Crosstalk measurement is made on audio systems to determine the amount of signal leaking across from one channel to another. Interchannel crosstalk applies between the two channels of a stereo system, and is usually not very important on modern systems, though it was hard to keep below the desired figure of 30dB or so on vinyl record ings and FM radio . Crosstalk between channels in mixing consoles, and between studio feeds is much more of a problem, as these are likely to be carrying very different programmes or material. The IBA drew up a weighting curve for use in crosstalk measurement that gives due emphasis to the subjective audibility of different frequencies, as shown here. This is still in use, despite the demise of the IBA, and in the absence of any international standards is worth adopting.

Work measurement is the application of techniques designed to establish the time for a average worker to carry out a specified manufacturing task at a defined level of performance ref Groover, M. P. 2007 . Work Systems The Methods, Measurement & Management of Work , Prentice Hall, ISBN 9780131406506 ref . It is concerned with the length of time it takes to complete a work task assigned to a specific job. Usage Work measurement helps to uncover non standardization that exist in the workplace and non value adding activities and waste. A work has to be measured for the following reasons To discover and eliminate lost or ineffective time. To establish standard times for performance measurement. To measure performance against realistic expectations. To set operating goals and objectives. Techniques of Work Measurement time study Predetermined motion time system Predetermined motion time systems Standard Data Work sampling Uses of Work Measurement To compare the efficiency of alternative methods. Other conditions being equal, the method which takes the least time will be the best method. To balance the work of members of teams, in association with the multiple activity charts, so that, as far as possible, each member has tasks taking an equal time.

Noise measurement is carried out in various fields. In acoustics , it can be for the purpose of measuring environmental noise , or part of a test procedure using white noise , or some other specialised form of test signal . In electronics it relates to the sensitivity of communications systems, the purity of signals, or the quality of audio systems . The concept is to define the noise level below which signals cannot reliably be detected. It can be thought of as uncertainty of the information being carried over a communications channel . In audio systems and broadcasting specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the differing spectral distribution and temporal properties of the noise that they generate. In particular, the ITU R 468 noise weighting was devised specifically for this purpose, and is widely used for professional audio and broadcast measurements. Standards There are a number of standards for noise measurement, each with a different goal or focus, including Standard ITU R BS 468 widely used in Broadcasting and professional Audio. Standard IEC A weighting is widely used in Environmental Noise measurement. Standard CCIR recommendation 468 4 is now maintained as ITU R BS 468 Standard CCITT 0.41 refers to Psophometric weighting used on telephone circuits. Standard CCITT P53 is now continued as CCITT0.41 Standard BS 6402 1983 specifies Personal sound exposure meters. Standard BS 3539 1968 specifies Sound level meter s for motor vehicle noise.

POV check date November 2010 Weak measurements are a type of quantum measurement , where the measured system is very weakly coupled to the measuring device. After the measurement the measuring device pointer is shifted by what is called the weak value . So that a pointer initially pointing at zero before the measurement would point at the weak value after the measurement. The system is not disturbed by the measurement. Although this may seem to contradict some basic aspects of quantum theory, the formalism lies within the boundaries of the theory and does not contradict any fundamental concept. The idea of weak measurements and weak values, first developed by Yakir Aharonov , David Albert and Lev Vaidman ref Y. Aharonov, D.Z. Albert, L. Vaidman, How the result of a measurement of a component of the spin of a spin 1 2 particle can turn out to be 100, Physical Review Letters, 1988. http prola.aps.org abstract PRL v60 i14 p1351 1 ref is especially useful for gaining information about pre and post selected systems described by the Quantum state two state vector formalism . ref Y.

merge Quantum mind body problem date November 2010 The measurement problem in quantum mechanics is the unresolved problem of how or if wavefunction collapse occurs. The inability to observe this process directly has given rise to different interpretations of quantum mechanics , and poses a key set of questions that each interpretation must answer. The wavefunction in quantum mechanics evolves according to the Schr dinger equation into a linear Quantum superposition superposition of different states, but actual measurements always find the physical system in a definite state. Any future evolution is based on the state the system was discovered to be in when the measurement was made, meaning that the measurement did something to the process under examination.
