In general, it has two basic areas of application in sound control--as a barrier used to block sound paths, and as a damping material for structures and surfaces to reduce transmission of vibration and radiation of airborne sound. Within each of these areas, there are many variations and specialized uses of lead and mixtures of lead and other materials. Perhaps the primary reasons for its continuing popularity is its extreme versatility and simplicity -- even for the uninitiated. It can be cut with a common scissors, molded and shaped to any contour, and is unaffected by solvents, coolants, cutting oils and other materials used in industry. It can readily be laminated to other materials such as wood and steel, and is often mixed with other materials such as epoxy and plastic to produce an effec tive tound absorbent with a broad range of properties. For example, lead powder mixed with various plastics and epoxies forms a compound that am be troweled onto rexmating machinery guards and shrouds to form a.'thsck sound absorbent that retains flexibility and resil iency. It out be sprayed, bonded or coated onto or into metal pans and machinery to reduce and contain sound at its source. Lead powder in vinyl with a fabric backing is commonly used as a curtain or shroud to enclose noisy operations and procoses. Used as an isolation pad under equipment and even structural components in buildings, kad is unsurpassed as a noise insulator. However, lead at a tound control is perhaps moat widely respected in budding construction applications such as those described briefly oo the following pages.

Chi cago. IL. combines living quarters and office plus retail stores, restau rants and perking garages m one structure Two primary noise prob lems were evident to the designers of the Puiidmg--the building would generate high noise level because of machinery and equipment need ed tor all the functions the building serves and wall construction be tween apartments had to be flexible to allow for building movement. This meant a problem of sound leakage from one apartment to the next. The solution to the machinery area noise problem was solved by nailing firring strips to the inside wall (standard concrete Mock) of each equipment room and titling the soace between strips with acousti cal wool Gypsum board sraa than nailed over the strips and 2W-lb. per square foot sheet lead (5/128* thick) waa placed over the wall board Edges of the sheet lead were forded into lock seams and sealed with duct tape A second course of gypsum board wee than installed to Mah the wad*. Two factors had so be taken Ms account in the design of the sound barriers between apartments- the movement of the building in the wind, and the narrow width of the muiliona where the inside walla joined the perimeter walla. Two pieces of H' gypsum board were used on either side of 3S' metal studs. The void between the gyp sum boards was filled with acous tical wool These wall* were car ried to within 25' of the perimeter walls where the will was narrowed to 1H" to match the width of the mullion. A channel 2' deep and ts` wide was attached to the mullion and floor and overhead spandrel. Gypsum. H* thick, was fitted insida the channal allowing a w* air space. Two sheets of 2 vt' lead ware screwed on ths tides of the chan nel and draped up over the span drel. Where |omts occurred in the sheet lead, closure was made by making Hat lock seams and sealing them with duct tape. The wall waa finished off on each side with W* thick gypsum board, and all lOints around the perimeter of the stub wall wart caulked to provide an air tight seal. * >5 JULY. 1822 Lee Srwat i*td waa used on ms went ot machinery rooms to reduce me nose generated by equipment xj eeoeoteoi* souno levee Signr The mutSon donums tM* suck eeebone ties connect me dry wane with me mut tons ere eound conditioned by etc use or 21S lb per sq. fl (5/125*suck anew lead on aacn side of the closure Tne closure nes the narrm* mullion to the eh'-Suck dfy was con struction T LIA03731 ease study BOIUMHG OPERATING MANAG***RNT-Ju ly, 1971 special issue on Sound ControlCase Histories ons Tufts New England Medical Center, Boston Baldvin-Wallace College, Berea, Ohio Tufts --________ Medical Center Boston, MA T1n Tufts Haw England Med ical Canter covers most of a 13 sort sits, snd consists of s "teaching" hospital complete with patients' rooms, examina tion rooms, nurses' stations, sup ply rooms, shopping arcades, motel end a theater.

Much of this new type of design is being employed on eastern Long Island where school building is undergoing a boom A current project at Bcllport. N Y., incorporates both old xnd~nw design viewpoints- The structure in question, a junior high school, is being enlarged. Both the original building and the addi tions were designed by the architectural firm of Frederick A. Allardt Jr. of Brookhaven. NY The older section of the school has masonry partitions while the new action makes Liberal use of fold ing part tv-s. The -:?* fleflpon school addition com prises two main areas an auditorium at one side of the existing building, a gym nasium and classroom complex at the op posite side Both additions conform m outward appearance to the older section of the school. In the interior, however, a total of 14 folding part Lions are em ployed. one in the gymnasium, one in the auditorium and 12 a classrooms. To preserve damroom quiet, the fold ing partiooas have a sound transmission dess of 40. As the folding paruuoos ex tend only as high as the hung ceilings, the ^ce between each partition-channel and the ceiling slab has to be sealed against the passage of sound traveling through the ceiling, over the top of Ac partition and into the next classroom. The acoustical contractor. Gilbert L. Phillips, Jf-, determined that the beat way to Modi this flanking path was by the uae of sheet lead pfanums The lead plenums have a high performance level yet low msullatioe cost. The huge gymaamum is designed so that it can be divided into two activity areas by the use of soundproof, wood, folding doors with com of aomiotiril wood The join* between foe folding panels art wcO gnfoeted and foe peach have sweeps at the bottom.

Cable Bmiectod Against All Hazards To provide the cable with maximum protection from man-made hazards, ranging from an atomic explosion to cutting by the blade of a plow, job specifications call for the cable to be buried to a depth of 4 feet through all types of rock and soiL Since such a procedure makes the cable almost inaccessible for maintenance, every precaution is taken to assure maximum reliability. For this reason^ "Coax 22" is covered with a lead sheath and a protective outeT polyethylene jacket. The lead sheath is extruded around the cable core to a thickness of 7/64th of an inch and weighs 4.7 pounds per foot Nominal outside diameter of "Coa* 22* is three inches. In places where the cable is intended for underwater service it is further protected by a steel wire armor to give it additional tensile strength. The lead sheath can be extruded in almost endless lengths but the cable reel's maximum capacity in this case is 1,750 feet ... limited by the straoder for the paired cable core. In actuality, the cable runs vary in length to eliminate the possibility of reflected signals. The cable reels are shipped from Western Electric's Baltimore Works to reel yards located along the cable route. Each reel is identified for a predetermined laying sequence. lead market Coaxial Cable SOOCE DIGEST NEW TOOK. A T.

Carbon monoxide is an in sidious menance that gives no fore warning and produces effects that are not always quickly detected.

The speed of sound is fixed at 1100 before being loosed in air. Thus, damping mounts help reduce noise to the extent that potential sound feet per second, but just as in water, waves in air may vary in height (amplitude) and in aest-ttxrest waves travel in their direction.

And zinc importers com plained that the imposition of the US import surcharge on zinc and the adjust ment of international currency exchange rates had cut tmo their profits and made the US oot a particularly attractive market. Adding to the confusion was the fact chat it was impossible to determine how much oi the immediate zinc shortage should be attributed to (he withdrawal of some US producers from the market end how much to the permanent shut down oer the pan two years of erneHere accounting for about 40% of US tine metal output. Most projections for die US economy call for a continued business upturn through the rest of 1972 And it is poasiWe that even the return of all producers to the market once the Government hai the price utuation straightened out --would not completely satisfy the de mand for bac irom US buyers, accord ing to certain wMl-ufformed industry Asked if heavy demand far zinc mould be taken at face value, oar sales executive replied.
