Today's technology being then unknown made development of the singing voice entirely dependent upon the ear, the good taste in style, and the musicality of the teacher. \u0000The vocal needs today require bigger voices due to present day size of concert halls and opera houses. They are larger in every way over performing areas of the past. Filling these spaces, a singer must have an energized instrument which \u0000necessitates finding new avenues that point the way to increased vocal energy without harming the voice, i.e.balanced resonance. Computer analysis programs which are relatively inexpensive and readily portable fitwell into voice studios. Energies such as harmonics (formants), vowel consonant relationship and vibrato can easily be checked on a computer screen.","PeriodicalId":39902,"journal":{"name":"Canadian Acoustics - Acoustique Canadienne","volume":"24 1","pages":"34-34"},"PeriodicalIF":0.0,"publicationDate":"1996-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64322614","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}

The comparinon is based on the results of tests on 60 diesel trucks covering a range of ages, sound levels and configurations. The CSA procedure is found to be at least as good a predictor of pass-by sound levels as RP J1096 and can be used on smaller and noisier sites. The results of some exploratory measurements of the effects of wind and temperature gradients on the repeatability of the two procedures are also presented and discussed.","PeriodicalId":39902,"journal":{"name":"Canadian Acoustics - Acoustique Canadienne","volume":"8 1","pages":"31-39"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4271/800277","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70837593","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}
