An attempt is made to screen the hearing of all Dutch babies between the ages of 8 and 12 months. At the age of 4 or over, general audiological care is given by the school medical service; referral is first to a family doctor, who may refer to an otolaryngologist. Curative medical care (examination and therapy) is the province of the family doctor and the otolaryngologist. Otolaryngologists and pediatricians can refer patients to one of 19 Audiological Centers distributed around the country, where a number of workers in different disciplines cooperate for habilitation and rehabilitation. These may include an otolaryngologist in charge, a psychologist, a speech and hearing therapist, an audiologist (usually a physicist or university-trained engineer), social worker, technician, ortho-pedagogue, audiology assistant, and teacher. There are at the moment 25 schools for the hard of hearing and 5 institutes for the deaf. These are often found in conjunction with Audiological Centers, the latter providing paramedical assistance to the pupils by agreement. Finally, the Dutch Organization for Preventive Medicine works to prevent hearing loss in noisy industries.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"3 1","pages":"34-6"},"PeriodicalIF":0.0,"publicationDate":"1977-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12077703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the coupler-acoustic technique the effect of venting was determined by measuring the output of the experimental earmolds seated on a modified 2-cc coupler with a specified signal impressed upon the earphone. The real ear threshold technique called for the determination of threshold by five listeners for the same earphone-earmold system. The data indicated that the difference between the coupler and threshold measures were of the same order of magnitude as the difference seen by other investigators reporting coupler and real ear-probe tube microphone measures. It was concluded that the threshold technique provides the same general description of the effects of venting an earmold as does the probe tube technique and should thus provide a useful method for determination of the filter effects produced by the venting of an earmold.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"3 1","pages":"6-9"},"PeriodicalIF":0.0,"publicationDate":"1977-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12076373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
