A newer but less knowntechnique employing a "pull" maneuver,involving lifting of the body at the hips,is the Emerson method, the doctorssuggested:"Those who are now indoctrinatedwith the Schafer prone pressure methodcan double the ventilating efBciency ofthe method by lifting the hips fourInches 12 times each minute, alternatingwith a 'push' on the lower part of thechest. Lifting the hips is fatiguing and,after the crucial first several minutes,may be employed after every second orthird 'push' on the lower part of thechest."• • • •EAR INJURIES ARE THREATOF NOISE IN INDUSTRYThe control of ear injuries due to excessivesound—the most frequent threatto the ears of workers today—^is a majorresponsibility of Industrial medicine,according to Raymond Carhart, Ph.D.,of Evanston, HI. Dr. Carhart is associatedwith Northwestern UniversitySchool of Speech and Department ofOtolaryngology.Auditory impairment due to excessivesound, known as coustic trauma, damagesthe ears without doing other physiologicalharm, he pointed out in theArchives of Industrial Hygiene and OccupationalMedicine, published by theAmerican Medical Association.Dr. Carhart said that acoustic traumacan be caused by a number of things:continuous noise, steady soimd at highIntensities, soimd of percussive and explosivevarieties, and pulsating noises,especially when unexpected and irregular.He cited the pneiunatic hammeras a good example of "a dangerouslystrong percussion soimd."A full program for protecting the"ears of industry," he said, can be effectiveonly if endorsed by both managementand labor. This Is his proposedthree-point program:1. Noises should be controlled withsound absorbing materials, by mutingdevices, or, if possible, by replacementwith new, noiseless machines. If noisecannot be controlled by these methods,workers should be required to wear eardefenders.2. A program of ear and hearingexamination—for the protection of boththe worker and his employer—shouldbe carefully planned.3. Analysis of each individual caseshould be the basis for appropriate joballocation. Workers with hearing lossesor those susceptible to acoustic traumashould not be placed in situations wheretheir impairment might constitute ahazard to themselves or others.* • * *TRANSCRIPTION OF TEEN-AGEHEALTH PROBLEMS RELEASEDThe Bureau of Health Education ofthe American Medical Association announcedthe release of 13 electricaltranscriptions of Interviews with highschool pupils on teen-age health problems.The subjects, together with the citiesin which the recordings were made,are as follows:Detroit, "Youth at the Wheel;" Pittsburgh,"How to Be Popular;" SanFrancisco, "Looking Your Best;" Colxunbus,C, "Extra-Curricular Activities;"Phoenix, "Dope, Drugs andSmoke;" Lake Mills, Wis., "Food andYour Health;" Portland, Oregon, andChicago, "Sports and Recreation;"Madison, Wis., "Date With the Doctor;"Cleveland, "Out-of-School Jobs;" Indianapolis,"Big and Beautiful;" St.Paul, "Choose Your Partner;" Austin,Tex., "First Offender;" Brooklyn, "Fearsand Fancies."The series, known as "Hi-Forum,"comprises interviews made by tape recordingswithout scripts.
