data logging

Science; Acoustics

On-going measurements, stored at regular intervals for downloading to a PC.

Or decibel watt is a unit for the measurement of the strength of a signal expressed in decibels relative to one watt. It is used because of its capability to express both very large and very small ...

nominal frequency

Science; Acoustics

Or preferred frequency - a specified octave or fractional-octave filter as defined by the ISO and ANSI standards.

sine wave

Science; Acoustics

Or pure tone is characterized by it's frequency (number of cycles per second) or it's wavelength (distance it travels within a period) and the amplitude .

wave number

Science; Acoustics

Or wavenumber is the spatial frequency of a wave, either in cycles per distance or radians per unit distance. It can be envisaged as the number of waves that exist over a specified distance ...

order tracking

Science; Acoustics

Order tracking is a special case of FFT analysis applied to variable-speed rotating machines where the sampling frequency of the analyzer is varied to be an exact multiple of the running speed of the ...
