2. Noise sources and their measurement
www.who.intTo approximate the integration time of our hearing system, sound pressure meters have a standard Fast response time, which corresponds to a time constant of 0.125 s. Thus, all measurements of sound pressure levels and their variation over time should be made using the Fast response time, to provide sound pressure measurements more ...
Blood Pressure Monitor - Fundamentals and Design - NXP
www.nxp.comThe functionality of the oscillometric method is based on the measurement of the pressure variations in the arm cuff. Pressure in the cuff is measured by using the Freescale Pressure Sensor MP3V5050 which integrates on-chip, bipolar OpAmp circuitry and thin film resistor networks to provide a high output signal and temperature compensation.

omronhealthcare.com7. Keep a record of your blood pressure and pulse readings for your physician. A single measurement may not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time. Try to measure your blood pressure at about the same time each day for consistency.
