeneous samples submitted to homogeneous fields. Criteria for highest S V value

Noise and the measurement of noise quantities
1996Sensitivity and noise factor are the conventional parameters which describe the, capability of a system to process weak signals. The noise factor is particularly important, since it characterises not only the system as a whole but also its modules (such as HF preamplifiers, mixers, or IF amplifiers).

Measurement Amps, Noise Generators and FFT Noise Measurements
2011In 1989 M. Wilfried Adam published a great article on the design of low-noise audio amps. The complete circuitry of a noise measurement system (MS) also became part of that article. M. Adam described all necessary measurement filters too. Instead of buying a very expensive all-in-one measurement instrument a few months later I decided to develop my own

The noise dosimeter for measuring personal noise exposure
Acta Oto-Laryngologica, 1970A pilot study of personal noise exposure measurements with the use of noise dosimeters is presented. The value of objective individual recordings regarding the intensity and the exposure time is emphasized. Unexpected daily variations were detected also among employees assumed to work in fixed noise—level environments.

Equal-noise spectroscopic measurement
Applied Optics, 1984An experimental spectroscopic method that allows arbitrary uncertainties of measurement without a priori knowledge of a source emission rate is presented. The method is fully developed using as an example a Fabry-Perot spectrometer examining a line source for Doppler width and shift information.

Environmental noise is widely noted as a form of "pollution." Measurement of noise intensity as a function of frequency is essential to its understanding and control. This is a tutorial paper summarizing standard current techniques and precautions to be followed in measuring environmental noise.
