Dolorimeter From Wikipedia, the free encyclopedia. A dolorimeter is an instrument used to measure pain threshold and pain tolerance. Dolorimetry has been defined as the measurement of pain sensitivity or pain intensity.. Several types of dolorimeter have been developed. Dolorimeters apply steady pressure, heat, or electrical stimulation to some area, or move a joint or other body part and determine what level of heat or pressure or electric current or amount of movement produces a sensation of pain.

Noise - Basic Information For instance, using the example of two machines each emitting a noise level of 90 dB: 1  Step 1: The numerical difference between the two levels is 0 dB (90-90= 0), using the first row. 2  Step 2: The number corresponding to this difference of 0, taken from the right hand column, is 3. 3  Step 3: Add 3 to the highest level, in this case 90.

Noise Sound is measured based on the amplitude and frequency of a sound wave. Noise is most commonly discussed in terms of decibels (dB), the measure of loudness, or intensity of a sound; this measurement describes the amplitude of a sound wave.

Signal-to-noise ratio Signal-to-noise ratio (abbreviated SNR) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.It is defined as the ratio of signal power to the noise power, often expressed in decibels.he signal-to-noise ratio, the bandwidth, and the channel capacity of a communication channel are connected by the Shannon–Hartley theorem. Signal-to-noise ratio is sometimes used informally to refer to the ratio of useful information to false or irrelevant data in a conversation or exchange.

Noise temperature Main article: Noise figure. One use of noise temperature is in the definition of a system's noise factor or noise figure. The noise factor specifies the increase in noise power (referred to the input of an amplifier) due to a component or system when its input noise temperature is T 0 {\displaystyle T_{0}} .

What are A, C & Z Frequency Weightings? These are electronic filters within the the instrument that are used to adjust the way in which the instrument measures the noise. The most commonly used Frequency Weightings that you will see on a modern sound level meter or noise dosimeter are ‘A’, ‘C’ and ‘Z’ and below is a brief explanation of each of these.

What is Noise Reduction Rating What is Noise Reduction Rating. A noise reduction rating indicates the level of sound that earplugs block out when used without simultaneous noise-blocking objects. This rating applies only to earplugs and earmuffs and provides users of these devices an important analytical tool when comparison shopping.

Definitions &Translations Dosimeter. Dosimeters measure an individual's or an object's exposure to something in the environment — particularly to a hazard inflicting cumulative impact over long periods of time, or over a lifetime. This article concentrates on the radiation dosimeter, which measures exposure to ionizing radiation.

What is ultrasonic flow meter? The Doppler Effect Flow meter uses reflected ultrasonic sound waves to measure the velocity of particles in the fluid. By measuring the frequency shift between the ultrasonic frequency source, the fluid carrier, and the receiver, the relative fluid velocity is measured.

Tuned Mass Dampers Tuned Mass Dampers >> Home » Tuned Mass Dampers A Tuned Mass Damper (TMD) is a mechanical device designed to add damping to a structure for a certain range of exciting frequencies. The extra damping will reduce the movement of the structure to an acceptable level. A tuned mass damper contains a mass that is able to oscillate in the same direction as the structure. The oscillation frequency of the mass can be tuned using springs, suspension bars, or ball transfers. When the structure starts to oscillate, the mass of the TMD will initially remain stationary due to inertia.

Dosimeter Gate oxide of MOSFET which is conventionally silicon dioxide is an active sensing material in MOSFET dosimeters. Radiation creates defects (acts like electron-hole pairs) in oxide, which in turn affects the threshold voltage of the MOSFET. This change in threshold voltage is proportional to radiation dose.
