The periodicity pitch difference limens (DLs) based on changes in repetition rate were compared with frequency DLs obtained from low (150 Hz) and high frequency (2200 Hz) sinusoids. Periodicity pitch signals were generated by gating a 2200-Hz sinusoid over a range from 141 to 159 pulses per sec and passing the signals through a narrow band-pass filter to ensure no low frequency energy was present. The DLs (75% correct discriminations) were computed from the three types of discrimination performance curves. Standard errors of the means were small and retarded subjects showed good test-retest reliability. The results indicated that the simple and complex pitch discrimination abilities for both normal and retarded subjects were similar.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"2 4","pages":"142-50"},"PeriodicalIF":0.0,"publicationDate":"1977-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12029895","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}

Attemps to relieve tinnitus. 试图缓解耳鸣。

{"title":"Attemps to relieve tinnitus.","authors":"J Vernon","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The major effect here has been to present two forms of treatment which have provided relief of tinnitus for some patients. Use of a properly fitted hearing aid relieves tinnitus when that tinnitus is embedded within the frequency region of the hearing loss. When the use of a hearing aid is counterindicated, then use of the tinnitus masker can bring relief for certain kinds of tinnitus. At present the only tinnitus masker available presents a band of noise of moderate frequencies, and it is capable of relieving tinnitus in that frequency region or near it. When masking of tinnitus is effective it produces a suppresion of the tinnitus which extends beyond the duration of the masker. This is termed residual inhibition, a matter about which we need to know a great deal more. For tinnitus which is intractable to medical treatment it has become a practice to instruct the patient that he must learn to live with his affliction. It is hoped that this presentation will cast doubt upon that view, for it can be seen that there are many tinnitus sufferers for whom much can be done.</p>","PeriodicalId":76026,"journal":{"name":"Journal of the American Audiology Society","volume":"2 4","pages":"124-31"},"PeriodicalIF":0.0,"publicationDate":"1977-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12032024","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}

Also, the reference criteria for expressing distortion was observed to contribute to the inconsistency of rank order impression.
