Identifiability Can I be evaluated When subjects were told the sound equipment could measure their individual clapping as well as the team effort, social loafing disappeared (Williams et al., 1981). Thus, when subjects believed their personal effort could be... 

All soundings shall be carried out by means of a recording trace dual frequency echo-sounder with sufficient sensitivity to permit measurement of the bed levels to an accuracy of +/-100 mm. The echo sounding equipment shall be regularly calibrated by means of a sounding plate. 

A mechanics-free airborne sound location system is used in order to record the probe movement and the rotation direction of the probe relative to the weld. Two airborne sound transmitters are arranged on the probe holder and two receivers are fixed on a 50 cm long rail equipped with two magnetic pads The exact probe position and rotation direction is continuously determined by system. 

It should be specially pointed out, that modem equipment for remote acoustics sounding gives the possibility to solve the most part of issues related to the water basin and river bottoms monitoring. 

Technical requirements Sound engineering practice, essential requirements tarticle 3t The directive includes a particular technical requirement with respect to equipment which presents only a minor pressure hazard. For such equipment the essential requirements and the certification procedures are not applicable. Instead the so-called sound engineering practice of one of the Member States must be applied. That practice must ensure that design and manufacture takes into account all relevant factors influencing safety during the intended lifetime. The equipment must be accompanied with adequate instruetions for use and must bear the identification of the manufacturer. The CE-marking shall not be applied for such equipment. 

The metal is very effective as a sound absorber, is used as a radiation shield around X-ray equipment and nuclear reactors, and is used to absorb vibration. White lead, the basic carbonate, sublimed white lead, chrome yellow, and other lead compounds are used extensively in paints, although in recent years the use of lead in paints has been drastically curtailed to eliminate or reduce health hazards. 

In most ultrasonic tests, the significant echo signal often is the one having the maximum ampHtude. This ampHtude is affected by the selection of the beam angle, and the position and direction from which it interrogates the flaw. The depth of flaws is often deterrnined to considerable precision by the transit time of the pulses within the test material. The relative reflecting power of discontinuities is deterrnined by comparison of the test signal with echoes from artificial discontinuities such as flat-bottomed holes, side-drilled holes, and notches in reference test blocks. This technique provides some standardized tests for sound beam attenuation and ultrasonic equipment beam spread.

Other sohd-state apphcations of sihcon carbide include its use as an electroluminescent diode for use in sound recording equipment and photomultipliers and controllers. It has been studied as a reflective surface for lasers. By combining its excellent thermal conductivity and high electrical resistance, sihcon carbide has also found apphcation as an insulating material for integrated circuit substrates. 

First, any analysis must be coupled with a technically correct interpretation of the equipment performance soundly rooted in the fundamentals of mass, heat, and momentum transfer rate processes and thermodynamics. Pseudotechnical explanations must not be substituted for sound fundamentals. Even when the development of a relational model is the goal of the analysis, the fundamentals must be at the forefront. 

When the unit was initially plaeed in serviee, sound level measurement data were eolleeted. Within 3 ft of the expander ease, sound levels were measured at 92-99 dBA. At the property line 25 ft away from the ease, the levels were 68-85 dBA. At the time of installation, there were no stmetures near enough to the faeility to be impaeted by any noise. However, as the surrounding area eontinues to develop, it may be neeessary to install sound attenuation equipment. 

The installed eost is primarily determined by the size of the unit. However, other faetors may have a signifieant impaet on this eost. The eonneetion to the gas system eould be expensive if speeial hot tap fittings are required. If sound attenuation is neeessary for the ehosen loeation, this ean also have an impaet on the overall eost. The eonneetion to the eleetrieal system ean add signifieant eost if distanees are far or high-voltage switehgear is neeessary. Equipment manufaeturers are able to provide eost estimates for major equipment. The installation eosts are site speeifie and require individual studies and estimates. 

The pursuit of product quality over the last few decades has been intense in many companies around the world, but in many sectors of industry, reliability is considered to be the most important quality attribute of the product (Kehoe, 1996). As consumers become more aware than ever of quality, their expectations for reliability are also increasing. Even equipment without obvious safety concerns can have important reliability implications. Most products can, therefore, benefit from the use of sound reliability techniques (Burns, 1994). Reliability prediction, in turn, has the benefit that it gives a quantifiable estimate of the likely reliability that can be assessed to see if this is appropriate for the market (Stephenson and Wallace, 1996).
