ACOUSTIC MEASUREMENTS IN OPERA HOUSES: COMPARISON BETWEEN DIFFERENT TECHNIQUES AND EQUIPMENT

Journal of Sound and Vibration, 2000
Abstract In room acoustics, many objective parameters to quantify subjective impressions have been introduced. These quantities can be measured by using a wide variety of powerful tools and equipment. The results can be influenced by the measurement techniques and instruments used. Furthermore, the results also depend on the measurement positions and

An appraisal of techniques and equipment for cutting force measurement

Journal of Zhejiang University-SCIENCE A, 2006
Current research focussed on the assessment of metal machining process parameters and on the development of adaptive control, shows that machine performance, work-piece and tool material selections, tool life, quality of machined surfaces, the geometry of cutting tool edges, and cutting conditions are closely related to the cutting forces.

Ultrasonic Technique and Equipment for Residual Stresses Measurement

2011
Different methods exist to measure the residual stresses (RS). One of the advantages of ultrasonic techniques for RS measurement is that they are non-destructive. Using such techniques, one can measure the RS in the same points many times, studying, for instance, the changes of RS under the action of service loading or effectiveness of stress-relieving

Self-measurement of blood pressure: accuracy, patient preparation for readings, technique and equipment

Blood Pressure Monitoring, 2001
Self-measurement of blood pressure is commonly performed by those persons with hypertension and is advocated in many national hypertension guidelines. We examined accuracy of readings, patient knowledge, and preparation for readings, technique and equipment.The study was a prospective observational design.

Errors in body temperature assessment related to individual variation, measuring technique and equipment

International Journal of Nursing Practice, 2004
Errors in body temperature measurement might seriously influence the evaluation of an individual's health condition. We studied individual variation, measurement technique and the equipment used when assessing body temperature. In the first part of the study, three volunteers performed repeated measurements for five mornings.

Practical techniques for measuring partial discharges in operating equipment

[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
Several viable online partial-discharge (PD) tests have been developed for monitoring the condition of the solid dielectric insulation in high voltage equipment. The main requirement for on-line tests is the ability to reduce or eliminate noise. Such noise can create false indications that the insulation is failing, which in turn destroys the test's ...

Radiation standards and measurement techniques for personal-portable communications equipment

IEEE Transactions on Vehicular Communications, 1966
Radiation characteristics of personal-portable communications devices tend to vary more widely than perhaps any other operating parameter, and yet in many cases, this characteristic is the determining factor in the range and effectiveness of these devices.

Photographic Granularity and Graininess IX Techniques and Equipment for the Objective Measurement of Graininess*

Journal of the Optical Society of America, 1957
A photoelectric scanning instrument is described which gives granularity values in terms that can be converted into the graininess values that would be obtained by an observer viewing a magnified image of the sample under standard conditions. The procedure is to determine the critical scanning aperture that results in a signal corresponding to the ...
