In Illinois, for example, civil-liberties advocates are challenging a law that says you can be thrown in jail for 15 years for recording a conversation with a police officer.
The use of weighting networks gives a single number as a measure of vibration exposure and is expressed as the frequency-weighted vibration exposure in metres per second squared (m/s2), units of acceleration. Vibration meters equipped with accelerometers can be used for instantaneous vibration measurement.
What is a seismograph. A seismograph, or seismometer, is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions.They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs. seismograph, or seismometer, is an instrument used to detect and record seismic waves.
