General and Comfort Ventilation 2 The system must be able to throttle smoothly over the total range of turndown (which can be as much as 25 1) 3 Burner must be able to produce complete combustion of the fuel throughout the turn down range 4 Flame retention and stability must be maintained in high velocity flow of air So-called "line burners" are almost ex clusively used because they give uniform temperature distribution across the air stream Line burners are sectional burners available in a variety of shapes which are flanged so they can be bolted together into assemblies to fit the size and shape of the unit Air-gas proportional' and premixing equipment is required, as is a positive flame retention fea ture A single flame failure or combustion safeguard device is usually satisfactory, as is a single gas pilot for ignition The widerange type line burner was developed espe cially to meet the needs of air heating as it utilizes oxygen from the stream of air being heated to supplement that provided m the primary air-gas mixture in order to extend the range of turndown to the 25 1 figure re quired Be sure that heater manufacturer's recommendations arc followed in installa tion, especially with regard to velocity of air flow across burner Steam Where excess steam capacity is available, use of steam coils or finned heaters should be considered carefully as steam heaters are relatively simple, inexpensive, easily maintained, and require no combus tion safety equipment Precautions which must be taken when using steam include 1 Avoid long heating coils These may give uneven temperature distribution from side to side in the duct as the steam supply is throttled over the wide range of turndown required (20 1 to 25 1) 2 Protect against freezeup Outside air at subfireezing temperatures can be drawn over the heating coils 3 Consider use of oil- or gas-fired tempenng air heaters ahead of steam coils to reduce load during extreme low-temperature weather (which can already put a maxi mum heating load on boilers) It is important that a qualified ventilation engineer be consulted References American Conference of Governmental Industrial Hygienists, Committee on Industrial Ventila tion, PO Box 453, Lansing, Mich 48902 Industrial Ventilation--A Manual of Recom mended Practice, 9th ed 1966 American Cas Association, 420 Lexington Ave , New York, NY A Complete Guide to Direct Gas-Fired Heating of Process Makeup Air 1961 American Society of Heating, Refrigerating and Air-Conditioning Engineers, 345 East 47th St, New York, N Y Guide and Data Book, `Fundamentals and Equipment' (Issued annually ) Bedford, T Environmental Warmth and Its Measurement Medical Research Council War Memorandum No 17 1946 Belding.

Industrial Noise Oims Media An inflammation and in fection of the middle ear Otologist A physician who has spe cialized in surgery and diseases of the ear Otosclerosis Hardening of the ear caused by a growth of bony tissue about the foot plate of the stapes and the oval window of the inner ear It results m a gradual loss of hearing Surgery can often correct this Paracusis Willisii The sensation of a deafened person indicating that he can hear better in a noisy area Pitch That attribute of auditory sensa tion in terms of which sounds may be ordered on a scale extending from low to high Pitch depends primarily upon the frequency of the sound stimulus, but it also depends upon the sound pressure and wave form of the stim ulus Power level The level, m decibels, is 10 times the logarithm to the base 10, of the ratio of a given power to a reference power The reference power must be indicated Presbycusis The hearing loss due to age It is believed by some to be the degen eration of the nerve cells due to the ordinary wear and tear of the ageing process Psychogenic deafness That originat ing in or produced by the mental reaction of an individual to his physical or social en vironment It is sometimes called functional deafness or feigned deafness Recruitment The condition m which an individual perceives an abnormallv rapid increase m loudness as the sound pressure goes up It is usually characteristic of severe sensorineural deafness Response The motion of a device or system (or other output) resulting from an excitation (stimulus) under specified con ditions Reverberation The persistence of sound in an enclosed space, as a result of mul tiple reflections after the sound source has stopped Sensorineural deafness Nerve deaf ness or the lack of sensitivity of the auditory mechanism in the cochlea or paralysis of the acoustic nerve This was formerly called inner ear impairment or perceptive deafness Semicircular canals The special organs of balance that are closely associated with the hearing mechanism and the eighth cranial nerve Simple tone (pure tone)-(a) A simple tone is a sound wave, the instantaneous sound pressure of which is a simple sinusoidal func tion of the time, (b) a simple tone is a sound sensation characterized by its singleness of pitch Single frequency screening test A fast method of rechecking hearing acuity using the 4000 Hz frequency The meas ured value of the threshold at 4000 Hz up to 50 dB can be considered an upper limit for any threshold shift that might have occurred at other lower frequencies Sone A unit of loudness By definition, a simple tone of frequency 1000 Hz, 40 dB above a listener's threshold, produces a loud ness of 1 sone The loudness of any sound that is judged by the listener to be n times that of the 1-sone tone is n sones Sound An oscillation m pressure, stress, particle displacement, particle velocity, etc , which is propagated in an elastic material, in a medium with internal forces (e g , elastic, viscous), or the super-position of such prop agated oscillations Sound is also the sen sation produced through the organs of hear ing--usually bv vibrations transmitted in a material medium, commonly air Sound absorption The change of sound energy into some other form, usually heat, in passing through a medium or on striking a surface In addition, sound absorption is the property possessed by materials and ob jects, including air, of absorbing sound energy Sound analyzer A device for measur ing the band-pressure level or pressurespectrum level of a sound as a function of frequency SOUND level \ weighted sound pres sure level, obtained by the use of metering characteristics and the weighting A, B, or C specified in ASI SI 4-1961 The weight ing employed must always be stated The reference pressure is 0 0002 microbar Sound level meter and octave band ANALYZER Instruments for measuring 1520
