With this procedure, duration as a parameter was used to determine the temporal summation characteristics of ten normal ears. An apparatus was constructed that permitted subjects to track threshold by modulating the burst width of a brief tonal stimulus. The apparatus permitted experimenter control of the rate of burst width modulation and interburst interval. The burst width could be continuously varied by the subject from 10 to 800 msec. Asymptotic regression indicated that the data were best fit to a simple power function of the form Y = AX(B). A logarithmic transformation was applied to the obtained durations, and slopes of integration were determined for each frequency. These values ranged between 6.3 and 10.2 dB/log unit time. Differences among frequencies were found to be significant. Critical durations were obtained for each subject, and these values were consistent with previous data indicating negligible temporal summation about 150 to 200 msec.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"4 1","pages":"19-23"},"PeriodicalIF":0.0,"publicationDate":"1978-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11922099","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}

Recent research into the subjective effects of earmold venting indicates that, for the naive hearing-aid user, the solid mold produces a \"closed\" and \"blocked\" sensation that is relieved to a degree, depending on the vent diameter. To improve earmold comfort, all earmolds should be vented. However, there are certain types of hearing loss where conventional venting techniques would be undesirable, in particular, cases of severe to profound hearing loss where venting would not only adversely affect the desired frequency response characteristics of the hearing aid but would also lead to serious acoustic feedback problems. For this reason a simple system has been developed with sintered filters in the vent line, thus allowing all earmolds to be vented to relieve the occluded ear sensation although retaining the acoustic characteristics of the closed earmold.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"4 1","pages":"30-5"},"PeriodicalIF":0.0,"publicationDate":"1978-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11922102","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}
